<strong>Status</strong> <strong>of</strong> <strong>Coral</strong> <strong>Reefs</strong> <strong>of</strong> Australasia<br />
MONITORINGOFTHEGBR<br />
As a federal government research institute adjacent to <strong>the</strong> Great Barrier Reef, <strong>the</strong><br />
Australian Institute <strong>of</strong> Marine Science (AIMS) is concerned with studying many aspects<br />
<strong>of</strong> coral reefs, but one specific task is <strong>the</strong> continued assessment <strong>of</strong> <strong>the</strong> health <strong>of</strong> <strong>the</strong><br />
reefs: <strong>the</strong> AIMS Long-term Monitoring Program on <strong>the</strong> GBR. The objective is to monitor<br />
regional status and trends <strong>of</strong> selected organisms on <strong>the</strong> reefs with <strong>the</strong> results<br />
contributing significantly to fulfilling <strong>the</strong> reporting requirements associated with <strong>World</strong><br />
Heritage listing <strong>of</strong> <strong>the</strong> GBR. Each year, 48 ‘core’ reefs are visited, selected on <strong>the</strong>ir<br />
position across <strong>the</strong> continental shelf (<strong>the</strong>re are very clear differences in reef<br />
communities on <strong>the</strong> coast – ocean gradient) and by latitude. Marked permanent<br />
transects are placed in one habitat, <strong>the</strong> NE slopes <strong>of</strong> <strong>the</strong> reefs. These are surveyed for<br />
benthic organisms using underwater video and 191 species <strong>of</strong> reef fishes are counted<br />
on <strong>the</strong> transects. The perimeters <strong>of</strong> <strong>the</strong> core reefs and <strong>of</strong> about 50 o<strong>the</strong>r reefs are<br />
surveyed by manta tow to record densities <strong>of</strong> COTS and to estimate reef-wide coral<br />
cover. Extensive quality control procedures are in place, and outlined in Standard<br />
Operating Procedure documents (SOPs) that are reviewed regularly. Observers are<br />
cross-calibrated at frequent intervals, and specialised data-entry programmes are used<br />
to help extract information from <strong>the</strong> video records and to check <strong>the</strong> data as <strong>the</strong>y are<br />
entered. These include statistical data checking for unlikely values. Methodological<br />
studies are also an important part <strong>of</strong> <strong>the</strong> program. Much emphasis is given to reporting<br />
via <strong>the</strong> Internet [www.aims.gov.au/reef-monitoring]. Preliminary reports emphasising<br />
COTS are posted within a few days <strong>of</strong> each survey, and interactive data summaries are<br />
available, which include <strong>the</strong> most up to date information. There are pages dealing<br />
with particular issues such as COTS and coral bleaching. The program produces<br />
annual <strong>Status</strong> Reports, which are also available via <strong>the</strong> Internet along with SOPs and<br />
o<strong>the</strong>r documentation. Many aspects <strong>of</strong> reporting, particularly statistical analyses and<br />
graphs, are generated automatically, and <strong>the</strong> program produces scientific papers<br />
describing <strong>the</strong> large scale patterns revealed in <strong>the</strong> monitoring data. The monitoring<br />
team have also been involved in considerable training <strong>of</strong> people in many countries for<br />
<strong>the</strong> GCRMN. Staff <strong>of</strong> <strong>the</strong> program includes 6 graduate biologists in <strong>the</strong> field team, a<br />
database administrator, a biostatistician and a coral reef biologist; all this costs more<br />
than US$1.5 million per year.<br />
large area and <strong>the</strong>re is a project linking real-time records from automatic wea<strong>the</strong>r stations<br />
run by AIMS with NOAA-NESDIS satellite SST data as part <strong>of</strong> <strong>the</strong> ‘Bleaching Hotspots’<br />
program to identify locations at risk <strong>of</strong> coral bleaching.<br />
There are also monitoring programmes at Ningaloo Reef, Scott Reef and <strong>the</strong> Rowley Shoals,<br />
Lord Howe and <strong>the</strong> Solitary Is. There is a wide gap across much <strong>of</strong> far nor<strong>the</strong>rn Australia<br />
from <strong>the</strong> nor<strong>the</strong>rn quarter <strong>of</strong> <strong>the</strong> GBR to <strong>the</strong> Pilbarra in Western Australia where <strong>the</strong>re is no<br />
monitoring and little baseline information. Australian government funding policies favour<br />
community-based monitoring programmes in both terrestrial and marine environments.<br />
While this approach has a number <strong>of</strong> potential benefits, it remains untested as a method <strong>of</strong><br />
producing reliable long-term data on reef ecosystems.<br />
