Great Barrier Reef

AIMS' Long-Term Monitoring Program measures the status and trend of reefs in the Great Barrier Reef World Heritage Area.

Continued coral recovery recorded across two-thirds of the Great Barrier Reef

10 months ago By Main minion

Published today, AIMS’ Annual Summary Report on Coral Reef Condition for 2021/22 shows another year of increased coral cover across much of the Reef.

The increasing frequency of warming ocean temperatures and the extent of mass bleaching events highlights the critical threat climate change poses to all reefs, particularly while crown-of-thorns starfish outbreaks and tropical cyclones are also occurring. Future disturbance can reverse the observed recovery in a short amount of time.

The Great Barrier Reef is home to more than 1,500 types of fish, over 400 kinds of hard corals and dozens of other species.

Australia pledges 1 billion to protect Great Barrier Reef

Prime Minister Scott Morrison unveiled the nearly decade-long conservation package days ahead of a February 1 deadline set by UNESCO to submit a report on the reef's state of conservation, and months after it narrowly avoided being placed on the UN's cultural agency's "danger" list due to the threat of climate change.

“Any additional funding for the environment in Australia is welcome, as it is severely under-resourced. However, handing out cash for the Great Barrier Reef with one hand, while funding the very industry – fossil fuels – that’s driving devastating climate impacts like marine heatwaves and coral bleaching, means they are adding to the very problem they are claiming they want to fix.”

— Climate Councillor, climate scientist and Distinguished Professor of Biology at Macquarie University, Professor Lesley Hughes

Coral 'skyscraper' discovered off Australia

2 years ago By Scott Bennett

Researchers in Australia have uncovered a massive “detached” coral reef off the Queensland coast, the first of its kind to be discovered in more than 120 years. The discovery was made about 80 kilometres east of Cape Grenville, approximately 150 kilometres south of the tip of the Cape York Peninsula.

Great Barrier Reef's saviour—a giant snail?

5 years ago By Sum Won

A giant sea snail may turn out to be another line of defense against the destructive crown-of-thorn starfish that is currently plaguing Australia’s Great Barrier Reef.

Called the Pacific triton sea snail (Charonia tritonis), it can grow up to about 50 to 60cm and is indigenous to Australian waters. More importantly, the crown-of-thorn starfish happens to be part of its natural diet. However, the sea snail is currently endangered due to the consumer demand for their shells.

The relative abundance of sharks was significantly higher in non-fished sites

Healthy reefs have more sharks

8 years ago By Main minion

The present study examined shark distribution patterns, species-habitat associations, and marine reserve use with baited remote underwater video stations (BRUVS) along the entire Great Barrier Reef Marine Park (GBRMP) over a ten-year period.

Overall, researchers recorded 21 different shark species. The relative abundance of sharks was significantly higher in non-fished sites in the GBR Marine Park no-fishing zones relative to fished sites.
