Fishing pressures, changing ocean conditions, and pollution are just some of the many stressors on marine life within coral reef ecosystems. Researchers identified the following biological indicators to assess the condition of coral reefs and associated reef fish communities.
Coral reefs – coral diversity, distribution, abundance, colony size, and condition Data are collected through diving surveys of shallow-water (0-30 meters) areas. Scientists and coastal managers then use these data to evaluate coral reef and fish population management strategies, document endangered or invasive marine species, and assist with local monitoring efforts.
NCRMP monitors in the Atlantic, Caribbean, and Gulf of America on a two year cycle. Typically Florida and the Flower Garden banks are monitored in even years, and Puerto Rico and the U.S. Virgin Islands are monitored in odd years.
NCRMP monitors in the Pacific Islands on a three year cycle. Typically Hawaii and the Northwest Hawaiian Islands in year one, Guam and the Commonwealth of the Northern Mariana Islands in year two, and American Samoa and the Pacific Remote Islands Area in year three.
