The NOAA Coral Reef Conservation Program has released status reports for coral reefs in the Pacific U.S. states and territories - American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, Hawaiian Archipelago, and the Pacific Remote Islands. The status reports for the Pacific U.S. states and territories range from "Good" in American Samoa and the Pacific Remote Islands to "Fair" in the Commonwealth of the Northern Mariana Islands, Guam, and Hawaii.

The status reports provide an overall snapshot of coral reef ecosystem conditions based on four indicator groups: coral and algae, fish, climate, and human connections. They show the condition of coral reefs in remote, uninhabited areas to be generally better than reefs near human populations which is likely due to water quality issues and impacts from fishing and human use. Reefs in remote, uninhabited areas are still vulnerable to global threats from climate change and their scores reflect these impacts.

Coral reefs rival the biodiversity of tropical rainforests, and they are among the most culturally significant and economically valuable ecosystems on Earth. In the United States, coral reefs provide billions of dollars in food, jobs, recreation and tourism, and coastal protection. However, they face an increasing number of threats from pollution, unsustainable fishing practices, climate change and ocean acidification, and more.

The status reports were developed by the National Coral Reef Monitoring Program, an integrated and focused monitoring effort with partners across the United States. They reports reflect data collected from 2012 to 2017.
