Site description This site includes San Lorenzo National Park, plus adjacent forested areas. The lower Chagres River runs through the middle of the area, and the terrain is broken by many small streams flowing into the Chagres or the Caribbean Sea. This area was formerly the U.S. military base of Ft. Sherman. It includes the World Heritage site of colonial Fort San Lorenzo.

Key Biodiversity The site is important for migratory raptors, with 120,282 Turkey Vultures, 80,372 Broad-winged Hawks, and 60,800 Swainson's Hawks have been counted on autumn migration. The globally near-threatened Plumbeous Hawk and Great Curassow occur. Several nationally threatened species are also found, notably Rufous-necked Wood-Rail, Colombian Crake and Spotted Rail, which are known from only a few sites in Panama. A few endemics of the Central American Caribbean Slope and Darien Lowlands EBAs also occur.

Non-bird biodiversity: Mammals recorded or probably present include Water Opossum, Central American Wooly Opossum, Silky Anteater, Tricolored Bat, Geoffroy's Tamarin, Western Night Monkey, Panamanian Spiny Pocket-Mouse, Capybara, Crab-eating Raccoon, Olingo, Neotropical River Otter, Ocelot, Margay, Jaguarundi, Jaguar, Baird's Tapir and West Indian Manatee.
