Research Needed On Imperiled Coral Ecosystems

Coral ecosystems are being imperiled at regional to global scales by over fishing, climate change, disease, and exposure to excess sediments, nutrients and contaminants. Scientists believe that recent changes in reef systems worldu"wide are unprecedented, according to a report released by the U.S. Geological Survey (USGS) that summarizes these threats and outlines important research actions needed over the next five years to more accurately forecast future conditions and to better understand and manage change. "Coral ecosystems contribute an estimated $30 billion to the global economy, but they are being transformed rapidly by a combination of local, regional, and global stressors," said Gary Brewer, USGS Eastern Region Ocean Science Coordinator. "The USGS has developed a robust research plan that addresses the threats that coral ecosystems are facing," said Brewer...
