Deer Creek Marsh lies at the southern limit of a 17-mile long region of sandy barrier beaches that protect coastal lagoons and marshes; the region is unusual geologically and is important as habitat for many species.[1][2] Deer Creek Marsh WMA is part of the Eastern Lake Ontario Marshes Bird Conservation Area, along with Black Pond and Lakeview WMAs and the Sandy Pond Beach Unique Area.[3]
