The Northwestern Hawaiian Islands (NWHI) consist of small islands, atolls, submerged banks, and reefs, which stretch for more than 2,000 km northwest of the main Hawaiian Islands. On June 15, 2006, the President of the United States designated the Northwestern Hawaiian Islands (NWHI) a national monument, enabling nearly 140,000 square miles of the NWHI to receive our Nation's highest form of marine environmental protection. The coral reefs of the NWHI may be the healthiest and most undisturbed of the United States reefs, and unlike most other present-day coral reefs, they comprise possibly the last, large-scale, apex predator-dominated coral reef ecosystem on Earth. The NWHI coral reefs and associated habitats harbor more than 7,000 species, many of which are rare, threatened, or endangered; many are endemic, found nowhere else on Earth. Many more remain unidentified or even undiscovered to science.

Appearing as solitary forms in the fossil record more than 400 million years ago, corals are extremely ancient animals that evolved into modern reef-building forms over the last 25 million years.

The NOAA Coral Reef Conservation Program (CRCP) is a partnership between the NOAA Line Offices that work on coral reef issues: the National Ocean Service, the National Marine Fisheries Service, the Office of Oceanic and Atmospheric Research, and the National Environmental Satellite, Data and Information Service. The CRCP brings together expertise from across NOAA for a multidisciplinary approach to managing and understanding coral reef ecosystems.
