Parker River and Great Bay National Wildlife Refuge

Parker River National Wildlife Refuge is located on Plum Island, a barrier island along the coast of northern Massachusetts. The mix of habitats—including salt marsh, salt pannes, maritime shrubland, and beach dunes—makes the location especially important for migratory birds. One of the main focuses of the Refuge is to restore habitats and ecosystems to be more resilient to climate change, particularly for salt marshes in the Great Marsh.

Great Bay National Wildlife Refuge is oak hickory forest with many forested wetland and tidal estuary tucked inland just west of Portsmouth, New Hampshire. Here, fresh riverine waters meet salty oceanic waters allowing a wide variety of plant and animal life to flourish. The Refuge is another important stopping ground for migrating birds to feed, shelter, and in some cases breed.
