About NOAA's Protected Places





Conserving coastal places provides economic benefits to local communities. These communities rely on dollars spent on activities such as recreation and tourism. NOAA works to conserve marine areas — and preserve the economic benefits of these special places to local communities — through its coastal management and place-based conservation programs. These include Coastal Zone Management, the Coastal and Estuarine Land Conservation Program, the National Estuarine Research Reserve System, National Marine Sanctuaries, and the Coral Reef Conservation Program. NOAA will continue to express the inherent value and national interest in conserving these special places for the American public.
