SUMMARY 概 要 :<br />

In resp<strong>on</strong>se <strong>to</strong> a request from Jiangxi Province Forestry Department, the Secretariat of the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong><br />

formed a team of experts <strong>to</strong> investigate the ecological envir<strong>on</strong>ment of <strong>Poyang</strong> <strong>Lake</strong> and the current situati<strong>on</strong><br />

for wintering migra<strong>to</strong>ry birds and <strong>to</strong> c<strong>on</strong>sult with governmental officials and scientific experts about the plan<br />

for the <strong>Poyang</strong> <strong>Lake</strong> Water C<strong>on</strong>trol Project. The team of experts was able <strong>to</strong> <strong>visit</strong> <strong>Poyang</strong> <strong>Lake</strong> and attend<br />

presentati<strong>on</strong>s and discuss the project with officials and experts who provided a large amount of informati<strong>on</strong> <strong>on</strong><br />

the ecological character of <strong>Poyang</strong> <strong>Lake</strong> covering the biology, water chemistry and hydrology in particular.<br />

应 江 西 省 林 业 厅 的 邀 请 , 湿 地 公 约 局 秘 书 处 组 建 专 家 组 ( 简 称 专 家 组 ), 目 的 是 对 鄱 阳 湖 生 态 环 境 和 现<br />

今 冬 候 鸟 基 本 状 况 进 行 考 察 , 同 时 与 政 府 部 门 及 科 学 家 就 鄱 阳 湖 水 利 枢 纽 工 程 进 行 商 讨 。 其 间 , 专 家 组<br />

实 地 考 察 了 鄱 阳 湖 , 并 与 政 府 有 关 部 门 政 府 官 员 及 相 关 科 学 家 通 过 报 告 与 讨 论 等 形 式 就 鄱 阳 湖 生 态 特<br />

征 , 尤 其 是 生 物 多 样 性 、 水 化 学 、 水 文 等 领 域 交 流 了 大 量 信 息 。<br />

In line with the obligati<strong>on</strong>s under the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong> <strong>to</strong> make wise use of and maintain the ecological<br />

character of the lake, it is emphasized that all management decisi<strong>on</strong>s should be based <strong>on</strong> the best available<br />

scientific evidence and in line with internati<strong>on</strong>al guidance for the sustainable use of wetlands and their<br />

resources (ecosystem services). This obligati<strong>on</strong> under the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong> is particularly important as it has<br />

been reported that the lake has already underg<strong>on</strong>e a change in ecological character with c<strong>on</strong>sequent changes<br />

in its widely recognized c<strong>on</strong>servati<strong>on</strong> and biodiversity values. The significance of protecting the ecological<br />

character of <strong>Poyang</strong> <strong>Lake</strong> is all the greater given the deteriorati<strong>on</strong> of many wetlands and waterbird populati<strong>on</strong>s<br />

within the middle reaches of the Yangtze River Basin, and the extraordinary importance of <strong>Poyang</strong> <strong>Lake</strong><br />

wetlands and biodiversity <strong>on</strong> a global level.<br />

湿 地 公 约 对 湿 地 合 理 利 用 及 保 护 的 相 关 义 务 和 原 则 强 调 : 所 有 的 湿 地 管 理 决 策 都 应 当 建 立 在 充 分 的 科 学<br />

论 证 和 湿 地 及 其 资 源 ( 或 生 态 系 统 服 务 功 能 ) 的 可 持 续 利 用 的 国 际 框 架 之 下 作 出 。 当 湖 泊 公 认 的 具 有 保<br />

护 意 义 和 生 物 多 样 性 价 值 的 生 态 学 特 征 被 改 变 时 , 上 述 义 务 与 原 则 就 尤 其 重 要 。 在 现 今 长 江 中 下 游 众 多<br />

湿 地 和 水 鸟 种 群 已 经 受 到 威 胁 的 情 况 下 , 鄱 阳 湖 湿 地 生 态 系 统 的 保 护 更 显 紧 迫 。 而 且 鄱 阳 湖 的 湿 地 生 物<br />

多 样 性 和 生 态 价 值 在 全 球 层 面 上 也 是 不 可 替 代 的 。<br />

A number of key recommendati<strong>on</strong>s are made below based <strong>on</strong> the c<strong>on</strong>clusi<strong>on</strong>s drawn by the <strong>Ramsar</strong> team and<br />

outlined in more detail in the body of the report:<br />

基 于 此 , 专 家 组 给 出 以 下 主 要 建 议 , 具 体 详 细 信 息 请 参 见 报 告 内 容 :<br />

<br />

<br />

Throughout their <strong>visit</strong>, the team was informed by many experts that the seas<strong>on</strong>al decline in winter water<br />

level was now starting earlier and was lasting for a l<strong>on</strong>ger period. The team, however, was unable <strong>to</strong><br />

assess the scientific data <strong>to</strong> ascertain the causes of this change, for example, whether it was due <strong>to</strong> shortterm<br />

climate variability, l<strong>on</strong>ger‐term climate change or changes <strong>to</strong> the flows al<strong>on</strong>g the Yangtze and<br />

tributary rivers <strong>to</strong> the lake. The causes of the change in winter water levels need <strong>to</strong> be investigated and<br />

placed in a climate c<strong>on</strong>text for future management.<br />

通 过 此 次 考 察 , 专 家 组 经 常 被 告 知 , 近 年 来 鄱 阳 湖 提 前 进 入 冬 季 枯 水 期 , 而 且 枯 水 期 延 长 , 水 位 偏<br />

低 。 但 是 专 家 组 目 前 还 没 有 足 够 的 科 学 数 据 来 确 定 这 种 变 化 的 原 因 。 换 句 话 说 , 还 不 能 确 定 这 是 不<br />

是 气 候 的 短 期 异 常 或 长 期 变 化 所 引 起 , 或 者 是 长 江 干 流 的 变 化 还 是 鄱 阳 湖 支 流 的 变 化 所 引 起 的 。 为<br />

了 将 来 管 理 的 需 要 , 冬 季 水 位 下 降 的 原 因 还 需 要 在 气 候 变 化 的 大 背 景 下 更 进 一 步 的 调 查 和 研 究 。<br />

Once the causes of the change in water levels are unambiguously determined, further effort should be<br />

directed <strong>to</strong>wards assessing a range of soluti<strong>on</strong>s and determining which would be the most effective<br />

without impacting <strong>on</strong> the remarkable ecological and ec<strong>on</strong>omic importance of <strong>Poyang</strong> <strong>Lake</strong>. If the<br />

ecological character of the lake is found <strong>to</strong> be changing, the <strong>Ramsar</strong> Secretariat should be formally<br />

informed as required under Article 3.2 of the C<strong>on</strong>venti<strong>on</strong>.<br />

冬 季 水 位 下 降 的 原 因 一 旦 清 晰 , 应 进 一 步 考 虑 多 种 解 决 途 径 , 从 中 择 取 最 有 效 解 决 问 题 的 方 式 , 且<br />

对 鄱 阳 湖 生 态 系 统 和 社 会 经 济 没 有 显 著 的 负 面 影 响 。 如 果 发 现 鄱 阳 湖 的 生 态 系 统 特 性 被 改 变 , 依 照<br />

湿 地 公 约 3.2 条 款 湿 地 公 约 局 应 得 到 正 式 通 知 。<br />

Given the importance of the ecosystem services provided by the lake both locally and <strong>to</strong> downstream<br />

inhabitants it could also be beneficial <strong>to</strong> introduce an incentives scheme <strong>to</strong> ensure that these services are<br />

maintained, and benefits accrued by the wider community. This strategy may include a scheme of<br />

Payment for Ecosystem Services whereby Jiangxi could receive significant development support while<br />

sustaining the widely recognized ecosystem benefits provided by the lake, many of which have regi<strong>on</strong>al or<br />

global significance.<br />

应 引 进 一 种 奖 励 机 制 , 用 于 保 持 鄱 阳 湖 为 当 地 和 下 游 提 供 的 重 要 生 态 系 统 服 务 功 能 。 江 西 省 为 了 保<br />

护 那 些 重 要 和 具 有 国 际 意 义 的 生 态 区 可 能 会 丧 失 部 分 发 展 机 会 , 但 是 可 以 通 过 生 态 补 偿 机 制 的 建 立<br />

得 到 相 应 的 资 金 补 偿 。<br />

As <strong>Poyang</strong> <strong>Lake</strong> is a unique wetland system that has evolved in resp<strong>on</strong>se <strong>to</strong> the natural seas<strong>on</strong>al<br />

fluctuati<strong>on</strong>s in water levels, changes <strong>to</strong> this natural pattern may have serious impacts <strong>on</strong> the ecology of<br />

the lake and its internati<strong>on</strong>al importance. Changing these natural fluctuati<strong>on</strong>s would impact <strong>on</strong> the<br />

fisheries, the finless porpoise, the wetland vegetati<strong>on</strong> and the waterbirds, especially the critically<br />

endangered Siberian crane. Under any management scenario, the objective should be <strong>to</strong> maintain or<br />

res<strong>to</strong>re the natural rise and fall of the water in the lake, using lake data collected over the last 50 years as<br />

a baseline. For example, the length of the winter low water period should be replicated, with lowest<br />

water levels approximating the average from the last 50 years, of 12.0 meters above sea level (Wu S<strong>on</strong>g)<br />

at Wucheng and 9.0 meters at Xingzi but with fluctuati<strong>on</strong>s within and between winters as experienced in<br />

recent decades. Changes <strong>to</strong> the natural water flow and seas<strong>on</strong>al variati<strong>on</strong> could be catastrophic for the<br />

biodiversity and ecosystem services obtained from the lake. This management objective will require a<br />

decisi<strong>on</strong> support system comprising management rules based <strong>on</strong> an appropriate hydrological model linked<br />

with a c<strong>on</strong>ceptualised ecological model of the lake.<br />

鄱 阳 湖 水 位 的 季 节 性 变 化 形 成 了 其 独 一 无 二 的 湿 地 生 态 系 统 , 改 变 这 种 自 然 状 态 无 疑 会 对 湖 泊 生 态<br />

和 其 国 际 重 要 性 造 成 严 重 的 影 响 。 改 变 这 种 自 然 的 水 位 波 动 将 严 重 影 响 鱼 类 、 江 豚 、 湿 地 植 被 和 水<br />

鸟 , 尤 其 是 濒 临 灭 绝 的 白 鹤 种 群 。 在 任 何 情 况 下 , 管 理 与 治 理 目 标 应 该 是 利 用 基 于 过 去 50 年 的<br />

( 或 更 长 的 ) 湖 泊 水 位 等 数 据 , 从 而 保 持 或 者 恢 复 湖 泊 水 位 的 自 然 消 涨 。 比 如 说 , 冬 季 枯 水 期 的 时<br />

间 尺 度 的 估 算 应 当 基 于 过 去 50 年 来 ( 或 更 长 ) 平 均 最 低 水 位 , 即 12.0 米 的 吴 城 水 位 ( 吴 淞 高 程 )<br />

和 9 米 的 星 子 水 位 ( 吴 淞 高 程 ), 而 不 是 基 于 最 近 10 年 来 年 内 冬 季 最 低 或 每 年 之 间 冬 季 最 低 水 位<br />

估 算 。 而 改 变 水 体 的 自 然 流 动 和 季 节 性 变 化 对 湖 泊 生 物 多 样 性 和 生 态 系 统 服 务 功 能 的 打 击 将 是 致 命<br />

的 ;<br />

At present, <strong>Poyang</strong> <strong>Lake</strong> receives a large input of nutrients from its catchment that may already be pushing<br />

the lake <strong>to</strong>wards a near‐irreversible change in ecological character. The c<strong>on</strong>structi<strong>on</strong> of a dam with<br />

subsequent retenti<strong>on</strong> of more water may exacerbate this situati<strong>on</strong>. It is stressed that similar changes in<br />

5


lakes and other waterbodies elsewhere are seen as near irreversible. The c<strong>on</strong>tinued inflow of nutrients<br />

in<strong>to</strong> the lake may cause a switch from a lake characterized by clear water and submerged plants (e.g.,<br />

Vallisneria spp.) <strong>to</strong> <strong>on</strong>e characterized by turbid water and high c<strong>on</strong>centrati<strong>on</strong>s of phy<strong>to</strong>plankt<strong>on</strong> with the<br />

decline or loss of those waterbirds that formerly fed <strong>on</strong> the submerged plants. This scenario may see the<br />

loss of a major feeding ground for waterbirds that are already under threat from changes elsewhere in<br />

their range. The importance of maintaining the ecological c<strong>on</strong>diti<strong>on</strong>s in <strong>Poyang</strong> <strong>Lake</strong> that support these<br />

birds must not be understated.<br />

<br />

<br />

<br />

<br />

<br />

从 生 态 特 性 上 讲 , 现 在 汇 入 湖 泊 的 大 量 营 养 物 质 已 经 很 有 可 能 将 鄱 阳 湖 推 向 难 以 逆 转 的 境 地 。 如 果<br />

再 建 造 一 个 大 坝 , 汇 集 更 多 的 水 量 将 使 这 种 情 况 更 加 恶 化 。 这 里 强 调 的 是 , 针 对 湖 泊 和 其 它 水 体 的<br />

类 似 做 法 造 成 的 无 法 挽 回 的 富 营 养 化 事 件 比 比 皆 是 。 持 续 流 入 的 营 养 物 质 将 使 清 洁 的 和 具 有 沉 水 植<br />

物 ( 如 : 苦 草 ) 的 湖 泊 向 混 浊 、 高 密 度 的 藻 类 湖 泊 演 化 , 同 时 将 导 致 依 赖 这 些 沉 水 植 物 的 鸟 类 迅 速<br />

减 少 和 消 亡 。 所 以 , 维 持 鄱 阳 湖 水 鸟 赖 以 生 存 的 生 态 环 境 非 常 重 要 。<br />

The <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong> has provided guidance <strong>to</strong> ensure that all decisi<strong>on</strong>s governing <strong>Ramsar</strong> <strong>site</strong>s are<br />

made in a balanced and transparent manner and take in<strong>to</strong> account the views of government departments,<br />

scientists and experts, and other relevant stakeholders. In line with this guidance it is recommended that a<br />

meeting should be held when the (six) expert teams that are collating further informati<strong>on</strong> <strong>on</strong> the potential<br />

c<strong>on</strong>sequences of the <strong>Poyang</strong> <strong>Lake</strong> Water C<strong>on</strong>trol Project have completed their draft reports so that their<br />

results can be presented <strong>to</strong> the wider scientific and c<strong>on</strong>servati<strong>on</strong> communities. Each of the teams could<br />

present their reports and the audience be allowed <strong>to</strong> provide comments and in particular explore the<br />

trade‐offs and synergies between management alternatives for the lake. An open scientific forum of this<br />

nature would support efforts <strong>to</strong> integrate the informati<strong>on</strong> collected from the six teams as well as provide<br />

further insight in<strong>to</strong> the complex management alternatives. Similarly, after the informati<strong>on</strong> from the six<br />

teams has been integrated, a sec<strong>on</strong>d open meeting should be held for the scientific audience <strong>to</strong> comment<br />

<strong>on</strong> the final report.<br />

湿 地 公 约 提 供 的 指 南 希 望 所 有 的 国 际 重 要 湿 地 的 管 理 决 策 应 建 立 在 公 平 透 明 的 基 础 上 , 要 充 分 考 虑<br />

政 府 部 门 、 科 学 界 、 专 家 及 其 它 利 益 相 关 者 的 意 见 。 根 据 这 一 指 南 , 湿 地 公 约 局 建 议 6 大 课 题 组 经<br />

信 息 交 流 及 完 成 鄱 阳 湖 水 利 枢 纽 工 程 潜 在 影 响 研 究 后 召 开 一 个 会 议 , 每 个 课 题 组 的 研 究 成 果 能 够 得<br />

到 科 学 界 和 保 护 界 的 广 泛 建 议 和 交 流 , 以 便 得 到 更 多 湖 泊 治 理 的 替 代 方 案 。 开 放 的 科 学 论 坛 将 有 助<br />

于 6 大 课 题 整 合 和 交 流 信 息 。 同 样 的 , 当 6 大 课 题 研 究 结 果 整 合 后 应 召 开 第 二 次 公 开 会 议 , 为 最 终<br />

报 告 征 求 更 多 建 议 。<br />

<strong>Poyang</strong> <strong>Lake</strong> is affected by a range of different stakeholders with different interests. As the ec<strong>on</strong>omic and<br />

populati<strong>on</strong> pressures around the lake are growing, especially with the development of the new <strong>Poyang</strong><br />

<strong>Lake</strong> Eco‐Ec<strong>on</strong>omic Development Z<strong>on</strong>e, internati<strong>on</strong>al experience shows that it would be important <strong>to</strong> form<br />

an independent and broad‐based management committee that would be resp<strong>on</strong>sible for the l<strong>on</strong>g‐term<br />

management of <strong>Poyang</strong> <strong>Lake</strong> and its river basin. The team stressed the importance of managing the<br />

system and its water resources at a watershed level. There are many examples of such river basin<br />

management committees from around the world that could be studied and used <strong>to</strong> develop a model for<br />

<strong>Poyang</strong>. It is also recommended that an independent technical advisory committee is established <strong>to</strong><br />

support the management committee. The advisory committee could also benefit from internati<strong>on</strong>al<br />

expertise.<br />

鄱 阳 湖 涉 及 来 自 不 同 利 益 相 关 者 的 利 益 影 响 , 环 湖 经 济 发 展 和 人 口 的 压 力 越 来 越 大 , 尤 其 是 新 的 鄱<br />

The <strong>Ramsar</strong> Secretariat is able <strong>to</strong> provide further advice <strong>on</strong> the reporting requirements under the<br />

C<strong>on</strong>venti<strong>on</strong> and the availability of technical guidance for the sustainable use and management of<br />

wetlands. It is also well positi<strong>on</strong>ed <strong>to</strong> advise <strong>on</strong> processes <strong>to</strong> ensure that the large informati<strong>on</strong> resource<br />

already available and being collated is treated in an integrated manner <strong>to</strong> further describe, assess and<br />

m<strong>on</strong>i<strong>to</strong>r the ecological character of the lake in line with internati<strong>on</strong>al best practice.<br />

1. POYANG LAKE, P.R. CHINA (RAMSAR SITE N° 550)<br />

1.1 The <strong>Poyang</strong> <strong>Lake</strong> envir<strong>on</strong>ment<br />

<strong>Poyang</strong> <strong>Lake</strong> is <strong>on</strong>e of the largest freshwater wetlands in Asia with an area of approximately 4,000 km 2 during<br />

summer high water (Shankman et al. 2006; Figure 1). <strong>Poyang</strong> and D<strong>on</strong>gting are the <strong>on</strong>ly sizable lakes in the mid<br />

Yangtze River Basin that retain a natural c<strong>on</strong>necti<strong>on</strong> <strong>to</strong> the river (all other lakes are separated by sluice gates<br />

and embankments). <strong>Poyang</strong> <strong>Lake</strong> is a dynamic wetland system where water depths are deep during the<br />

summer rainy seas<strong>on</strong> and shallow during the winter dry seas<strong>on</strong>, with differences as great as 13 m within a year.<br />

Figure 1. <strong>Poyang</strong> <strong>Lake</strong> at high water (left) and low water (right) overlaid with study area for research by PLNR and Internati<strong>on</strong>al<br />

Crane Foundati<strong>on</strong> <strong>on</strong> waterbirds, water levels, and aquatic food plants, and with the locati<strong>on</strong> of Nanjishan Nature<br />

Reserve. Adapted from Barzen et al. (2009).<br />

The watershed of the lake (144,000 km 2 ) is entirely encompassed within and covers 97% of Jiangxi Province,<br />

with five main tributaries draining in<strong>to</strong> the lake (the Gan, Xiu, Fu, Xing and Rao Rivers). Mean annual runoff<br />

from the lake in<strong>to</strong> the Yangtze is 143.6 Bm 3 (i.e., 15% of the <strong>to</strong>tal Yangtze flow). <strong>Poyang</strong> has a seas<strong>on</strong>al,<br />

reverse‐flow system which greatly c<strong>on</strong>tributes <strong>to</strong> the complexity of its yearly hydrological variati<strong>on</strong>. Typically,<br />

the five tributary rivers flood during spring and early summer with water levels peaking in the summer.<br />

Outflow from the lake is c<strong>on</strong>trolled by hydraulic head (i.e., the difference in water‐levels) between the lake and<br />

8


the Yangtze River. Sometimes, when the Yangtze is in flood in late summer, water levels in the river are<br />

greater than they are in the lake and so water flows from the Yangtze in<strong>to</strong> the lake. This phenomen<strong>on</strong> adds <strong>to</strong><br />

the hydrological complexity and variability of the system (Shankman and Liang 2003). Variati<strong>on</strong> in water levels,<br />

both within and am<strong>on</strong>g years, directly c<strong>on</strong>tributes <strong>to</strong> the large biomass of plant life (Li et al. 2004), and<br />

provides a wide range of foraging opti<strong>on</strong>s for many waterbird species (Cao et al. 2008, Barzen unpublished<br />

data).<br />

<strong>Poyang</strong> <strong>Lake</strong> is characterized by a broad, flat landscape dominated by gradual slopes typical of floodplains.<br />

Many sub‐lakes occur in the southern and western regi<strong>on</strong>s of the lake after the water level falls and fragments<br />

the remaining water in<strong>to</strong> separate isolated parts. At these times, the sub‐lakes are c<strong>on</strong>nected <strong>to</strong> <strong>Poyang</strong> <strong>Lake</strong><br />

<strong>on</strong>ly by small channels either natural or man‐made. The sub‐lakes are usually rec<strong>on</strong>nected by sheet flows of<br />

water during summer floods.<br />

Biological productivity within these wetlands is often c<strong>on</strong>centrated in areas where slopes are shallow because<br />

relatively flat gradients allow for the accumulati<strong>on</strong> and presence of water over time. Steeper slopes allow for<br />

quicker run‐off and limits the water <strong>to</strong> a relatively narrow band around the edge of the lake, thereby reducing<br />

habitat availability for wetland plants and animals. Due <strong>to</strong> the overall flat <strong>to</strong>pography, the wetlands and<br />

waterbirds are highly sensitive <strong>to</strong> changes in water levels.<br />

<strong>Poyang</strong> <strong>Lake</strong> has by far the largest number of wintering waterbirds of any wetland in East Asia, with over<br />

400,000 present in many winters (see Barter et al. 2004, Barter et al. 2005, Li et al. 2004, Ji et al. 2007). The<br />

lake supports almost all the world populati<strong>on</strong> of the critically endangered Siberian crane Grus leucogeranus and<br />

the endangered oriental s<strong>to</strong>rk Cic<strong>on</strong>ia boyciana, and substantial numbers of several other threatened species.<br />

It also supports <strong>on</strong>e of the largest surviving populati<strong>on</strong>s of finless porpoise Neophocaena phocaenoides<br />

asiaeorientalis, and a large diversity of fish species.<br />

The lake also has immense ec<strong>on</strong>omic importance for Jiangxi Province, and <strong>China</strong>’s State Council recently<br />

approved a <strong>Poyang</strong> <strong>Lake</strong> Eco‐ec<strong>on</strong>omic Development Z<strong>on</strong>e that includes 38 counties surrounding the lake and<br />

over 28 milli<strong>on</strong> people. The water and wetland resources have major ec<strong>on</strong>omic importance for fisheries,<br />

transport, and agriculture. Aside from these ec<strong>on</strong>omic benefits, the large wetlands provide highly important<br />

ecosystem services such as water s<strong>to</strong>rage, flood c<strong>on</strong>trol, and ameliorati<strong>on</strong> of water quality. Due <strong>to</strong> the unique<br />

ecology and its nati<strong>on</strong>al and global biodiversity significance, 19 nature reserves have been established in and<br />

around the lake, including 14 primarily for migra<strong>to</strong>ry waterbirds and their wetland habitats and 5 for aquatic<br />

animals.<br />

1.2 <strong>Poyang</strong> <strong>Lake</strong> <strong>Ramsar</strong> Site<br />

<strong>Poyang</strong> <strong>Lake</strong> Nati<strong>on</strong>al Nature Reserve (PLNR) is the most important of the reserves for cranes and many other<br />

waterbirds in and around <strong>Poyang</strong> <strong>Lake</strong>. It was established in 1983 and designated by the Chinese Government<br />

as a <strong>Ramsar</strong> Site in 1992. PLNR covers an area of 22,400 hectares in the northwest corner of the lake basin,<br />

where the Xiu and Gan Rivers join before entering the main <strong>Poyang</strong> <strong>Lake</strong>. In autumn, as lake levels drop and<br />

vast mudflats are exposed, nine sub‐lakes form and comprise the primary habitat within the reserve for<br />

waterbirds. Of these lakes, two (Da Cha Hu and Bang Hu) have direct c<strong>on</strong>necti<strong>on</strong> <strong>to</strong> the main lake even during<br />

winter, while the other seven are separated for the winter m<strong>on</strong>ths; thus their water levels differ from the main<br />

lake. These seven drain via channels that are c<strong>on</strong>trolled by sluice gates <strong>to</strong> regulate the outflow of water in a<br />

manner that enhances the annual fish catch.<br />

While almost all of the <strong>Poyang</strong> <strong>Lake</strong> Basin is utilized by people, PLNR has secured the use rights <strong>to</strong> five of the<br />

nine lakes: Da Hu Chi, Sha Hu, Chang Hu Chi, Xiang Hu, and Zhu Shi Hu (Figure 2). For these five lakes, the<br />

reserve is thus able <strong>to</strong> regulate water releases, fishing, and other human activity such as lives<strong>to</strong>ck grazing that<br />

affect waterbirds. Of these lakes, Da Hu Chi is the most important for waterbirds and often provides foraging<br />

habitat for cranes, s<strong>to</strong>rks, geese, and swans.<br />

represents the average low water elevati<strong>on</strong> (11.98 m Wu S<strong>on</strong>g) in <strong>Poyang</strong> <strong>Lake</strong>. The red boundary is the study area<br />

included within the Digital Elevati<strong>on</strong> Map. Adapted from Barzen et al. (2009).<br />

PLNR headquarters are located in Nanchang while three m<strong>on</strong>i<strong>to</strong>ring/educati<strong>on</strong> stati<strong>on</strong>s exist within the<br />

reserve. A further seven stati<strong>on</strong>s are being developed in other parts of the lake. PLNR covers <strong>on</strong>ly 5% of the<br />

wetlands at <strong>Poyang</strong>. While the nine sub‐lakes within PLNR represent the most heavily used habitat by birds,<br />

utilizati<strong>on</strong> patterns by wintering waterbirds are excepti<strong>on</strong>ally dynamic and can shift rapidly <strong>to</strong> reflect changing<br />

c<strong>on</strong>diti<strong>on</strong>s within the lake basin with regards <strong>to</strong> food accessibility and human disturbance. Often these<br />

waterbirds are found outside of the boundaries of PLNR and other protected areas across the lake basin.<br />

During times of drought, PLNR may have practically no water birds. The network of reserves therefore serves<br />

<strong>to</strong> protect a wide range of habitats with water and vegetati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s that fluctuate through space and<br />

time. The shifting patchwork of resources that exist across the vast extent of <strong>Poyang</strong> <strong>Lake</strong>’s shallow water<br />

wetlands has c<strong>on</strong>sistently provided sufficient foraging and roosting habitat for the large numbers of birds with<br />

highly diverse requirements even in periods of extreme flood and extreme drought, <strong>on</strong>ly possible because of<br />

<strong>Poyang</strong>’s vast size and shifting c<strong>on</strong>diti<strong>on</strong>s during the winter m<strong>on</strong>ths. Due <strong>to</strong> the hydrologic c<strong>on</strong>necti<strong>on</strong>s, and<br />

frequent movements of waterbirds, the c<strong>on</strong>servati<strong>on</strong> values of PLNR are dependent <strong>on</strong> its c<strong>on</strong>necti<strong>on</strong>s <strong>to</strong> the<br />

lake as a whole and <strong>to</strong> the wider basin.<br />

2. BACKGROUND INFORMATION<br />

2.1 Problems facing the <strong>site</strong><br />

In recent years, it is claimed that <strong>Poyang</strong> <strong>Lake</strong> has been shrinking with observable declines in the winter lake<br />

area and volume due <strong>to</strong> the water levels decreasing earlier in the year, and lasting for a l<strong>on</strong>ger period than in<br />

the past. This is said <strong>to</strong> cause:<br />

difficulties for urban and rural areas around the lake having access <strong>to</strong> water, especially for irrigati<strong>on</strong>, but<br />

also domestic supply. For example it is estimated that 250,000 people had problems getting drinking<br />

water for 3 m<strong>on</strong>ths in the winter of 2006;<br />

impacts <strong>on</strong> the wetland biodiversity of the lake, especially aquatic plants and waterbirds. It is claimed that<br />

water‐bird number have dropped significantly;<br />

reducti<strong>on</strong> in the navigability of the channels in the lake for shipping because they are <strong>to</strong>o shallow. For<br />

example during the winter of 2007 shipping was significantly affected;<br />

depleti<strong>on</strong> of the fishery resources, and;<br />

deteriorati<strong>on</strong> in the water quality of the lake due <strong>to</strong> its small size.<br />

The low water levels also expose small grassy islands within the lake as well as shoreline suitable for the water<br />

snails that are host for the para<strong>site</strong> that causes schis<strong>to</strong>somiasis, a disease that is prevalent am<strong>on</strong>g people living<br />

around the lake.<br />

2.2 Measure proposed by the Jiangxi Provincial Government<br />

In resp<strong>on</strong>se <strong>to</strong> the problem of low water levels in winter, the Jiangxi Provincial government has proposed<br />

building a 2.8 km l<strong>on</strong>g dam with sluice gates across the narrowest part of the channel linking the lake and the<br />

Yangtze River (Figure 1).<br />

The dam would be in Xingzi County, some 27 km from where the waters from <strong>Poyang</strong> <strong>Lake</strong> meet the Yangtze<br />

River. The exact design of the dam has yet <strong>to</strong> be decided. Similarly, the manner in which water will be released<br />

through the dam has not been determined. However, it is intended that the dam will maintain predetermined<br />

seas<strong>on</strong>al water levels in the lake at different times of year in order <strong>to</strong> meet the needs of the different<br />

stakeholders as well as <strong>to</strong> maintain the ecological value of the lake. Basically, the sluice gates would be open<br />

during the wet seas<strong>on</strong> and allow the water levels in the lake <strong>to</strong> rise, but then the sluice gates would be closed<br />

during the winter period and water slowly released in a c<strong>on</strong>trolled manner.<br />

The dam is intended <strong>to</strong> provide multiple benefits including:<br />

To maintain a set area and volume of water in the lake so as <strong>to</strong> maintain the aquatic envir<strong>on</strong>ment of<br />

<strong>Poyang</strong> <strong>Lake</strong>;<br />

To allow comprehensive development and management of the water resources for irrigati<strong>on</strong>, water<br />

supply, navigati<strong>on</strong>, <strong>to</strong>urism, fishery, etc.;<br />

To c<strong>on</strong>tribute <strong>to</strong> the c<strong>on</strong>servati<strong>on</strong> of the protected areas within <strong>Poyang</strong> <strong>Lake</strong> and the wetland biodiversity<br />

that they support; and<br />

To aid in the c<strong>on</strong>trol and eliminati<strong>on</strong> of schis<strong>to</strong>somiasis in the lake regi<strong>on</strong>.<br />

In this way, the dam would be able both <strong>to</strong> maintain the ecological value of the lake as well as promote<br />

sustainable ec<strong>on</strong>omic development in the <strong>Poyang</strong> <strong>Lake</strong> regi<strong>on</strong>. Ec<strong>on</strong>omic development is an important issue in<br />

Jiangxi Province as it is <strong>on</strong>e of the least developed provinces in <strong>China</strong>. As a result, the Provincial Government<br />

proposed the development of the 51,200 km 2 <strong>Poyang</strong> <strong>Lake</strong> Eco‐ec<strong>on</strong>omic Development Z<strong>on</strong>e around the lake,<br />

11


with the dam as <strong>on</strong>e of the project elements. The Central Government approved the Eco‐ec<strong>on</strong>omic Z<strong>on</strong>e in<br />

December 2009 but did not approve the dam. Instead, they asked that further scientific assessment be carried<br />

out <strong>on</strong> the likely impacts of the dam. As a result, Jiangxi Province requested scientists within the Chinese<br />

Academy of Sciences and Chinese Academy of Water Resources <strong>to</strong> form six teams, each <strong>to</strong> investigate <strong>on</strong>e of<br />

the six key issues related <strong>to</strong> the proposed dam. These <strong>to</strong>pics were related <strong>to</strong> the effects of the dam <strong>on</strong>:<br />

Sediment depositi<strong>on</strong> and its countermeasures;<br />

Flood c<strong>on</strong>trol and its countermeasures;<br />

Water quality and its countermeasures;<br />

Wetland and migra<strong>to</strong>ry birds and its countermeasures;<br />

Aquatic life resources in <strong>Poyang</strong> <strong>Lake</strong> and its countermeasures;<br />

The linkage between <strong>Poyang</strong> <strong>Lake</strong> and the Yangtze River.<br />

The objective of these expert scientific teams is <strong>to</strong> analyze potential negative impacts of the dam, propose<br />

ways <strong>to</strong> reduce or mitigate these impacts and then provide scientifically based recommendati<strong>on</strong>s whether the<br />

dam should go ahead. The six teams are expected <strong>to</strong> release the first drafts of their reports at the end of April<br />

2010.<br />

3. INTERNATIONAL AND NATIONAL OBLIGATIONS<br />

3.1 Obligati<strong>on</strong>s under the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong> <strong>on</strong> Wetlands<br />

The Chinese government joined the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong> <strong>on</strong> Wetlands in 1992 and as part of their accessi<strong>on</strong><br />

process, listed <strong>Poyang</strong> <strong>Lake</strong> Nati<strong>on</strong>al Nature Reserve as <strong>on</strong>e of their first Wetlands of Internati<strong>on</strong>al Importance<br />

(<strong>Ramsar</strong> <strong>site</strong>) in the same year. The justificati<strong>on</strong>s for listing the <strong>Poyang</strong> <strong>Lake</strong> NNR as a <strong>Ramsar</strong> <strong>site</strong> included:<br />

the largest fresh water lake in <strong>China</strong> in near‐natural state (Criteri<strong>on</strong> 1a);<br />

a good example of natural lake and alluvial floodplain (Criteri<strong>on</strong> 1c);<br />

supports large numbers of wintering waterfowl including several endangered species and important fauna<br />

and flora communities (Criteri<strong>on</strong> 2a).<br />

supports over 100,000 wintering waterfowl (Criteri<strong>on</strong> 3a);<br />

supports nearly 3,000 Siberian White Cranes (Grus leucogeranus), accounting for 95% of the world’s <strong>to</strong>tal<br />

(Criteri<strong>on</strong> 3c).<br />

As a C<strong>on</strong>tracting Party <strong>to</strong> the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong>, the government has the following obligati<strong>on</strong>s:<br />

<strong>to</strong> maintain the ecological character of their <strong>Ramsar</strong> <strong>site</strong>s (Article 3.1; Resoluti<strong>on</strong> VIII.8);<br />

<strong>to</strong> inform the Secretariat if the ecological character of any <strong>Ramsar</strong> <strong>site</strong> has changed, is changing or is likely<br />

<strong>to</strong> change as the result of technological developments, polluti<strong>on</strong> or other human interference (Article 3.2);<br />

VII.16 and VIII.9); and<br />

<strong>to</strong> undertake relevant forms of community participati<strong>on</strong> (Recommendati<strong>on</strong> 6.3; Resoluti<strong>on</strong> VII.8).<br />

12


3.2 Obligati<strong>on</strong>s under Chinese nati<strong>on</strong>al regulati<strong>on</strong>s<br />

<strong>Poyang</strong> <strong>Lake</strong> wetland and its nati<strong>on</strong>al nature reserve are defined as a nati<strong>on</strong>ally and internati<strong>on</strong>ally important<br />

wetland with internati<strong>on</strong>al key species of wintering birds within the ‘Nati<strong>on</strong>al Wetland C<strong>on</strong>servati<strong>on</strong> Acti<strong>on</strong><br />

Plan’ enacted in 1999 by the State Forestry Administrati<strong>on</strong>, the <strong>China</strong> State Wetland Authority. Specific<br />

nati<strong>on</strong>al wetland legislati<strong>on</strong> is planned but not yet ready. In 2004, the Jiangxi Provincial Government issued the<br />

‘<strong>Poyang</strong> <strong>Lake</strong> Wetland C<strong>on</strong>servati<strong>on</strong> Regulati<strong>on</strong>’ which further defined the importance of the wetland and its<br />

ecosystem. In additi<strong>on</strong>, the <strong>Poyang</strong> <strong>Lake</strong> Nati<strong>on</strong>al Nature Reserve and Nanjishan Nati<strong>on</strong>al Nature Reserve are<br />

also under the protecti<strong>on</strong> of the ‘<strong>China</strong> Nati<strong>on</strong>al Nature Reserve Regulati<strong>on</strong>’.<br />

The obligati<strong>on</strong>s from the legislati<strong>on</strong> are listed as follows (An<strong>on</strong>ymous 2004):<br />

a. Clear definiti<strong>on</strong> of the wetland and its resources, with the definiti<strong>on</strong> based <strong>on</strong> that adopted by the <strong>Ramsar</strong><br />

C<strong>on</strong>venti<strong>on</strong>;<br />

b. Ecosystem c<strong>on</strong>servati<strong>on</strong> first, and development sec<strong>on</strong>d;<br />

c. The c<strong>on</strong>servati<strong>on</strong> of the wetland should be included in the overall development plan of the province;<br />

d. The wetland c<strong>on</strong>servati<strong>on</strong> plan needs <strong>to</strong> approved by the provincial government;<br />

e. The provincial government should approve the establishment of nature reserves <strong>to</strong> support: endangered<br />

species; habitats for nati<strong>on</strong>ally important migra<strong>to</strong>ry species; main spawning areas for important fish<br />

species; and high c<strong>on</strong>centrati<strong>on</strong>s of wetland wildlife; and<br />

f. It is obliga<strong>to</strong>ry for any engineering projects in the wetland area <strong>to</strong> undergo a strict envir<strong>on</strong>mental<br />

assessment.<br />

4. VISIT TO POYANG LAKE BY THE RAMSAR TEAM<br />

4.1 Involvement of the <strong>Ramsar</strong> Secretariat and the formati<strong>on</strong> of an expert team <strong>to</strong><br />

<strong>visit</strong> <strong>Poyang</strong> <strong>Lake</strong><br />

On 21 April 2009, the <strong>Ramsar</strong> Secretariat wrote <strong>to</strong> the Permanent Representative of the P.R. <strong>China</strong> <strong>to</strong> the<br />

United Nati<strong>on</strong>s Office in Geneva requesting more informati<strong>on</strong> about the dam that was being proposed <strong>to</strong> be<br />

built across the outlet of <strong>Poyang</strong> <strong>Lake</strong>. On 2 July 2009, the State Forestry Administrati<strong>on</strong> (SFA) replied saying<br />

that such a proposal would first require a comprehensive and scientific evaluati<strong>on</strong>, including a cost‐benefit<br />

analysis and an envir<strong>on</strong>mental impact assessment. The proposal would then have <strong>to</strong> be reviewed by the central<br />

government which would then make a decisi<strong>on</strong> <strong>on</strong> whether <strong>to</strong> approve the plan or not.<br />

In January 2010, the Secretariat was c<strong>on</strong>tacted informally by SFA <strong>on</strong> behalf of the Jiangxi Province Forestry<br />

Department, with a request <strong>to</strong> form a team with experts from IUCN and WWF <strong>to</strong> <strong>visit</strong> <strong>Poyang</strong> <strong>Lake</strong>.<br />

On 11 March 2010, the Secretariat received a formal request from the Jiangxi Province Forestry Department via<br />

SFA, <strong>to</strong> form a team of experts with the aim of ‘…studying the ecological envir<strong>on</strong>ment of <strong>Poyang</strong> <strong>Lake</strong> and<br />

current situati<strong>on</strong> of wintering migra<strong>to</strong>ry birds, communicating some problems and c<strong>on</strong>sulting opini<strong>on</strong>s and<br />

advice <strong>on</strong> the plan of <strong>Poyang</strong> <strong>Lake</strong> Water C<strong>on</strong>trol Project with the experts.’ A joint team was then quickly<br />

formed and <strong>visit</strong>ed <strong>China</strong> <strong>to</strong> hold meetings with government officials and scientific experts, as well as <strong>to</strong> make<br />

<strong>site</strong> <strong>visit</strong>s <strong>to</strong> <strong>Poyang</strong> <strong>Lake</strong> according <strong>to</strong> the schedule given in Appendix 1.<br />

4.2 Meeting with the State Forestry Administrati<strong>on</strong> (SFA)<br />

During the meeting with the Wetlands Center of SFA <strong>on</strong> the morning of 13 April, SFA officials explained that the<br />

proposed dam has attracted much attenti<strong>on</strong> from government bodies, provinces and cities from the middle<br />

13


and lower stretches of the Yangtzse River, scientific experts, as well as from internati<strong>on</strong>al organizati<strong>on</strong>s. As a<br />

result, SFA held regular communicati<strong>on</strong>s with Jiangxi Province. Jiangxi was interested in exchanging ideas and<br />

holding discussi<strong>on</strong>s with internati<strong>on</strong>al experts about the c<strong>on</strong>structi<strong>on</strong> of the dam. Therefore, SFA agreed <strong>to</strong><br />

c<strong>on</strong>tact the Secretariat <strong>to</strong> seek their assistance in forming a team of experts <strong>to</strong> <strong>visit</strong> <strong>Poyang</strong> <strong>Lake</strong>. Overall, SFA<br />

said that they have placed a lot of attenti<strong>on</strong> <strong>on</strong> the proposed dam and have requested Jiangxi Province <strong>to</strong><br />

c<strong>on</strong>duct a sound and detailed assessment of the project – whether <strong>to</strong> build the structure or not and if so, how<br />

<strong>to</strong> best build the structure.<br />

4.3 Meeting with Chinese Academy of Sciences (CAS)<br />

A meeting was organized at the Institute of Geographic Sciences and Natural Resources Research, Chinese<br />

Academy of Sciences with <strong>on</strong>e of the six teams that have been established by the Jiangxi Provincial government<br />

<strong>to</strong> investigate the effects of the proposed dam. This team was charged with examining impacts <strong>on</strong> the<br />

wetlands and migra<strong>to</strong>ry birds.<br />

4.4 Meeting with the Governor of Jiangxi Province<br />

In the afterno<strong>on</strong> of 14 April, Mr. Wu Xinxi<strong>on</strong>g, the Governor of Jiangxi Province, and other provincial leaders<br />

met with the <strong>Ramsar</strong> group for around 45 minutes and then had dinner with them afterwards. The Governor<br />

showed his awareness of the ecological importance of <strong>Poyang</strong> <strong>Lake</strong> and outlined the steps the Government had<br />

taken <strong>to</strong> promote envir<strong>on</strong>mental protecti<strong>on</strong> in the Province. He also explained the need for promoting<br />

sustainable development in order <strong>to</strong> lift the people <strong>to</strong> a higher ec<strong>on</strong>omic standard. A highly important part of<br />

this effort was the development of the <strong>Poyang</strong> <strong>Lake</strong> Eco‐ec<strong>on</strong>omic Development Z<strong>on</strong>e.<br />

4.5 Meeting with provincial government departments<br />

On the afterno<strong>on</strong> of Thursday 15 April, a meeting was organized for the team with representatives from<br />

relevant Jiangxi Provincial government departments that have a role in the c<strong>on</strong>servati<strong>on</strong> and management of<br />

<strong>Poyang</strong> <strong>Lake</strong>. The aim was <strong>to</strong> exchange views <strong>on</strong> the problems facing <strong>Poyang</strong> <strong>Lake</strong> and <strong>to</strong> present soluti<strong>on</strong>s <strong>to</strong><br />

those problems. A list of the participants from the Jiangxi Provincial government is given in Appendix 2. Due <strong>to</strong><br />

insufficient time for the presentati<strong>on</strong>s and discussi<strong>on</strong>s, it was decided <strong>to</strong> c<strong>on</strong>tinue the meeting the following<br />

morning (Friday, 16 April) instead of <strong>visit</strong>ing the Nanjishan Nati<strong>on</strong>al Nature Reserve. Below is a summary of our<br />

understanding of the presentati<strong>on</strong>s from each of the departments.<br />

Jiangxi Province Water Resource Department: A detailed presentati<strong>on</strong> was given <strong>on</strong> the geography of <strong>Poyang</strong><br />

<strong>Lake</strong>, the envir<strong>on</strong>mental problems that it faces and the proposed soluti<strong>on</strong> through the c<strong>on</strong>structi<strong>on</strong> of a water<br />

c<strong>on</strong>trol structure (dam/sluice) across the mouth of <strong>Poyang</strong> <strong>Lake</strong>.<br />

Jiangxi Province Reform and Development Department: In December 2009, the Eco‐Ec<strong>on</strong>omic Z<strong>on</strong>e (EEZ)<br />

project around <strong>Poyang</strong> <strong>Lake</strong> was approved by Central Government and has since become part of the nati<strong>on</strong>al<br />

development strategy. The proposed Water C<strong>on</strong>servancy Project is an important part of the EEZ in promoting<br />

sustainable development. Without it, there will be negative impacts <strong>on</strong> the envir<strong>on</strong>ment and possibly the EEZ.<br />

Jiangxi Province Transportati<strong>on</strong> Department: There is a trend for the barges and other boats using <strong>Poyang</strong> <strong>Lake</strong><br />

<strong>to</strong> be increasing in size. However, the lake is setting limits <strong>to</strong> this growth due <strong>to</strong> the low water levels in the five<br />

rivers flowing in<strong>to</strong> the lake and in the channels of the lake itself during the winter seas<strong>on</strong>. The Water<br />

C<strong>on</strong>servancy Project will therefore greatly improve the navigability of the lake by increasing the water depth.<br />

This project will allow ships <strong>to</strong> reach all the counties around the lake and the c<strong>on</strong>structi<strong>on</strong> of larger harbors.<br />

Jiangxi Province Envir<strong>on</strong>mental Protecti<strong>on</strong> Department: A recent study has shown that <strong>Poyang</strong> <strong>Lake</strong> has <strong>on</strong>e of<br />

the best ecological c<strong>on</strong>diti<strong>on</strong>s and water quality in <strong>China</strong>. However, the lake is now facing ecological difficulties<br />

with recent ec<strong>on</strong>omic development. In order <strong>to</strong> maintain the lake’s ecological character, it is important <strong>to</strong><br />

14


maintain the natural fluctuati<strong>on</strong>s in water levels that will be beneficial for water plants, fish migrati<strong>on</strong>,<br />

irrigati<strong>on</strong>, food producti<strong>on</strong> and flood c<strong>on</strong>trol.<br />

Jiangxi Province Agriculture Department: <strong>Poyang</strong> <strong>Lake</strong> supports some 100,000 fishermen and 18,000 fishing<br />

boats. Climate change and other fac<strong>to</strong>rs have had a negative impact <strong>on</strong> the fishing industry and researchers<br />

from the CAS have found that the soluti<strong>on</strong> would be <strong>to</strong> increase the water level and area of the lake as would<br />

occur under the proposed Water C<strong>on</strong>servancy Project. This project would also improve c<strong>on</strong>diti<strong>on</strong>s for the<br />

finless porpoise. However, the project may have negative impacts by blocking fish migrati<strong>on</strong> and so lead <strong>to</strong> a<br />

change in the fish community but this may not be <strong>to</strong>o great. Similarly, the migra<strong>to</strong>ry route for the porpoises<br />

may be blocked, leading <strong>to</strong> genetic impacts <strong>on</strong> the populati<strong>on</strong>.<br />

Jiangxi Province Health Department: Some 4.7 milli<strong>on</strong> people living in the 38 counties around <strong>Poyang</strong> <strong>Lake</strong> are<br />

facing a serious problem with schis<strong>to</strong>somiasis. Freshwater snails are the main vec<strong>to</strong>r for the para<strong>site</strong> that<br />

causes the disease in humans, living in the edges of the lake and the grassy islands in the lake which are grazed<br />

by lives<strong>to</strong>ck. The snails can be eliminated from the islands if the lake water level were <strong>to</strong> be raised above 16<br />

meters for an eight m<strong>on</strong>th period, as the islands would then be flooded. Maintaining such a high water level is<br />

thus important for c<strong>on</strong>trol of the disease.<br />

Jiangxi Province Forestry Department: Some 15 protected areas have been established around <strong>Poyang</strong> <strong>Lake</strong> for<br />

waterbirds. Two of these are important <strong>on</strong> a nati<strong>on</strong>al level, two <strong>on</strong> a provincial level, and 10 <strong>on</strong> a county level.<br />

The <strong>Poyang</strong> <strong>Lake</strong> Nati<strong>on</strong>al Nature Reserve receives financial support from the provincial, nati<strong>on</strong>al and<br />

internati<strong>on</strong>al levels <strong>to</strong> c<strong>on</strong>duct a range of c<strong>on</strong>servati<strong>on</strong>, management and community based activities. There is<br />

a need <strong>to</strong> balance c<strong>on</strong>servati<strong>on</strong> and development for future generati<strong>on</strong>s. The proposed hydraulic project<br />

should be more c<strong>on</strong>ducive for biodiversity by carrying out dynamic management of water levels <strong>to</strong> avoid water<br />

shortages in all seas<strong>on</strong>s.<br />

5. ISSUES CONSIDERED BY THE TEAM<br />

5.1 Informati<strong>on</strong> needs<br />

Officials from Jiangxi Province provided () informati<strong>on</strong> <strong>on</strong> the ecological character of <strong>Poyang</strong> <strong>Lake</strong> covering the<br />

biology, water chemistry and hydrology in particular. The informati<strong>on</strong> was largely provided during<br />

presentati<strong>on</strong>s and discussi<strong>on</strong>s with scientists and officials from the Province and indicated both the extent of<br />

available knowledge and the complexity of the lake ecosystem. Gaps in the informati<strong>on</strong> provided are expected<br />

<strong>to</strong> be further addressed in the six projects commissi<strong>on</strong>ed by the Province and referred <strong>to</strong> in Secti<strong>on</strong> 4.3 of this<br />

report. We were able <strong>to</strong> meet with the researchers from the Geographical Sciences and Natural Resources<br />

Research Institute in Beijing (an institute of the Chinese Academy of Sciences) who are undertaking the<br />

investigati<strong>on</strong>s in<strong>to</strong> the wetland and waterbirds. These discussi<strong>on</strong>s provided an introducti<strong>on</strong> <strong>to</strong> the informati<strong>on</strong><br />

being collated in their reports <strong>on</strong> the effects of the dam <strong>on</strong> the lake system and introduced some key issues<br />

that warrant further attenti<strong>on</strong>. However, the team did not see much of the scientific evidence that supports<br />

many of the statements made about the lake.<br />

Much of the case in support of c<strong>on</strong>structing a water regulati<strong>on</strong> system (with a dam and sluice gates seemingly<br />

the favoured opti<strong>on</strong>) across the outlet of the lake <strong>to</strong> the Yangtze River is based <strong>on</strong> the percepti<strong>on</strong> of recent<br />

extreme drying of the lake during the dry, winter seas<strong>on</strong>. However, the limited l<strong>on</strong>g‐term data provided <strong>to</strong> us<br />

(see Figures 3 and 4) suggest that the lowest water levels in recent winters are comparable <strong>to</strong> other periods in<br />

the recent past, although the durati<strong>on</strong> of the low water period may have changed. Figure 3 presents a time<br />

series (1956‐2009) of measured m<strong>on</strong>thly average water levels in <strong>Poyang</strong> <strong>Lake</strong> close <strong>to</strong> its c<strong>on</strong>fluence with the<br />

Yangtze River. Figure 4 shows a similar time series of flows from the lake in<strong>to</strong> the Yangtze River. The figures<br />

illustrate both the seas<strong>on</strong>al and the inter‐annual variability in water‐levels and flows. <strong>Lake</strong> water‐levels<br />

15


typically range from a minimum of 7‐9 m in winter <strong>to</strong> a maximum of approximately 18‐21 m in summer. Flow<br />

typically varies from less than 1,000 m 3 s ‐1 in winter <strong>to</strong> in excess of 10,000 m 3 s ‐1 (occasi<strong>on</strong>ally > 13,000 m 3 s ‐1 ) in<br />

summer. Intermittent negative values in Figure 4 indicate flows from the Yangtze in<strong>to</strong> the lake. Both graphs<br />

also suggest l<strong>on</strong>ger cycles of up <strong>to</strong> approximately 10 years, during which mean outflow and water‐levels are<br />

higher or lower than average. It is likely that these reflect natural cycles in rainfall and hence flow in the rivers<br />

discharging in<strong>to</strong> the lake. Rigorous statistical analyses are required <strong>to</strong> c<strong>on</strong>firm that the flow and water‐level<br />

regimes in recent years are significantly different from those that occurred in the past.<br />

Figure 3: <strong>Poyang</strong> <strong>Lake</strong> water levels (masl) measured close <strong>to</strong> the c<strong>on</strong>fluence with the Yangtze, 1956‐2009<br />

Figure 4: Flow (m 3 s ‐1 ) from <strong>Poyang</strong> <strong>Lake</strong> in<strong>to</strong> the Yangtze, 1956‐2009<br />

If the current c<strong>on</strong>diti<strong>on</strong>s are part of a natural cycle the resp<strong>on</strong>ses for managing the water in the lake may be<br />

very different from those adopted in resp<strong>on</strong>se <strong>to</strong> climate change or other anthropogenic activities. A careful<br />

examinati<strong>on</strong> of the data is required <strong>to</strong> ensure the his<strong>to</strong>rical c<strong>on</strong>text is unders<strong>to</strong>od and assessed as a basis for<br />

making decisi<strong>on</strong>s about regulating the lake through a sluice or other engineering structures, or how any<br />

structure could be operated <strong>to</strong> maintain the ecological character of the lake.<br />

Further examinati<strong>on</strong> of the flow data for the Yangtze River and the five rivers that flow in<strong>to</strong> the lake can also<br />

assist in determining how changes in the flow al<strong>on</strong>g these rivers have affected the lake. The discussi<strong>on</strong>s<br />

indicated that changes in the flow interacti<strong>on</strong>s between the Yangtze and the lake had occurred and also that at<br />

least some of the inflowing rivers were now heavily regulated. The complex interacti<strong>on</strong> with flows from the<br />

16


Yangtze and other rivers could be clearly shown through development of a hydraulic model. We were unsure of<br />

the extent of water regulati<strong>on</strong> al<strong>on</strong>g the five rivers that flow in<strong>to</strong> the <strong>Lake</strong>, or of plans <strong>to</strong> further regulate these<br />

rivers. Clarificati<strong>on</strong> of the current flow regimes and scenarios for the future would provide important<br />

informati<strong>on</strong> for decisi<strong>on</strong>‐makers c<strong>on</strong>sidering the manner in which the lake may be managed in the future. We<br />

have not seen these data and do not have a clear understanding of either the his<strong>to</strong>rical or future c<strong>on</strong>text for<br />

water management and hence whether the opti<strong>on</strong> being proposed is the best. Alternative water regulati<strong>on</strong><br />

opti<strong>on</strong>s that also support the natural flow regime of the lake may be available, for example by c<strong>on</strong>trolled<br />

releases of water from upstream dams combined with upgrading irrigati<strong>on</strong> facilities and other water<br />

c<strong>on</strong>servati<strong>on</strong> measures.<br />

The case made by the officials for Jiangxi Province emphasized that the planned water c<strong>on</strong>trol project would be<br />

designed <strong>to</strong> maintain the ecological character of the lake. While this objective is desirable and the case was<br />

clearly presented, we were not able <strong>to</strong> assess the data and discuss these in detail. In particular, we could not<br />

ascertain if any regula<strong>to</strong>ry structures would enable the natural flow regime of the lake <strong>to</strong> be maintained, or if<br />

there were alternative regula<strong>to</strong>ry approaches.<br />

5.2 Potential impacts <strong>on</strong> the submerged vegetati<strong>on</strong> in the <strong>Lake</strong><br />

As the lake is subject <strong>to</strong> a large input of nutrients from the catchment, the effect of increasing nutrient inflows<br />

<strong>on</strong> the vegetati<strong>on</strong> should be examined. The potential for the lake <strong>to</strong> switch from an ecological state<br />

characterised by clear water and submerged macrophyte species (e.g., Vallisneria spp.) <strong>to</strong> <strong>on</strong>e characterised by<br />

turbid water and high c<strong>on</strong>centrati<strong>on</strong>s of phy<strong>to</strong>plankt<strong>on</strong> should be explored further. It would be useful <strong>to</strong><br />

develop a c<strong>on</strong>ceptual model of the lake <strong>to</strong> illustrate the complexity of the inter‐relati<strong>on</strong>ships am<strong>on</strong>g key<br />

comp<strong>on</strong>ents of the biota and the chemical and physical envir<strong>on</strong>ment. In order for <strong>Poyang</strong> <strong>Lake</strong> <strong>to</strong> maintain its<br />

ecological character, it is imperative that the annual and inter‐annual variati<strong>on</strong>s in water level are maintained<br />

and as far as practical replicate normal c<strong>on</strong>diti<strong>on</strong>s. It is unclear whether the proposed operati<strong>on</strong> regime for the<br />

dam would res<strong>to</strong>re the ecological character of the lake or would instead lead <strong>to</strong> significant change through high<br />

water levels during the colder half of the year.<br />

As the ecology of the lake is largely dependent <strong>on</strong> the flow patterns the management of any regula<strong>to</strong>ry<br />

structures, such as a dam and sluice gates across the outlet, should be based <strong>on</strong> clear scientific evidence about<br />

the flow‐resp<strong>on</strong>ses of major comp<strong>on</strong>ents of the biota. In particular, the resp<strong>on</strong>ses of the vegetati<strong>on</strong> in the lake<br />

<strong>to</strong> changes in the flow should be examined. These interacti<strong>on</strong>s could be examined in situ and supported by<br />

empirical modeling of the germinati<strong>on</strong> and growth characteristics of the main species as developed by van der<br />

Valk and others at the Iowa State University in the USA. It is anticipated that – in order <strong>to</strong> maintain the current<br />

vegetati<strong>on</strong> communities in the lake ‐ the natural flow regime should be replicated through operati<strong>on</strong> of water<br />

regulati<strong>on</strong> structures with c<strong>on</strong>siderati<strong>on</strong> of the upper and lower depth <strong>to</strong>lerances of these species and the<br />

seas<strong>on</strong>ality and fluctuati<strong>on</strong>s in water depth that would have naturally occurred.<br />

The effect of increasing nutrient inflows <strong>on</strong> the vegetati<strong>on</strong> should be examined. This assessment could be d<strong>on</strong>e<br />

through in situ investigati<strong>on</strong> and correlati<strong>on</strong> of the occurrence of particular species in different lakes with<br />

different nutrient levels, or through mesocosm experiments under c<strong>on</strong>trolled c<strong>on</strong>diti<strong>on</strong>s, and through<br />

reference <strong>to</strong> the literature. An experimental approach using mesocosms (an enclosed and essentially selfsufficient,<br />

but not necessarily isolated experimental envir<strong>on</strong>ment that is <strong>on</strong> a larger scale than a labora<strong>to</strong>ry<br />

microcosm) could provide informati<strong>on</strong> specific <strong>to</strong> the c<strong>on</strong>diti<strong>on</strong>s in the lake (Moss 2007) and provide guidance<br />

for the operati<strong>on</strong> of any water regula<strong>to</strong>ry structures. Such guidance is currently not available and would be<br />

difficult <strong>to</strong> compile without further evidence and the development of an appropriate c<strong>on</strong>ceptual model that<br />

could be used <strong>to</strong> explore the interacti<strong>on</strong>s between the plants, nutrients and water fluctuati<strong>on</strong>s.<br />

There appears <strong>to</strong> be growing risk that the lake might switch from an ecological state characterised by clear<br />

water and submerged macrophyte species (for Vallisneria spp.) <strong>to</strong> <strong>on</strong>e characterised by turbid water and high<br />

c<strong>on</strong>centrati<strong>on</strong>s of phy<strong>to</strong>plankt<strong>on</strong>. Changes in ecological state of lakes and wetlands as a result of increased<br />

17


nutrient loads are well known and widely documented (Scheffer et al. 2001; Sim et al. 2006). There is initial<br />

evidence that this may be occurring in at least some of the lakes al<strong>on</strong>g the Yangtze River. Increased p<strong>on</strong>ding<br />

and retenti<strong>on</strong> of water in <strong>Poyang</strong> <strong>Lake</strong> by the proposed dam may increase the potential for such changes,<br />

especially if the nutrient load within the lake is not reduced. The change in ecological state being described<br />

here is often c<strong>on</strong>sidered as undesirable and near‐irreversible. That is, <strong>on</strong>ce the change has occurred it may not<br />

be possible <strong>to</strong> reverse it through treating the cause/s. While the primary cause is an increase in nutrients, the<br />

change may not be reversed by reducing the inflow of nutrients ‐ there may be sufficient nutrients already<br />

retained in the lake <strong>to</strong> maintain the changed c<strong>on</strong>diti<strong>on</strong>s for a c<strong>on</strong>siderable time period. Reducing the nutrient<br />

inflow may not have an immediate effect, but c<strong>on</strong>tinued inflow will exacerbate and deepen the problem <strong>to</strong> an<br />

extent that it could become intractable.<br />

The c<strong>on</strong>sequences of a change in ecological state of this type for the waterbirds, fish and mammals that use the<br />

lake could be extremely bad. For example, a switch from submerged macrophytes such as Vallisneria that<br />

produce tubers <strong>to</strong> a phy<strong>to</strong>plankt<strong>on</strong> dominated system will most likely result in the loss of the major food<br />

source for many waterbirds. The development of floating leaved macrophytes, such as Trapa, is possible under<br />

these c<strong>on</strong>diti<strong>on</strong>s, but will not replace the specific food sources that will be lost. Changes in the ecological state<br />

of lakes is a complex problem and is better avoided rather than treated <strong>on</strong>ce it has occurred – the latter may<br />

simply not be possible. A c<strong>on</strong>ceptual model of the nutrient‐plant interacti<strong>on</strong>s could be used <strong>to</strong> determine if<br />

such a change is likely for <strong>Poyang</strong> <strong>Lake</strong>. The abovementi<strong>on</strong>ed experimental approach using mesocosms could<br />

also provide valuable informati<strong>on</strong>.<br />

A key c<strong>on</strong>cern when c<strong>on</strong>sidering the ecology of the lake and likely resp<strong>on</strong>ses <strong>to</strong> a management regime imposed<br />

through a dam is the poor understanding of the inter‐relati<strong>on</strong>ships between the nutrient inflows and the biota<br />

of the lake and how these are affected by the hydrology. This is a complex, multi‐disciplinary issue and<br />

warrants further investigati<strong>on</strong>. As a starting point, it could be very useful <strong>to</strong> develop a c<strong>on</strong>ceptual model of the<br />

lake <strong>to</strong> illustrate the complexity of the inter‐relati<strong>on</strong>ships am<strong>on</strong>g key comp<strong>on</strong>ents of the biota and the chemical<br />

and physical envir<strong>on</strong>ment; such models have been used for a l<strong>on</strong>g time in limnological analyses of lakes with<br />

more recent pic<strong>to</strong>rial models now also being available, such as those developed by the Queensland Wetland<br />

Program (http://www.epa.qld.gov.au/UAT/wetlandinfo/<strong>site</strong>/ScienceAndResearch/C<strong>on</strong>ceptualModels.html).<br />

The initial c<strong>on</strong>ceptual models could then be used <strong>to</strong> more explicitly examine particular processes and<br />

interacti<strong>on</strong>s <strong>to</strong> ensure that the c<strong>on</strong>sequences of the changes in the hydrology of the lake are unders<strong>to</strong>od and<br />

the informati<strong>on</strong> made available <strong>to</strong> those resp<strong>on</strong>sible for managing the lake. Many examples of c<strong>on</strong>ceptual<br />

models for wetlands/lakes exist and could provide a working basis for developing a suitable model for <strong>Poyang</strong><br />

<strong>Lake</strong> (as outlined in text books by Keddy 2000; Richards<strong>on</strong> 2008; Mitsch et al. 2009).<br />

5.3 Potential impacts Up<strong>on</strong> Migra<strong>to</strong>ry Waterbirds Wintering at <strong>Poyang</strong> <strong>Lake</strong><br />

<strong>Poyang</strong> <strong>Lake</strong> and the other wetlands in the Yangtze River floodplain have extraordinary importance for cranes,<br />

waterfowl, and other waterbird species. Recent counts indicate that about 1.1 milli<strong>on</strong> individuals of 24 species<br />

of Anatidae winter in <strong>China</strong>, with about 80% in the Yangtze floodplain (Cao et al. 2008a). <strong>Poyang</strong> <strong>Lake</strong> is by far<br />

the most important of these wetlands for waterbirds. Over five years (1997‐2001), <strong>Poyang</strong> <strong>Lake</strong> had the largest<br />

winter count in East Asia, according <strong>to</strong> the Asian Waterbird Census – its 1997 count of 353,737 birds was 73%<br />

higher than any other locati<strong>on</strong> during this five‐year period (Li et al. 2004).<br />

Yet waterbird numbers in <strong>China</strong> have declined dramatically (see Cao et al. 2008a and 2008b), possibly<br />

indicating threats <strong>on</strong> both winter and breeding grounds. Lu (1996) estimated Anatidae numbers in <strong>China</strong> in the<br />

early 1990s at 3‐4 milli<strong>on</strong>, as compared <strong>to</strong> a current estimate of 1.1 milli<strong>on</strong> (Cao et al. 2008a). Goose<br />

populati<strong>on</strong>s in particular have declined. All five goose species (lesser white‐fr<strong>on</strong>ted goose Anser eryphropus,<br />

greater white‐fr<strong>on</strong>ted goose A. albifr<strong>on</strong>s, bean goose A. fabalis, greylag goose A. anser, swan goose A.<br />

cygnoides) wintering regularly at <strong>Poyang</strong> <strong>Lake</strong> reflect these trends (Wetlands Internati<strong>on</strong>al 2006). Since the mid<br />

1980s, breeding populati<strong>on</strong>s of greater white‐fr<strong>on</strong>ted geese and bean geese– that migrate from the Arctic <strong>to</strong><br />

<strong>China</strong> ‐‐ have declined by 80% and 65% respectively (Syroechkivskiy 2006). Swan geese, breeding in northeast<br />

18


<strong>China</strong>, southeast Russia and eastern M<strong>on</strong>golia, have suffered repeated years of poor reproducti<strong>on</strong> across large<br />

parts of the breeding range in recent years due <strong>to</strong> drought and human disturbance (O. Goroshko, N.<br />

Tseveenmyadag, and L. Su, pers<strong>on</strong>al communicati<strong>on</strong>s). Over half the world populati<strong>on</strong> of the threatened swan<br />

goose winters at <strong>Poyang</strong> <strong>Lake</strong>.<br />

Accurate counts are very difficult at <strong>Poyang</strong>, so that it is more prudent <strong>to</strong> rely up<strong>on</strong> counts over multiple years.<br />

But numbers at <strong>Poyang</strong> seem <strong>to</strong> be holding steady or even increasing compared with earlier years, in c<strong>on</strong>trast<br />

<strong>to</strong> other wetlands in the regi<strong>on</strong> (Cao et al. 2009, Cao Lei unpublished data, Ji et al. 2007).<br />

<strong>Poyang</strong> is also remarkable for its importance <strong>to</strong> numerous groups of birds with highly diverse feeding habits<br />

(Barzen 2008). The geese (other than the swan geese) bel<strong>on</strong>g <strong>to</strong> the grazing foraging guild that feeds primarily<br />

<strong>on</strong> grasses and sedges that occur <strong>on</strong> upper edges of the wetland; these plants grow during the cold seas<strong>on</strong><br />

period when they are exposed <strong>to</strong> the air (see Barzen 2008). Siberian Grus leucogeranus, white‐naped G. vipio,<br />

and hooded cranes G. m<strong>on</strong>acha, tundra swans Cygnus columbianus and swan geese form the tuber‐feeding<br />

foraging guild ‐‐ all feed <strong>on</strong> tubers of submerged aquatic plants, primarily Vallisneria. Water levels in both<br />

summer and winter are critical for these bird species. Summer water levels must be suited <strong>to</strong> growth of the<br />

plants (unlike the sedges and grasses, they are deep water specialists that grow during the warm seas<strong>on</strong>s);<br />

during winter, Vallisneria is senescent, but the birds require shallow water or wet mud so that they can access<br />

the tubers. Deep water or dry mud prevents cranes and other birds from utilizing this food. Siberian cranes<br />

primarily feed at water depths < 30 cm, and occasi<strong>on</strong>ally up <strong>to</strong> 50 cm (Barzen 2008). If water levels were<br />

maintained at 14 or 16 meters above sea level ( Wu S<strong>on</strong>g elevati<strong>on</strong>) for even porti<strong>on</strong>s of the wintering period,<br />

almost all current habitat would be deeply submerged and tubers unavailable <strong>to</strong> the cranes. The few areas<br />

remaining would force the birds <strong>to</strong> forage near the upper edges of the wetland, where human disturbance is<br />

high (Barzen et al. 2009). Cranes, however, will not feed or roost near people at <strong>Poyang</strong>.<br />

Other birds form the fish‐eating foraging guild, including the oriental s<strong>to</strong>rk. Over 95% of this endangered<br />

species winters at <strong>Poyang</strong>. The oriental s<strong>to</strong>rk specializes in fish injured or trapped in shallows after water levels<br />

drop. Significant changes in winter water levels could remove this favored habitat and dramatically affect this<br />

species.<br />

Collectively these species depend <strong>on</strong> <strong>Poyang</strong> <strong>Lake</strong> in winter for survival. The c<strong>on</strong>diti<strong>on</strong> of alternate habitats<br />

within the lower Yangtze River floodplain is declining (Fang et al. 2006). D<strong>on</strong>gting <strong>Lake</strong>, for example, has in<br />

recent years lost almost all its tuber feeding birds, while over the last five years, tuber‐feeding birds have<br />

drastically declined at Shengjin <strong>Lake</strong> (Fox et al. in press). Loss of <strong>Poyang</strong> <strong>Lake</strong> as foraging habitat due <strong>to</strong> high<br />

winter water levels would likely have catastrophic impact <strong>on</strong> a suite of threatened or declining species.<br />

If available habitats at <strong>Poyang</strong> <strong>Lake</strong> were reduced through dam c<strong>on</strong>structi<strong>on</strong> or other development projects,<br />

would birds bel<strong>on</strong>ging <strong>to</strong> different foraging guilds find alternate habitats elsewhere? The Siberian crane is the<br />

best known of these species. The most recent waterbird surveys of the lower Yangtze River floodplain have<br />

found less than 0.5% of the world’s Siberian cranes utilizing wetlands outside of <strong>Poyang</strong> <strong>Lake</strong> (Barter et al.<br />

2005, Cao Lei unpublished data). Tundra swans, another tuber feeder, occur in other areas of the lower<br />

Yangtze River so tubers are likely available elsewhere. Most of these wetland areas, however, have water<br />

depths that are <strong>to</strong>o deep for Siberian cranes <strong>to</strong> forage efficiently. Further, since winter areas of Siberian cranes<br />

were described in 1981, few records have ever occurred outside of <strong>Poyang</strong> <strong>Lake</strong> (Cheng 1987). It is unlikely<br />

that the Siberian cranes could persist if <strong>Poyang</strong> <strong>Lake</strong> were no l<strong>on</strong>ger available – a high risk of extincti<strong>on</strong> for<br />

Siberian cranes would result from loss of <strong>Poyang</strong> <strong>Lake</strong> as a wintering habitat for this species.<br />

5.4 Potential impacts <strong>on</strong> finless porpoises and fisheries<br />

The finless porpoise (Neophocaena phocaenoides asiaeorientalis) is the <strong>on</strong>ly freshwater porpoise that lives in<br />

the Yantzse River main channel, and D<strong>on</strong>gting and <strong>Poyang</strong> <strong>Lake</strong>s are the two <strong>on</strong>ly naturally c<strong>on</strong>nected lakes<br />

with Yangtze River. In the past four years, the number of finless porpoise has declined rapidly, from 1800 in<br />

2006 <strong>to</strong> 1200 in 2010 (An<strong>on</strong>ymous 2010). The populati<strong>on</strong> within <strong>Poyang</strong> <strong>Lake</strong> is estimated <strong>to</strong> be around 400<br />

19


individuals (Zhao 2008). This alarming decline has mainly been due <strong>to</strong> increased threats from navigati<strong>on</strong>, over<br />

fishing, water polluti<strong>on</strong> and hydro‐engineering projects.<br />

Finless porpoises migrate from the lakes <strong>to</strong> the Yangtze River and from Yangtze <strong>to</strong> the lakes according <strong>to</strong> the<br />

food and water situati<strong>on</strong>. Fish migrati<strong>on</strong> has a close relati<strong>on</strong> with number of porpoises. The porpoise will follow<br />

fish groups that move from Yangtze <strong>to</strong> the lake during the spawning seas<strong>on</strong> in spring and vice versa (Wei et al.<br />

2002) The other important reas<strong>on</strong> for porpoise migrati<strong>on</strong> is the genetic movement for porpoise healthy group<br />

according <strong>to</strong> the recent research results from Chinese Academy of Sciences (Xia et al. 2004). Any hydraulic<br />

project that cut off the migrate routes would highly affect the safety of this species both in its food and living<br />

envir<strong>on</strong>ment, and finally could cause a genetically isolated group of <strong>Poyang</strong> porpoises and decrease the <strong>to</strong>tal<br />

number due <strong>to</strong> group weakness.<br />

In another way, the hydraulic project is subject <strong>to</strong> changing the natural hydrologic situati<strong>on</strong>, decrease the flow<br />

and capacities of self‐purificati<strong>on</strong>, and drastically change the envir<strong>on</strong>ment of the aqua‐biological system which<br />

in turn, will degrade the habitat of the porpoise.<br />

5.5 Potential impacts <strong>on</strong> <strong>Poyang</strong> <strong>Lake</strong> Nature Reserve and other nature reserves in<br />

<strong>Poyang</strong> <strong>Lake</strong><br />

The Jiangxi Government deserves str<strong>on</strong>g praise for its efforts for wetland projecti<strong>on</strong> over the past 25 years. In<br />

particular, a network of nature reserves has been established across the <strong>Poyang</strong> <strong>Lake</strong> basin, including two<br />

nati<strong>on</strong>al reserves, two provincial level reserves, and 15 reserves at the county level. The migra<strong>to</strong>ry waterbirds<br />

depend <strong>on</strong> highly variable habitat c<strong>on</strong>diti<strong>on</strong>s, primarily due <strong>to</strong> fluctuati<strong>on</strong>s in water and food availability, and<br />

accordingly depend <strong>on</strong> access <strong>to</strong> diverse habitats spread across the lake.<br />

If after discussi<strong>on</strong> using the best available scientific data, it is decided that the proposed dam should be built,<br />

the dam will need <strong>to</strong> be managed in a way that can res<strong>to</strong>re the complex and incredibly important hydrological<br />

c<strong>on</strong>diti<strong>on</strong>s that have characterized the lake over the last five decades. In this case, it may be possible that<br />

migra<strong>to</strong>ry waterbirds will c<strong>on</strong>tinue <strong>to</strong> find suitable roosting and feeding c<strong>on</strong>diti<strong>on</strong>s within PLNR and the other<br />

nature reserves. While the water c<strong>on</strong>trol structure might benefit birds by preventing extremely low water<br />

levels in winter, the fluctuati<strong>on</strong>s within and between years are vital <strong>to</strong> the ecology of waterbirds and their<br />

foods. Low winter water levels in the part of the lake near PLNR should fluctuate around the his<strong>to</strong>ric average<br />

lows of 12.0 meters above sea level (Wu S<strong>on</strong>g elevati<strong>on</strong>) as recorded at Wucheng. In winter, there are<br />

significant differences in water levels within the lake basin ‐ water levels exhibit a slope, with higher water<br />

levels in the south and lower levels in the north near the Yangtze. Therefore the corresp<strong>on</strong>ding water levels at<br />

Xingzi should fluctuate around the his<strong>to</strong>ric winter low water levels of 9.0 meters Wu S<strong>on</strong>g. Due <strong>to</strong> the flat<br />

<strong>to</strong>pography and interc<strong>on</strong>nected hydrology of the entire lake basin, significant changes <strong>to</strong> the lake system (for<br />

example, maintaining water at 14 or 16 meters Wu S<strong>on</strong>g near Wucheng) would change the ecological character<br />

of all or almost all of the nature reserves in the lake. In particular, significantly higher water levels in late<br />

autumn, winter, or early spring (as compared <strong>to</strong> the past decades of records) would submerge all current<br />

shallows and mudflats significant <strong>to</strong> waterbirds. At 14 meters or 16 meters Wu S<strong>on</strong>g, vegetati<strong>on</strong> might shift<br />

upward in the basin but would occur over much smaller areas and in close proximity <strong>to</strong> upland areas with levels<br />

of human activity that might be impossible for waterbirds <strong>to</strong> <strong>to</strong>lerate (Barzen et al. 2009). Note, however, that<br />

winter water levels of 12 meters at Xingzi would be accompanied by water levels perhaps 2 meters or more<br />

higher than normal in mid winter at PLNR, with the significant negative impacts just described.<br />

Under such c<strong>on</strong>diti<strong>on</strong>s, there might be opportunity <strong>to</strong> shift the boundaries of PLNR and other reserves in<br />

resp<strong>on</strong>se <strong>to</strong> changes in vegetati<strong>on</strong> distributi<strong>on</strong> and bird feeding areas , but such upshore shifts in the reserve<br />

boundaries will be limited because of the proximity of human habitati<strong>on</strong> and activities. Overall the extent of<br />

foraging habitat available <strong>to</strong> most foraging guilds would be severely reduced due <strong>to</strong> increased water levels.<br />

It may be possible separately <strong>to</strong> manage water <strong>to</strong> provide waterbird habitat in areas that lose their c<strong>on</strong>necti<strong>on</strong><br />

in winter <strong>to</strong> the rivers or main body of the lake – such as some of the nine lakes within PLNR or certain<br />

20


peripheral areas including reservoirs such as Shi Xia Hu that has in the past provided significant waterbird<br />

habitat. Yet data over the past 11 years for Dahu Chi and Sha Hu, two of the most important of the nine lakes<br />

in PLNR, indicate that these relatively small wetlands do not support significant numbers of all foraging guilds<br />

at <strong>on</strong>ce and very seldom (if ever) have most or all of the winter populati<strong>on</strong>s present for any of the threatened<br />

species such as Siberian cranes or oriental s<strong>to</strong>rks. For the vast majority of the time, these birds are dispersed<br />

across multiple locati<strong>on</strong>s. It is highly unlikely that relatively small areas could be artificially managed <strong>to</strong> sustain<br />

400,000 waterbirds for 5‐6 m<strong>on</strong>ths every winter in<strong>to</strong> the indefinite future. Even if most years provided food<br />

for the cranes, for example, failure of Vallisneria in just <strong>on</strong>e or two years out of ten could cause widespread<br />

mortality.<br />

In additi<strong>on</strong>, if high water levels are maintained in <strong>Poyang</strong> <strong>Lake</strong>, it becomes difficult <strong>to</strong> lower water levels within<br />

impoundments that are intensively managed for winter waterfowl habitat by gravity outflow. Between 14 and<br />

15 m Wu S<strong>on</strong>g it would become increasingly necessary <strong>to</strong> actively pump water out of the impoundments for<br />

proper winter water management <strong>to</strong> occur. Above 16 m Wu S<strong>on</strong>g it would not be possible <strong>to</strong> maintain<br />

separate basins without c<strong>on</strong>structing additi<strong>on</strong>al levees <strong>to</strong> isolate the lakes. Isolati<strong>on</strong> of the lakes by<br />

c<strong>on</strong>structing levees, however, may cause water clarity in summer <strong>to</strong> decline, that would decrease Vallisneria<br />

productivity and winter waterfowl habitat quality.<br />

Given future uncertainties due <strong>to</strong> changes in the watershed and in climate, active management of these lakes<br />

should be undertaken <strong>on</strong> an experimental basis <strong>to</strong> ensure the ecological character is maintained, with careful<br />

m<strong>on</strong>i<strong>to</strong>ring so that we can learn more about how <strong>to</strong> sustain habitats for waterbirds and, where necessary,<br />

adjust the management <strong>to</strong> ensure this occurs. The importance of doing this at a whole‐of‐lake scale and within<br />

a watershed c<strong>on</strong>text is again emphasized.<br />

5.6 Design and management of a dam<br />

It is premature for detailed planning and so currently there is very little informati<strong>on</strong> <strong>on</strong> the likely design of the<br />

hydraulic structure (i.e., the dam) that might be c<strong>on</strong>structed at the outlet of <strong>Poyang</strong> <strong>Lake</strong>. However, “current<br />

thinking” is that the dam will be c<strong>on</strong>structed between low hills (Pingfeng and Changling) at the narrowest point<br />

of the channel that c<strong>on</strong>nects the lake <strong>to</strong> the Yangtze River, close <strong>to</strong> the <strong>to</strong>wn of Xingzi. This point,<br />

approximately 27 km upstream of the c<strong>on</strong>fluence with the Yangtze, is 2,800 m wide and the <strong>to</strong>tal dam width<br />

(including buttressing <strong>on</strong> either side) would be 2,986 m. The dam would comprise a large number of sluice<br />

gates (16‐20 m wide). These gates would vary in height, from 1‐5 m, depending <strong>on</strong> their exact positi<strong>on</strong> across<br />

the channel. They could be lowered and raised in different combinati<strong>on</strong>s <strong>to</strong> enable complete c<strong>on</strong>trol of the<br />

outflow from <strong>Poyang</strong> <strong>Lake</strong> (Figure 5). A ship lock would be built <strong>on</strong> the west side of the dam <strong>to</strong> enable the<br />

passage of ships between the lake and the Yangtze River. A fish pass would be c<strong>on</strong>structed <strong>on</strong> the east bank <strong>to</strong><br />

enable the movement of fish at times when all the sluice gates are closed.<br />

Figure 5: Artists impressi<strong>on</strong> of the possible dam <strong>to</strong> be c<strong>on</strong>structed at the outlet of <strong>Poyang</strong> <strong>Lake</strong>.<br />

21


Detailed plans for the operati<strong>on</strong> of the dam have not yet been developed. However, it is anticipated that the<br />

dam will be operated <strong>to</strong> fulfill a number of socio‐ec<strong>on</strong>omic objectives (i.e., ensuring the free movement of<br />

ships and providing water for irrigati<strong>on</strong> and supply <strong>to</strong> <strong>to</strong>wns and villages) as well as ecological objectives (i.e.,<br />

maintenance of the lake ecology and provisi<strong>on</strong> of habitat for waterbirds) and also fulfilling downstream needs<br />

in the Lower Yangtze. With these objectives in mind, it is envisaged that the dam operati<strong>on</strong> will be divided in<strong>to</strong><br />

a regime comprising four broad periods each year (Table 1).<br />

Table 1:<br />

M<strong>on</strong>ths<br />

April <strong>to</strong> August (wet seas<strong>on</strong>)<br />

Potential operating regime of the dam at the outlet from <strong>Poyang</strong> <strong>Lake</strong><br />

September (end of wet seas<strong>on</strong>)<br />

Oc<strong>to</strong>ber<br />

November – March<br />

Operating regime<br />

All sluice gates open. The lake fully c<strong>on</strong>nected <strong>to</strong> the Yangtze River<br />

All sluice gates closed <strong>to</strong> s<strong>to</strong>re the last of the inflowing flood and <strong>to</strong><br />

ensure water levels in the lake reach approximately 17.5 m<br />

Some sluice gates open and some closed. Water levels in the lake<br />

allowed <strong>to</strong> drop <strong>to</strong> approximately 16 m<br />

Some sluice gates open and some closed. Gates operated <strong>to</strong> draw water<br />

levels down in accordance with downstream needs as well as the habitat<br />

requirements of migra<strong>to</strong>ry birds but also <strong>to</strong> maintain lake water levels for<br />

shipping and water supply.<br />

Principal c<strong>on</strong>cerns associated with the potential dam are:<br />

The operati<strong>on</strong> will reduce the natural variability in lake water‐levels. Naturally both the seas<strong>on</strong>al and interannual<br />

variati<strong>on</strong> of water levels is high as the lake “s<strong>to</strong>res” <strong>on</strong>ly a relatively small proporti<strong>on</strong> of the <strong>to</strong>tal<br />

inflow. Even when full (i.e., water level 22.6 m) the <strong>to</strong>tal s<strong>to</strong>rage is 34 Bm 3 (i.e., 24% of the mean annual<br />

runoff of 143.6 Bm 3 ). Although the design of the dam is such that this variability could be replicated,<br />

because of the needs of shipping and water supply, it seems likely that a less variable pattern – the<br />

ecological c<strong>on</strong>sequences of which are difficult <strong>to</strong> predict ‐ will be imposed <strong>on</strong> the lake.<br />

Dry seas<strong>on</strong> water‐levels will be maintained at <strong>to</strong>o high a level. Again, in principle it will be possible <strong>to</strong> draw<br />

down the water levels <strong>to</strong> mimic the natural dry seas<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>. However, because this objective<br />

c<strong>on</strong>flicts with the needs of shipping and water supply, in practice it is probable that water levels will be<br />

maintained at higher than natural levels. This acti<strong>on</strong> could have a devastating impact <strong>on</strong> the natural<br />

ecology of the lake (including the waterbirds) which has adapted <strong>to</strong> the naturally low levels that occur.<br />

The lake’s c<strong>on</strong>necti<strong>on</strong> with the Yangtze will be disrupted. The sluice gates will enable a near full c<strong>on</strong>necti<strong>on</strong><br />

with the Yangtze and this is a far better design than a solid dam. Nevertheless, because of the buttresses<br />

needed <strong>to</strong> support each gate, the c<strong>on</strong>necti<strong>on</strong> with the Yangtze will not be natural. The ecological<br />

implicati<strong>on</strong>s of this are not clear. For instance, it is not known if the finless porpoise will navigate through<br />

open gates, even if they are 20 m across.<br />

5.7 Influences due <strong>to</strong> development within the lake basin<br />

Approximately 44 milli<strong>on</strong> people live in the <strong>Poyang</strong> <strong>Lake</strong> basin. Upstream development has modified flows <strong>on</strong><br />

all five of the major rivers that flow in<strong>to</strong> the lake. Water is abstracted for upstream irrigati<strong>on</strong> as well as for<br />

urban and rural water supply. The exact figures <strong>on</strong> the amount of water abstracted and the <strong>to</strong>tal irrigated area<br />

were unavailable for this study. Nevertheless, it is known that upstream abstracti<strong>on</strong>s are substantial. Within<br />

22


the basin a huge number of medium and small dams (> 3,000) and several large dams have been c<strong>on</strong>structed.<br />

For example, at least 15 large dams (s<strong>to</strong>ring a combined <strong>to</strong>tal of several billi<strong>on</strong> m 3 ) have been built <strong>on</strong> the Gan<br />

River and its tributaries. As well as facilitating abstracti<strong>on</strong>, thereby reducing the <strong>to</strong>tal flow, these may have<br />

altered the timing of inflows in<strong>to</strong> the lake.<br />

Although the details are not yet known, additi<strong>on</strong>al upstream development is anticipated from the <strong>Poyang</strong> <strong>Lake</strong><br />

Eco‐Ec<strong>on</strong>omic Development Z<strong>on</strong>e that is currently being planned. This development, in c<strong>on</strong>juncti<strong>on</strong> with<br />

populati<strong>on</strong> rise and possible climate change, is likely <strong>to</strong> further increase pressure <strong>on</strong> the basin’s water<br />

resources and, if not anticipated and mitigated, may well lead <strong>to</strong> additi<strong>on</strong>al ecological stress within the <strong>Lake</strong>. In<br />

this c<strong>on</strong>text it is suggested that the Basin should be managed as a single system. Whether or not the dam is<br />

built at the outlet of the <strong>Poyang</strong> <strong>Lake</strong>, all the hydraulic infrastructure within the basin should be operated in an<br />

integrated manner and effectively treated as a single system. Detailed evaluati<strong>on</strong> is needed <strong>to</strong> c<strong>on</strong>firm, but it is<br />

possible that some of the negative ecological phenomena that are believed <strong>to</strong> be currently occurring within the<br />

lake, and may occur in future, could be mitigated by modifying the operating regimes of the existing and<br />

planned upstream dams. For example, it might be possible <strong>to</strong> make larger releases from upstream dams in the<br />

dry seas<strong>on</strong> in order <strong>to</strong> prevent the lake level dropping <strong>to</strong> ecologically harmful levels. This measure and other<br />

possibilities should be investigated in detail before the opti<strong>on</strong> of building a new dam at the outlet from <strong>Poyang</strong><br />

<strong>Lake</strong> is finalized. Alternatives <strong>to</strong> the <strong>Poyang</strong> <strong>Lake</strong> dam need <strong>to</strong> be fully c<strong>on</strong>sidered and reas<strong>on</strong>s (<strong>to</strong>gether with<br />

supportive data) given <strong>to</strong> why they have been rejected prior <strong>to</strong> deciding <strong>to</strong> proceed with c<strong>on</strong>structi<strong>on</strong> of the<br />

<strong>Poyang</strong> <strong>Lake</strong> dam.<br />

5.8 Possible negative impacts from l<strong>on</strong>g­term climate variability and change<br />

With a l<strong>on</strong>g his<strong>to</strong>ry of the evoluti<strong>on</strong> of <strong>Poyang</strong> <strong>Lake</strong>, the dry and flood periods have altered during its life time.<br />

His<strong>to</strong>rical <strong>site</strong>s have been found in the lake basin from different times during the last 2000 years, many of them<br />

are ancient buildings of villages and <strong>to</strong>wns, and others are farmland located in the present water body in the<br />

center of the lake (Su 1992). These discoveries show that the lake has several times dried and flooded during<br />

the his<strong>to</strong>ry of human settlement in resp<strong>on</strong>se <strong>to</strong> medium‐term climate cycles. Recent research shows that the<br />

cycles can be 11, 22 or 30 years and will have str<strong>on</strong>g temporary impacts <strong>on</strong> the freshwater and wetland<br />

ecosystem (Zhu 2007). Recent extreme weather since 2004 has also c<strong>on</strong>tributed <strong>to</strong> the low water levels in<br />

<strong>Poyang</strong> <strong>Lake</strong>, with adverse c<strong>on</strong>sequences for both people and wildlife, especially in the droughts in 2007 and<br />

2008.<br />

As stated above, <strong>Poyang</strong> <strong>Lake</strong> is a flood plain lake with water fluctuati<strong>on</strong>s of 13 m within a year providing a<br />

wide range of natural wetlands with diversified land features and habitats for wintering birds and other key<br />

species. These features underpin the internati<strong>on</strong>al importance of the wetland, as recognized by its listing under<br />

the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong>. Ongoing climate variability and change, including further extreme events, raise a<br />

number of issues that warrant further attenti<strong>on</strong>:<br />

The ecological character of the lake has been established over a l<strong>on</strong>g‐time period in resp<strong>on</strong>se <strong>to</strong> variability<br />

in climate and the hydrology across the watershed. The current character of the lake is a combinati<strong>on</strong> of<br />

events and processes over l<strong>on</strong>g and shorter time scales, including the impact of recent human‐induced<br />

climate change. In managing the lake it is important that the influence of these changes and their interrelati<strong>on</strong>ships<br />

are well unders<strong>to</strong>od – failure <strong>to</strong> do so could result in ill‐informed and inappropriate<br />

management decisi<strong>on</strong>s being made. Lack of awareness of natural processes of the Central Yangtze<br />

wetland ecosystem and its biodiversity, based <strong>on</strong> a short time series of extreme weather data could result<br />

in the implementati<strong>on</strong> of major engineering‐related soluti<strong>on</strong>s with unexpected negative impacts <strong>on</strong> the<br />

water levels and ecology of the lake.<br />

Over the past millennium people and nature have <strong>to</strong>gether shaped the character and existing values of the<br />

lake with a central water body and adjacent smaller sub‐lakes ringed or partly ringed by ancient low dykes<br />

that could be used as <strong>to</strong> regulate water levels and water retenti<strong>on</strong>, forming habitats that support the<br />

23


Siberian crane and other wintering birds, and which in summer are merged by floodwater. Based <strong>on</strong><br />

investigati<strong>on</strong>s by different agencies and using different approaches the <strong>to</strong>tal number of wintering birds <strong>on</strong><br />

the lake varied from around 730,000 <strong>to</strong> 130,000 over the period 2004 <strong>to</strong> 2009. The variati<strong>on</strong> has been<br />

attributed <strong>to</strong> the influence of water levels as well as different survey methods and equipment and<br />

experience of the observers. An average of 30‐60 % of the wintering birds occurred in <strong>Poyang</strong> <strong>Lake</strong><br />

Nati<strong>on</strong>al Nature Reserve and Nanji Shan Nati<strong>on</strong>al Nature Reserve, with many other birds being distributed<br />

in other regi<strong>on</strong>s of <strong>Poyang</strong> <strong>Lake</strong>. These data should be further investigated using standardized methods <strong>to</strong><br />

further elaborate the importance of fluctuating water levels <strong>on</strong> the wintering populati<strong>on</strong>s.<br />

The effect of l<strong>on</strong>g‐term climate variability and climate change and interacti<strong>on</strong>s with other land and water<br />

management activities across the watershed ‐‐ for example, the impact of dams <strong>on</strong> the rivers flowing in<strong>to</strong><br />

<strong>Poyang</strong> ‐‐ needs further investigati<strong>on</strong> within the c<strong>on</strong>text of the project <strong>to</strong> dam the outflow of the lake. The<br />

current proposal has been made within the c<strong>on</strong>text of a recent drought and lower water levels and would<br />

benefit from further analysis of the l<strong>on</strong>g‐term changes <strong>to</strong> identify the importance of climate cycles <strong>on</strong> the<br />

water flows and s<strong>to</strong>rage of water in the lake during the drier period of the year. As a complex of fac<strong>to</strong>rs<br />

seems resp<strong>on</strong>sible for the recent low winter water levels, a more thorough investigati<strong>on</strong> of these fac<strong>to</strong>rs<br />

and the effectiveness of alternative soluti<strong>on</strong>s should be carried out over a period of years. The recent<br />

changes, occurring over a very short span of time, are very difficult <strong>to</strong> evaluate without the collecti<strong>on</strong> of<br />

more data over the next years.<br />

6. CONCLUSION AND RECOMMENDATIONS<br />

The <strong>Ramsar</strong> team of experts highly appreciated Jiangxi Province’s effort <strong>to</strong> seek external technical input, and<br />

the opportunity for our team <strong>to</strong> <strong>visit</strong> <strong>Poyang</strong> <strong>Lake</strong> and discuss the project with the relevant agencies. Given<br />

the importance of Jiangxi’s wetland c<strong>on</strong>servati<strong>on</strong> efforts, we would be pleased <strong>to</strong> assist further as needed.<br />

Jiangxi’s c<strong>on</strong>certed effort <strong>to</strong> improve water quality is an extremely important aspect of safeguarding <strong>Poyang</strong><br />

wetlands. We applaud Jiangxi’s commitment <strong>to</strong> these activities for both the lake basin and <strong>Poyang</strong>’s extensive<br />

watershed.<br />

The team wishes <strong>to</strong> stress that the recent problem with perceived ecological change in the wetlands at <strong>Poyang</strong><br />

<strong>Lake</strong> needs <strong>to</strong> be more thoroughly substantiated, based <strong>on</strong> quantitative data, with the causes for these<br />

changes investigated. This assessment should include rigorous statistical analyses <strong>to</strong> c<strong>on</strong>firm that in recent<br />

years water levels in <strong>Poyang</strong> <strong>Lake</strong> have, as is widely perceived, been declining more rapidly and lower than they<br />

have d<strong>on</strong>e his<strong>to</strong>rically. The relative importance of c<strong>on</strong>structi<strong>on</strong> of the Three Gorges Dam, of water regulati<strong>on</strong><br />

<strong>on</strong> the five rivers feeding in<strong>to</strong> <strong>Poyang</strong>, and of withdrawals of water for human use upstream and within the<br />

Basin of <strong>Poyang</strong> <strong>Lake</strong>, up<strong>on</strong> lake levels should be determined.<br />

Given the extraordinary importance of <strong>Poyang</strong> <strong>Lake</strong> for the local ecology and ec<strong>on</strong>omy, and for global<br />

biodiversity values, the team would also like <strong>to</strong> stress that full c<strong>on</strong>siderati<strong>on</strong> should be given <strong>to</strong> alternative<br />

measures for addressing these changes in order <strong>to</strong> maintain or res<strong>to</strong>re the ecological character of <strong>Poyang</strong> <strong>Lake</strong>.<br />

The relative costs and benefits of these alternatives can be compared with the proposed dam under different<br />

design scenarios and with <strong>on</strong>e another so that the most effective soluti<strong>on</strong>s can be selected. Possible<br />

alternatives include modifying the operating regimes <strong>on</strong> existing and planned dams upstream of the lake<br />

and/or the operating regime of the Three Gorges Dam. Reas<strong>on</strong>s as <strong>to</strong> why these (and other possibilities) have<br />

been rejected should be given prior <strong>to</strong> deciding <strong>to</strong> proceed with the dam at the lake outlet.<br />

One strategy that should be c<strong>on</strong>sidered as part of alternative soluti<strong>on</strong>s would be Payment for Ecosystem<br />

Services, where Jiangxi could receive significant development support <strong>to</strong> compensate for development<br />

opportunities foreg<strong>on</strong>e in order <strong>to</strong> sustain ecosystem benefits of regi<strong>on</strong>al or global significance.<br />

24


It is never possible <strong>to</strong> achieve all the possible socio‐ec<strong>on</strong>omic benefits that a dam might provide while<br />

simultaneously fully protecting the envir<strong>on</strong>ment. Nevertheless, in many circumstances the sustainability of a<br />

project will be enhanced if some socio‐ec<strong>on</strong>omic benefits are foreg<strong>on</strong>e in order <strong>to</strong> protect the envir<strong>on</strong>ment.<br />

Because the dam is now being c<strong>on</strong>sidered, we have the following str<strong>on</strong>g recommendati<strong>on</strong>s for safeguarding<br />

the ecology of the <strong>Poyang</strong> <strong>Lake</strong>, if the dam were <strong>to</strong> be built. By incorporating these c<strong>on</strong>siderati<strong>on</strong>s now in<strong>to</strong><br />

plans for the dam, its benefits and impacts can be better compared <strong>to</strong> other opti<strong>on</strong>s for <strong>Poyang</strong> <strong>Lake</strong><br />

Ensure that envir<strong>on</strong>mental c<strong>on</strong>cerns are dealt with throughout the planning process. Detailed plans for<br />

dam operati<strong>on</strong> need <strong>to</strong> be developed early in the design phase. This aspect should not be left, as is<br />

comm<strong>on</strong>ly d<strong>on</strong>e, until near the end of the project planning.<br />

Mimic the natural variability as closely as possible. Internati<strong>on</strong>al experience indicates that where wetlands<br />

need <strong>to</strong> be managed artificially, the best outcomes occur when management attempts <strong>to</strong> maintain or<br />

res<strong>to</strong>re natural variability and the characteristic ecology of the <strong>site</strong>, based <strong>on</strong> data from past years. Even<br />

though there will be implicati<strong>on</strong>s for shipping, irrigati<strong>on</strong> and rural and urban water supply, this variability<br />

should include drawing down the lake <strong>to</strong> near natural levels every year. Computer models could be<br />

developed <strong>to</strong> predict the pattern of natural water levels given specific rainfall and hence flow c<strong>on</strong>diti<strong>on</strong>s in<br />

the <strong>Lake</strong> basin. These simulati<strong>on</strong>s could be used <strong>to</strong> guide the exact pattern of opening and closing of sluice<br />

gates in order <strong>to</strong> simulate the natural levels as closely as possible.<br />

Never close all the sluice gates. It is anticipated that all the sluice gates will be closed for a number of<br />

weeks in September. However, though it would take l<strong>on</strong>ger, it would be possible <strong>to</strong> fill the lake even with<br />

some gates left open. This adjustment would maintain a better c<strong>on</strong>necti<strong>on</strong> with the Yangtze throughout<br />

the year. It might also do away with the need for a fish ladder – fish ladders can be very costly and are<br />

often ineffective for many fish species.<br />

6.1 Informati<strong>on</strong> gaps:<br />

A large amount of informati<strong>on</strong> was provided <strong>on</strong> the ecological character of <strong>Poyang</strong> <strong>Lake</strong> covering the<br />

biology, water chemistry and hydrology in particular. The informati<strong>on</strong> was largely provided during<br />

presentati<strong>on</strong>s and discussi<strong>on</strong>s with scientists and officials, but was not seen by the <strong>Ramsar</strong> team. The six<br />

reports being prepared by scientific research teams should be made publicly available as so<strong>on</strong> as possible<br />

and preferably c<strong>on</strong>sidered in an open scientific forum <strong>to</strong> support efforts <strong>to</strong> integrate the informati<strong>on</strong>.<br />

Much of the case in support of c<strong>on</strong>structing a water regulati<strong>on</strong> system (with a dam and sluice gates<br />

seemingly the favoured opti<strong>on</strong>) across the outlet of the lake <strong>to</strong> the Yangtze River is based <strong>on</strong> the recent<br />

extreme drying of the lake during the dry seas<strong>on</strong>. Further attenti<strong>on</strong> should be directed <strong>to</strong>wards examining<br />

the rainfall and water level/flow data and focus <strong>on</strong> the his<strong>to</strong>rical rainfall and water level patterns and<br />

provide a c<strong>on</strong>text for the current low levels of water in the dry seas<strong>on</strong>. This comparis<strong>on</strong> would help<br />

ascertain the extent <strong>to</strong> which the current c<strong>on</strong>diti<strong>on</strong>s are part of a natural short or l<strong>on</strong>g‐term cycle of<br />

rainfall change, the result of human activities within the watershed, or due <strong>to</strong> anthropogenic climate<br />

change.<br />

Further examinati<strong>on</strong> of the flow data for the Yangtze River and the five rivers that flow in<strong>to</strong> the <strong>Lake</strong> can<br />

also assist in determining how changes in the flow al<strong>on</strong>g these rivers have affected the lake. The<br />

discussi<strong>on</strong>s indicated that changes in the flow interacti<strong>on</strong>s between the Yangtze and the lake had occurred<br />

and also that at least some of the inflowing rivers were also now heavily regulated. The complex<br />

interacti<strong>on</strong> with flows from the Yangtze and other rivers could be clearly shown through development of a<br />

hydrological and an inter‐c<strong>on</strong>nected ecological resp<strong>on</strong>se model.<br />

25


6.2 Potential impacts <strong>on</strong> the submerged vegetati<strong>on</strong> in the <strong>Lake</strong><br />

As the lake is subject <strong>to</strong> a large input of nutrients from the catchment, the effect of increasing nutrient<br />

inflows <strong>on</strong> the vegetati<strong>on</strong> should be examined. The potential for the lake <strong>to</strong> switch from an ecological<br />

state characterised by clear water and submerged macrophyte species (e.g., Vallisneria spp.) <strong>to</strong> <strong>on</strong>e<br />

characterised by turbid water and high c<strong>on</strong>centrati<strong>on</strong>s of phy<strong>to</strong>plankt<strong>on</strong> should be explored.<br />

As the ecology of the lake is largely dependent <strong>on</strong> the flow patterns, the management of any regula<strong>to</strong>ry<br />

structures, such as a dam and sluice gates across the outlet, should be based <strong>on</strong> clear scientific evidence<br />

about the flow‐resp<strong>on</strong>ses of major comp<strong>on</strong>ents of the biota. In particular, the resp<strong>on</strong>ses of the vegetati<strong>on</strong><br />

in the lake <strong>to</strong> changes in the flow should be examined. These interacti<strong>on</strong>s could be examined in situ and<br />

supported by empirical modeling of the germinati<strong>on</strong> and growth characteristics of the main plant species.<br />

The effect of increasing nutrient inflows <strong>on</strong> the vegetati<strong>on</strong> should be examined. This could be d<strong>on</strong>e<br />

through in situ investigati<strong>on</strong> and correlati<strong>on</strong> of the occurrence of particular species in different lakes with<br />

different nutrient levels, or through mesocosm experiments under c<strong>on</strong>trolled c<strong>on</strong>diti<strong>on</strong>s, and through<br />

reference <strong>to</strong> the literature. An experimental approach using mesocosms could provide informati<strong>on</strong> specific<br />

<strong>to</strong> the c<strong>on</strong>diti<strong>on</strong>s in the lake and provide guidance for the operati<strong>on</strong> of any water regula<strong>to</strong>ry structures.<br />

A key c<strong>on</strong>cern when c<strong>on</strong>sidering the ecology of the lake and likely resp<strong>on</strong>ses <strong>to</strong> a management regime<br />

imposed through a dam is the poor understanding of the inter‐relati<strong>on</strong>ships between the nutrient inflows<br />

and the biota of the lake and how these are affected by the hydrology. This is a complex, multi‐disciplinary<br />

issue and warrants further investigati<strong>on</strong>. As a starting point, it could be very useful <strong>to</strong> develop a<br />

c<strong>on</strong>ceptual model of the lake <strong>to</strong> illustrate the complexity of the inter‐relati<strong>on</strong>ships am<strong>on</strong>g key comp<strong>on</strong>ents<br />

of the biota and the chemical and physical envir<strong>on</strong>ment.<br />

6.3 Potential impacts <strong>on</strong> migra<strong>to</strong>ry waterbirds and other animals<br />

Given the severe stresses <strong>on</strong> wetlands and waterbirds in the mid Yangtze Basin, and the uncertain impacts<br />

of further changes <strong>to</strong> the system, it is essential <strong>to</strong> avoid significant changes <strong>to</strong> seas<strong>on</strong>al water levels as well<br />

as timing and the patterns of fluctuati<strong>on</strong> characteristic of <strong>Poyang</strong> <strong>Lake</strong>. If the dam is built, its operati<strong>on</strong><br />

can be guided by hydrologic characteristics of <strong>Poyang</strong> <strong>Lake</strong> over the past decades. Res<strong>to</strong>ring/maintaining<br />

natural fluctuati<strong>on</strong>s is essential <strong>to</strong> maintaining the productivity of the wetlands. Hence, if the dam is <strong>to</strong> be<br />

built, detailed plans for dam operati<strong>on</strong> must be determined early in the design phase of project planning.<br />

Intensive management of small areas such as Dahu Chi can bring substantial benefits and should be<br />

undertaken but such small areas will not be capable of sustaining large number of waterbirds of diverse<br />

foraging guilds over the l<strong>on</strong>g term.<br />

Decisi<strong>on</strong>s about <strong>Poyang</strong> <strong>Lake</strong> need <strong>to</strong> take in<strong>to</strong> account the regi<strong>on</strong>al situati<strong>on</strong>. Bird species bel<strong>on</strong>ging <strong>to</strong><br />

the tuber‐feeding guild, for example, are especially threatened as are the submerged aquatic plants such<br />

as Vallisneria <strong>on</strong> which they depend. <strong>Poyang</strong> <strong>Lake</strong> is likely the last extensive habitat available <strong>to</strong> species<br />

bel<strong>on</strong>ging <strong>to</strong> this foraging guild, and their c<strong>on</strong>servati<strong>on</strong> should be a high priority.<br />

Given the l<strong>on</strong>g‐term decline in most waterbird species, and the loss of extensive habitats in their breeding,<br />

migra<strong>to</strong>ry, and wintering areas, a precauti<strong>on</strong>ary approach needs <strong>to</strong> be applied <strong>to</strong> management of<br />

populati<strong>on</strong>s and habitats for waterbirds and other rare aquatic animals. Where there are knowledge gaps<br />

for species such as Siberian crane or finless porpoise, decisi<strong>on</strong>s should avoid further risks <strong>to</strong> survival of the<br />

species until the needed research can be completed. For example, is there c<strong>on</strong>clusive research<br />

dem<strong>on</strong>strating that the sluice gates when open would effectively allow passage of finless porpoise? For an<br />

endangered and declining species, it is essential not <strong>to</strong> further fragment its populati<strong>on</strong>s.<br />

Due <strong>to</strong> the limited time available <strong>to</strong> the team during their <strong>visit</strong>, it was not possible <strong>to</strong> fully assess the<br />

impacts of the proposed dam <strong>on</strong> the fish and the finless porpoise (Neophocaena phocaenoides<br />

26


asiaeorientalis) that migrate between the Yangtze River and <strong>Poyang</strong> <strong>Lake</strong>. However, the scientific data that<br />

the team has seen indicates that the dam will likely act as a barrier <strong>to</strong> migrati<strong>on</strong> and so have a negative<br />

impact <strong>on</strong> both the populati<strong>on</strong>s of fish (many of which are of ec<strong>on</strong>omic importance) and of the finless<br />

porpoise. This is clearly an area where further review of the scientific literature is needed.<br />

6.4 Policy<br />

6.4.1 Integrated River Basin Management (IRBM) approach<br />

In the early 1980s, the Jiangxi Provincial government embarked <strong>on</strong> the innovative ‘Mountain, River and<br />

<strong>Lake</strong> Development and Management Project’, <strong>to</strong> take a comprehensive approach <strong>to</strong> the sustainable<br />

management and development of the mountains and rivers. In view of the increasing populati<strong>on</strong> and<br />

development pressures in the <strong>Poyang</strong> <strong>Lake</strong> Basin, such an Integrated River Basin Management (IRBM)<br />

approach <strong>to</strong> development in and around <strong>Poyang</strong> <strong>Lake</strong> needs <strong>to</strong> be strengthened. A representative<br />

management committee for implementing this should be established comprising representatives from key<br />

agencies and stakeholders. Models adopted in other countries or regi<strong>on</strong>s could be examined <strong>to</strong> identify<br />

key features for a suitable operating structure for the <strong>Lake</strong>. Examples occur in the Mek<strong>on</strong>g Basin, Chilika<br />

<strong>Lake</strong> in India, the Great <strong>Lake</strong>s in Canada/USA, the Danube River in Europe, and the Okavango and Nile<br />

Basins Rivers in Africa. The <strong>Ramsar</strong> Secretariat could advise <strong>on</strong> suitable examples and organizati<strong>on</strong>s.<br />

Developing links with such organizati<strong>on</strong>s and exchanging informati<strong>on</strong> and experience in managing complex<br />

ecological systems could provide a l<strong>on</strong>g‐lasting and c<strong>on</strong>structive basis for improving envir<strong>on</strong>mental<br />

management.<br />

An independent technical advisory committee should also be established <strong>to</strong> provide scientific advice <strong>to</strong> the<br />

above menti<strong>on</strong>ed management committee and <strong>to</strong> review the technical informati<strong>on</strong> collected by<br />

researchers and m<strong>on</strong>i<strong>to</strong>ring organizati<strong>on</strong>s. It may be useful <strong>to</strong> include internati<strong>on</strong>al expertise in this<br />

committee, possibly facilitated through the Secretariat of The <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong>.<br />

During the team’s <strong>visit</strong>, they heard representatives from the various Jiangxi government departments<br />

speak about a range of development, health and ecological issues facing <strong>Poyang</strong> <strong>Lake</strong> and the people living<br />

in and around it. Many of the representatives then spoke about the need <strong>to</strong> c<strong>on</strong>struct the proposed dam<br />

as a soluti<strong>on</strong> <strong>to</strong> addressing those issues. However, there are likely <strong>to</strong> be a range of alternative soluti<strong>on</strong>s<br />

which can also be effective and these should also be investigated.<br />

6.4.2 Assessment of the effect of the proposed <strong>Poyang</strong> <strong>Lake</strong> hydraulic project<br />

The Jiangxi Provincial government should c<strong>on</strong>duct Strategic Envir<strong>on</strong>mental Assessments (SEA) and<br />

Envir<strong>on</strong>mental Impact Assessments (EIA) of all the projects under c<strong>on</strong>siderati<strong>on</strong>. Such assessments should<br />

also be carried out <strong>on</strong> all stages of those projects, i.e. at the planning phase, <strong>site</strong> locati<strong>on</strong> phase, design<br />

phase and operati<strong>on</strong> phase.<br />

6.4.3 Scientific support for development of policy<br />

Following guidelines established under the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong>, the process <strong>to</strong> assess the effect of the<br />

proposed hydraulic project should be independent, balanced and transparent, <strong>to</strong> take in<strong>to</strong> account the<br />

views of the various government departments, scientists and experts, and other relevant stakeholders. At<br />

the end, the decisi<strong>on</strong> making process would benefit from hearing the wide range of comments, and<br />

stakeholders would be more supportive of the eventual outcome.<br />

As a result, it is proposed that when the six expert teams have completed their draft reports <strong>on</strong> their<br />

particular investigati<strong>on</strong>s, that a meeting be held with the interested scientific community. Each of the<br />

27


teams would present the results of their report and the audience be allowed <strong>to</strong> provide comments.<br />

Similarly before the final report from integrati<strong>on</strong> of all the reports from the six teams is finalized, a sec<strong>on</strong>d<br />

open meeting should be held when comments from the scientific audience will be permitted.<br />

6.4.4 Other obligati<strong>on</strong>s under the <strong>Ramsar</strong> C<strong>on</strong>venti<strong>on</strong><br />

During the <strong>visit</strong>, many scientists and government representatives repeated that <strong>Poyang</strong> <strong>Lake</strong> is drying out<br />

earlier and for l<strong>on</strong>ger periods each winter. This change appears <strong>to</strong> be the basis for the argument <strong>to</strong><br />

c<strong>on</strong>struct the proposed water c<strong>on</strong>trol structure at the mouth of <strong>Poyang</strong> <strong>Lake</strong>. If so, then the ecological<br />

character of the lake and the <strong>Ramsar</strong> <strong>site</strong> is changing and the State Forestry Administrati<strong>on</strong> should notify<br />

the Secretariat formally of this change as required under Article 3.2 of the C<strong>on</strong>venti<strong>on</strong>.<br />
