Australia’s Barrier Reef loses half of coralPublished On: Mon, Oct 1st, 2012 | Environment | By IANS
Australia’s Great Barrier Reef, the world’s largest coral reef system, has lost half of its coral cover in the past 27 years, a study revealed Monday.
Three factors were particularly responsible for the loss. Intense tropical cyclones, coral-consuming crown-of-thorns starfish and coral bleaching events, Xinhua reported.
“This finding is based on the most comprehensive reef monitoring programme in the world,” said Peter Doherty, a scholar at the Australian Institute of Marine Science.
“The programme started broad-scale surveillance of more than 100 reefs in 1985 and from 1993 it has incorporated more detailed annual surveys of 47 reefs,” he said.
