<strong>Status</strong> <strong>of</strong> <strong>Coral</strong> <strong>Reefs</strong> <strong>of</strong> <strong>the</strong> <strong>World</strong>: <strong>2000</strong><br />
Jurisdictions pertinent to coral reefs are as follows:<br />
American Samoa<br />
<strong>Coral</strong> reefs in American Samoa have been resilient so far to a series <strong>of</strong> natural perturbations,<br />
although a full recovery may take ano<strong>the</strong>r decade. Although <strong>the</strong> message for managers is<br />
that <strong>the</strong> reefs will recover if we ‘do no harm’, we are faced with several examples where<br />
serious harm has been done, particularly over-fishing <strong>of</strong> reef resources, reduced water<br />
quality in populated areas, and loss <strong>of</strong> turtle nesting beaches due to coastal construction.<br />
Additionally, we are faced with climate change with uncertain consequences for local reefs.<br />
Several areas which require fur<strong>the</strong>r work for coral reef conservation are:<br />
• Expand coral reef monitoring efforts and focus <strong>the</strong> objectives. Most monitoring<br />
in American Samoa can be characterised as ‘ecological monitoring’ that tracks<br />
changes in <strong>the</strong> ecosystem over time. These studies have provided valuable<br />
insight, highlighting <strong>the</strong> dynamic nature <strong>of</strong> coral reef systems. From ano<strong>the</strong>r<br />
perspective, however, <strong>the</strong>se studies were not designed to address questions<br />
commonly faced by reef managers: Is over-fishing occurring? Is sediment from<br />
poor land-use practices harming <strong>the</strong> reef? etc. Consequently, it is important at<br />
<strong>the</strong> outset <strong>of</strong> any monitoring program to clearly identify (a) <strong>the</strong> intended users <strong>of</strong><br />
<strong>the</strong> monitoring program, and (b) <strong>the</strong> parameters that should be measured to<br />
provide <strong>the</strong> information that <strong>the</strong>y need. In addition to this management driven<br />
approach, a monitoring program in American Samoa should be: (a) achievable<br />
with local staff, although we recognise that <strong>of</strong>f-island scientific expertise may be<br />
needed to address some issues, (b) stable to rotations <strong>of</strong> technical staff who are<br />
typically hired on 2-year contracts, (c) comparable to o<strong>the</strong>r programmes to <strong>the</strong><br />
degree possible, and (d) open to community input and management.<br />
• Restart monitoring <strong>of</strong> coral reef fisheries. A workshop in American Samoa<br />
identified over-fishing as <strong>the</strong> major problem hindering recovery <strong>of</strong> local reefs<br />
(ASCRTF 1999), so it is essential that basic harvest data be collected to monitor<br />
trends in total catch, catch-per-unit-effort, etc.<br />
• Create a territorial network <strong>of</strong> ‘no-take’ MPAs. There are two issues here: existing<br />
Marine Protected Areas are not yet adequately enforced; and ‘no-take’ MPAs are<br />
needed in <strong>the</strong> main islands where over-fishing is occurring.<br />
• Improve land-use practices that reduce water quality. Despite welcome<br />
improvements in water quality in Pago Pago Harbour, <strong>the</strong>re has not been a full<br />
recovery <strong>of</strong> coral reefs, swimming is not safe, nor are fish safe to eat. A stepwise<br />
recovery plan should be implemented to build on progress, and harbour<br />
fish and sediments need to be tested for toxicity at regular intervals.<br />
Improvements in land-use practices and waste disposal are needed to reduce<br />
sedimentation and pollution impacts on coral reefs.<br />
Nor<strong>the</strong>rn Marianas<br />
The reefs in <strong>the</strong> CNMI outside <strong>of</strong> <strong>the</strong> main population and development centres are in<br />
relatively good condition, but more surveys and quantitative data are needed. Greater<br />
effort has been made in <strong>the</strong> last few years to establish a long-term marine monitoring<br />
program, with ongoing monitoring at a number <strong>of</strong> sites on Saipan, Tinian and Rota, and<br />
