Reef Check is an international non-governmental organization dedicated to the conservation of two reef ecosystems: tropical coral reefs and Californian rocky reefs. The Foundation is headquartered in Los Angeles, California, United States, but uses data from volunteer scuba diver teams in over 80 countries, ranging from Australia, Japan, to even Germany. It is the United Nations’ official coral reef monitoring program.〔(【引用サイトリンク】title=Reef Check Worldwide )〕〔(【引用サイトリンク】title=International Coral Reef Action Network (ICRAN) )〕 ==History== Reef Check first conducted a global survey of coral reef health in 1997. The data confirmed that coral reefs were in crisis due to overfishing, pollution and other human impacts. The published results in 1999 unsettled the coral biologist community, as the extent of impacts were not realized. "The Global Coral Reef Crisis: Trends and Solutions (1997-2001)", a five-year report on coral reefs, was released in 2002 at the World Summit on Sustainable Development in Johannesburg, South Africa. The report used data collected by thousands of volunteers worldwide, and was the first scientific document detailing the decline in coral reef health over a five-year period. In 2005, Reef Check launched its first temperate reef program in California. In 2006, Reef Check conducted 746 reef surveys, ranging from Indo-Pacific areas, the Red Sea and Caribbean Sea. In 2008, in a presentation made at the International Coral Reef Symposium in Fort Lauderdale, Florida, Reef Check Executive Director Gregor Hodgson announced that coral reefs in the Indo-Pacific region have largely recovered from the devastating bleaching event that killed up to 90% of corals on some reefs in 1998. He reported that 10 years later, recovery has occurred more quickly and more completely than expected. Caribbean reefs, however, are losing about 3% living coral every four years due to a combination of human impacts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reef Check」の詳細全文を読む スポンサード リンク
