Executive Summary<br />
parts <strong>of</strong> Fiji and <strong>the</strong> Solomon Islands. Human impacts on <strong>the</strong>se reefs are steadily increasing<br />
but still concentrated at a few sites per country, mainly around <strong>the</strong> capital cities and in<br />
lagoons. However, most reefs are still healthy with few real problems, except for some<br />
over-fishing for subsistence and small-scale commercial activities. Most reefs are protected<br />
by <strong>the</strong> influence <strong>of</strong> <strong>the</strong> Pacific Ocean, which both dilutes nutrient and toxic pollution and<br />
removes sediments. Recent political instability in <strong>the</strong> Solomon Islands and Fiji, has delayed<br />
conservation efforts for coral reefs e.g. <strong>the</strong> special marine science unit <strong>of</strong> <strong>the</strong> University <strong>of</strong><br />
<strong>the</strong> South Pacific, and <strong>the</strong> ICLARM aquaculture centre have moved <strong>of</strong>f <strong>the</strong> Solomon Islands<br />
awaiting developments. An active coral reef monitoring network is being established at <strong>the</strong><br />
University <strong>of</strong> <strong>the</strong> South Pacific in Suva and in smaller campuses in o<strong>the</strong>r countries, but most<br />
nations lack <strong>the</strong> capacity to implement long-term monitoring. Most nations have not<br />
declared key areas as marine protected areas, and have little capacity for integrated coral<br />
reef management.<br />
Sou<strong>the</strong>ast Pacific<br />
This region also escaped major climate related coral bleaching in 1997-98 and <strong>2000</strong>, such<br />
that most <strong>of</strong> <strong>the</strong> reefs remain healthy with few anthropogenic threats. Similar to o<strong>the</strong>r areas<br />
in <strong>the</strong> Pacific, most human impacts are concentrated around <strong>the</strong> major centres <strong>of</strong><br />
population and within enclosed lagoons. Considerable shoreline modification on <strong>the</strong>se<br />
islands has resulted in damage to <strong>the</strong> nearshore reefs, but <strong>the</strong> outer reefs facing <strong>the</strong> ocean<br />
show no real impacts. Fishing pressures are increasing, threatening some coral reefs, and<br />
<strong>the</strong>re are increasing conflicts between fishers and tourist operators. Integrated management<br />
planning is needed to improve <strong>the</strong> design, location and management <strong>of</strong> tourist resorts and<br />
to manage <strong>the</strong> rapid growth <strong>of</strong> <strong>the</strong> black pearl culture in some lagoons <strong>of</strong> <strong>the</strong> Cook Islands<br />
and French Polynesia. While <strong>the</strong>re has been active coral reef monitoring in French Polynesia,<br />
such efforts are only beginning in <strong>the</strong> o<strong>the</strong>r countries. The whole region will benefit from a<br />
programme <strong>of</strong> training and monitoring at <strong>the</strong> marine station on Moorea with assistance from France.<br />
Nor<strong>the</strong>ast (American) Pacific<br />
This region contains <strong>the</strong> bulk <strong>of</strong> coral reefs under US control with 2 distinct regions: <strong>the</strong><br />
main islands <strong>of</strong> Hawaii; and scattered islands and atolls throughout <strong>the</strong> Pacific. Strong<br />
population and economic growth in <strong>the</strong> Hawaiian islands is resulting in considerable local<br />
damage to reefs around <strong>the</strong> major centres and tourist operations, whereas all reefs are<br />
subjected to high and increasing fishing pressures from both indigenous and tourist fishers.<br />
Collecting for <strong>the</strong> aquarium trade has cause major depletion <strong>of</strong> stocks <strong>of</strong> high value species.<br />
There are currently active measures to monitor <strong>the</strong> reefs throughout <strong>the</strong> main islands, and<br />
plans are being developed for considerably improved management <strong>of</strong> coral reef resources,<br />
however, local development pressures will make it difficult to achieve a target <strong>of</strong> 20% <strong>of</strong><br />
areas under protection. In contrast, <strong>the</strong> scattered islands are under minimal anthropogenic<br />
pressures and none experienced climate related bleaching in 1998. The prognosis for <strong>the</strong>se<br />
reefs into <strong>the</strong> immediate future is good, and it would be considerably enhanced by a<br />
greater awareness <strong>of</strong> sustainable management by policy makers.<br />
The American Caribbean<br />
The increase in activity catalysed by <strong>the</strong> formation <strong>of</strong> <strong>the</strong> US <strong>Coral</strong> Reef Task Force means<br />
that awareness has been raised in <strong>the</strong> islands <strong>of</strong> Puerto Rico and <strong>the</strong> US Virgin Islands to<br />
overcome serious problems <strong>of</strong> over-fishing and damage to coastal nursery areas <strong>of</strong><br />
