The Jug Bay Wetlands Sanctuary is located along the tidal Patuxent River in southern Maryland. It was established in 1985 and is operated by the Anne Arundel County Department of Recreation and Parks. It includes more than 1,500 acres (6.1 km²) of tidal freshwater wetlands, forests, meadows and fields. The wetlands, with large stands of aquatic plants including wild rice, are home to many birds, fish, reptiles, and mammals. Miles of trails and boardwalks traverse a variety of habitats and provide glimpses into the rich history of the region. In 1990, the Sanctuary became a component of the Chesapeake Bay National Estuarine Research Reserve System.
