This project will continue a unique data set that documents long-term trends in coral reef communities of the Great Barrier
Reef (GBR). In 2012-13 and 2014-15 the LTMP will resurvey the ‘core’ reefs that have been surveyed since 1992.
The AIMS LTMP has made intensive surveys of 47 ‘core’ reefs since 1992. The survey reefs are stratified by latitude and position
across the GBR lagoon so as to give broad geographic coverage. Divers make intensive surveys on marked transects in one
habitat on the selected reefs and the perimeters of the reefs are also surveyed by manta tow to assess densities of crown-of-thorns
starfish and estimate reef-wide coral cover. Additional reefs are surveyed by manta tow to give broad-scale information
on coral cover, bleaching, coral disease, etc., as well as crown-of-thorns starfish outbreaks. Because of concern for their
conservation status, reef sharks will also be counted during manta tow surveys.
Outcomes of this project include: Updates on status and temporal trends in coral, fish and crown-of-thorns starfish populations
on survey reefs, report on recovery rates and resilience of reefs after cyclones in 2009-2011, report on crown-of-thorns
starfish outbreaks on the GBR and publications on coral and fish dynamics in relation to management and environmental
