Supawna Meadows National Wildlife Refuge is located along the Delaware River estuary just north of the Salem River in Salem County, NJ. The Delaware Bay and estuary is recognized as a wetlands of international importance and an international shorebird reserve. The refuge currently owns approximately 2,800 acres within the 4,600 acre approved boundary. The brackish tidal marshes that make up nearly 80 percent of the refuge provide waterfowl with an important feeding and resting area, particularly during the fall and spring migrations. Black ducks, mallards and northern pintails are common winter visitors. Sandpipers and other shorebirds use the refuge marshes as a feeding area during the summer as well as during the spring and fall migrations. Delaware's nearby Pea Patch Island Rookery hosts over 6,000 pairs of nine species, making it the largest rookery of colonial wading birds on the east coast north of Florida. The refuge marshes provide valuable foraging habitat for these colonial wading birds during the nesting season.

Warblers, sparrows and other migratory birds use the upland areas of the refuge as resting and feeding areas during migration and for nesting during the summer. Thousands of tree swallows forage on the refuge in the late summer. Ospreys, bald eagle, northern harrier, short-eared owl and barn owl nest on the refuge.
