Plum Bank Wildlife Management Area
๐๐๐ Coastal Marsh โ Salt marsh habitat along Long Island Sound’s shoreline
Plum Bank Wildlife Management Area protects salt marsh habitat along the Long Island Sound shoreline. These coastal marshes are among the most productive ecosystems on the Eastern Seaboard โ producing more biomass per acre than most agricultural fields. The marsh supports fiddler crabs, ribbed mussels, and spawning fish that form the base of the Sound’s food web.

About Plum Bank
Plum Bank Wildlife Management Area in Old Saybrook protects coastal marsh and upland habitat along Long Island Sound. The area provides important habitat for saltmarsh sparrows โ one of the most endangered songbirds in North America, found only in the tidal marshes of the Atlantic coast. Osprey hunt over the marsh while diamondback terrapins nest on sandy ridges.
Things to Do
Birdwatching for rare saltmarsh sparrows and osprey, hunting (waterfowl seasonal), kayaking through tidal creeks, and wildlife photography. The marsh is one of the best coastal birding spots in the Old Saybrook area.
Insider Tips
Coastal birding: Plum Bank’s shoreline location makes it a prime stopover during fall shorebird migration (August-September). Pro tip: Bring a spotting scope for distant shorebirds on the mudflats at low tide. Timing: Visit 2 hours before low tide for the best shorebird viewing as birds follow the receding water.
Best Time to Visit
Late summer/fall: Shorebird migration peaks August-September. Winter: Sea ducks and loons offshore. Spring: Horseshoe crab spawning (May) and osprey return. Summer: Saltmarsh sparrow nesting โ one of the most endangered birds in North America.

Wildlife & Nature
Plum Bank WMA provides coastal habitat along Connecticut’s Long Island Sound shoreline โ where salt marsh, mudflat, and upland forest meet. This ecotone (habitat transition zone) supports extraordinary species diversity. Saltmarsh sharp-tailed sparrows โ now called saltmarsh sparrows โ are among the most endangered songbirds in North America, nesting exclusively in tidal marshes along the Atlantic coast. Their nests, built just above high tide, are increasingly flooded as sea levels rise โ scientists estimate the species could be extinct by 2050 without intervention. Ospreys and herons feed in the marsh channels. Ribbed mussels filter thousands of gallons of water daily, improving water clarity and quality in the Sound.
