Florida's Everglades National Park was established in 1934 to protect one of the nation's most remarkable and fragile ecosystems, a vast network of marshland, mangrove, and forest.

A great blue heron among the reeds. More than 350 species of birds, 300 species of fish, 50 species of reptiles, and 40 species of mammals call the Everglades home.
American Alligators, a common sight in the Everglades, were once threatened with extinction. By 1987, however, the reptiles had recovered thoroughly enough to be removed from the endangered species list, and they continue to thrive today.
