Parker River National Wildlife Refuge was established in 1942 to provide feeding, resting, and nesting habitat for migratory birds. The refuge occupies 4,662 acres on the southern two-thirds of Plum Island, a barrier island on the Northeast coast of Massachusetts, and is administered by the US Fish and Wildlife Service, a federal agency. Parker River is one of over 540 Refuges in the National Wildlife Refuge System, a national network of lands dedicated to "wildlife first."
The beach closes on April 1, and reopens in mid-summer due to the needs of the piping-plover, a nationally recognized threatened species of sea birds.
