Site description The Upper Bay of Panama includes very extensive tidal mudflats (11,000 ha) up to 3 km wide, from Costa del Este just east of Panama City to the Ensenada de Corral at the mouth of the La Maestra River 70 km to the east. Near Panama City the site borders heavily urbanized and suburban areas, while the eastern part is relatively remote and difficult of access except by boat. Rivers draining into the bay include the Bayano (by far the largest), Juan Díaz, Cabra, Pacora, Chico, Pasiga, and La Maestra. On the landward side the site is contiguous with Tocumen Marsh and La Jagua, which are national-level IBAs, and merges with the Chimán Wetlands IBA to the east.
