GBR Park Authority 5-Year Report Downgrades Reef Outlook From "Poor" To "Very Poor"
CANBERRA, Australia (AP) — The government agency that manages Australia's Great Barrier Reef has downgraded its outlook for the corals' condition from "poor" to "very poor" due to warming oceans.
The Great Barrier Reef Marine Park Authority's condition report, which is updated every five years, is the latest bad news for the 345,400 square kilometer (133,360 square miles) colorful coral network off the northeast Australian coast as climate change and coral bleaching take their toll.
The report issued Friday finds the greatest threat to the reef remains climate change. The other threats are associated with coastal development, land-based water runoff and human activity such as illegal fishing. "Significant global action to address climate change is critical to slowing the deterioration of the reef's ecosystem and heritage values and supporting recovery," the report said. "Such actions will complement and greatly increase the effectiveness of local management actions in the Reef and its' catchment."
The report is the agency's third and tracks continuing deterioration since the first in 2009. The deterioration in the reef's outlook mostly reflects the expanding area of coral killed or damaged by coral bleaching. The report said the threats — which include the star-of-thorns starfish that prey on coral polyps — are "multiple, cumulative and increasing."
