Many near-shore reefs on Guam have been degraded by natural and human impacts, especially sedimentation, tourism and overharvesting. The reefs on Guam’s offshore banks and coral reef fisheries in the CNMI appear to be generally in good condition.
The Mariana Archipelago Regional Ecosystem Advisory Committee on Guam has made recommendations on a variety of non-fishing impacts, such as limited coastal access, marine protected areas, water quality, tourism, overdevelopment and military buildup. The relocation of about 8,000 military personnel and their families from Okinawa to Guam along with 12,000 to 15,000 construction workers will have a significant impact on the ecosystem. Increased military training will likely occur in the CNMI as part of the military realignment.
