Context: The Edwin B. Forsythe National Wildlife Refuge is a United States National Wildlife Refuge located in southern New Jersey along the Atlantic coast north of Atlantic City, in Atlantic and Ocean counties.  The refuge was created in 1984 out of two existing refuge parcels created to protect tidal wetland and shallow bay habitat for migratory water birds.  The Barnegat Division (established in 1967) is located in Ocean County on the inland side of Barnegat Bay.  The Brigantine Division (established in 1939) is located approximately 10 miles (16 km) north of Atlantic City along the south bank of the mouth of the Mullica River.  The two divisions are separated by approximately 20 miles (32 km).  The refuge is located along most active flight paths of the Atlantic Flyway, making it an important link in the network of national wildlife refuges administered nationwide by the U.S. Fish and Wildlife Service.  Forsythe Refuge is a part of the Hudson River/New York Bight Ecosystem and The New Jersey Coastal Heritage Trail Route.  The refuge is named for Edwin B. Forsythe, conservationist Congressman from New Jersey. Jeremy J. C. Mallinson OBE is a conservationist associated with the Durrell Wildlife Park and Durrell Wildlife Conservation Trust.
