Researchers found 16% of coral species have not been seen for many years. This finding is alarming, because local extinctions suggest global extinctions may be looming.

The federal government’s new funding aims to spread the net wide in investigating possible ways to protect the Great Barrier Reef’s corals. Winning this battle will require a wide range of weapons.
Some reefs are strong sources of coral larvae.
A new study identifies dozens of individual reefs on the Great Barrier Reef that are especially important for coral larvae dispersal and which could help the entire ecosystem bounce back.
Hundreds of thousands of crown-of-thorns starfish have invaded North Queensland, devastating reefs.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
The Great Barrier Reef’s health has declined in recent years.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

To fix pollution on the Great Barrier Reef, some farming practices will have to change.
The land may be dry, but Western Australia’s waters are full of life.
The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
During an outbreak, crown-of-thorns starfish can number in the millions and decimate coral reefs.

Crown-of-thorns starfish are one of the biggest threats to the Great Barrier Reef. Since 1985, the Great Barrier Reef has lost half its coral cover, with almost half of this coral loss due to the crown-of-thorns…

On Monday, the Coalition announced its plan for the Great Barrier Reef, including a A$40m trust-fund to target threats to the Reef such as Crown of Thorns starfish and runoff from agriculture. The promises…
Extreme weather events, such as Cyclone Yasi, are damaging the Great Barrier Reef.
The Great Barrier Reef has lost half its coral cover in the last 27 years, and it could halve again by 2022 say researchers from the Australian Institute of Marine Science. A study published today in the…
