Supawna Meadows National Wildlife Refuge preserves a protected wetland landscape in southwestern New Jersey within the Delaware River estuary. Covering an approved boundary of about 4,600 acres, with roughly 3,000 acres owned, it is made up largely of brackish tidal marshes and coastal forests that are vital to birds traveling the Atlantic flyway. Waterfowl, shorebirds, warblers, sparrows, tree swallows, ospreys, bald eagles, harriers, and owls all use its habitats. Its marshes also provide important foraging grounds for birds from the major rookery on nearby Pea Patch Island, underscoring the refuge’s role in protecting one of Delaware Bay’s most important bird areas.
