Jamaica Bay is an 18,000-acre wetland estuary surrounded by the Rockaway Peninsula to the South, Brooklyn to the West, and Queens to the East, and includes approximately 10,000 acres of parkland managed by the National Park Service and NYC Parks as an urban national park. Comprising an area almost equal to the size of Manhattan, the bay consists of numerous islands, a labyrinth of waterways, meadowlands, and two freshwater ponds. The wetlands provide a unique environment for both wildlife preservation and urban recreation. Enclosed by the Rockaway Peninsula and protected from the Atlantic Ocean, the region currently hosts over 325 species of birds, 50 species of butterflies, and 100 species of finfish. A favorite stop for migratory waterfowl, the area is an integral part of the larger, regional ecosystem.
