The "Caumsett Bird Conservation Area" was established in 2006 and comprises approximately 1,255 acres (5.08 km2) of the state park, two-thirds of which is forested. The remainder includes a variety of habitats, such as salt marsh and maritime beach. The designated area protects high-quality habitat that supports breeding populations of several species listed as threatened or endangered in New York State, including piping plovers, common terns, and least terns; many additional migratory species also make use of the protected landscape.[12]
