context_page_description: Everglades National Park is an American national park that protects the southern twenty percent of the original Everglades in Florida. The park is the largest tropical wilderness in the United States, and the largest wilderness of any kind east of the Mississippi River. An average of one million people visit the park each year. Everglades is the third-largest national park in the contiguous United States after Death Valley and Yellowstone. UNESCO declared the Everglades & Dry Tortugas Biosphere Reserve in 1976, and listed the park as a World Heritage Site in 1979, while the Ramsar Convention included the park on its list of Wetlands of International Importance in 1987. Everglades is one of only three locations in the world to appear on all three lists.
  Most national parks preserve unique geographic features; Everglades National Park was the first created to protect a fragile ecosystem. The Everglades are a network of wetlands and forests fed by a river flowing 0.25 miles per day out of Lake Okeechobee, southwest into Florida Bay.
context_section_description: Cypress trees are conifers that are adapted to live in standing fresh water. They grow in compact structures called cypress domes and in long strands over limestone. Water levels may fluctuate dramatically around cypress domes and strands, so cypresses develop "knees" that protrude from the water at high levels to provide oxygen for the root systems. Dwarf cypress trees grow in drier areas with poorer soil. Epiphytes, such as bromeliads, Spanish moss (Tillandsia usneoides), orchids and ferns grow on the branches and trunks of cypress trees. Everglades National Park features twenty-five species of orchids. Tall cypress trees provide excellent nesting areas for birds including wild turkey (Meleagris gallopavo), ibis, herons, egrets, anhingas (Anhinga anhinga), and belted kingfisher (Megaceryle alcyon). Mammals in cypress regions include white-tailed deer, squirrels, raccoons, opossums, skunks, swamp rabbits, river otters (Lontra canadensis), and bobcats, as well as small rodents.
  Mangrove trees cover the coastlines of South Florida, sometimes growing inland depending on the amount of salt water present within the Everglades ecosystems. During drier years when less fresh water flows to the coast, mangroves will appear among fresh water plants. When rain is abundant, sawgrass and other fresh water plants may be found closer to the coast. Three species of mangrove trees—red (Rhizophora mangle), black (Avicennia germinans), and white (Laguncularia racemosa)—can be found in the Everglades. With a high tolerance of salt water, winds, extreme tides, high temperatures, and muddy soils, mangrove trees are uniquely adapted to extreme conditions. They act as nurseries for many marine and bird species. They are also Florida's first defense against the destructive forces of hurricanes, absorbing flood waters and preventing coastal erosion. The mangrove system in Everglades National Park is the largest continuous system of mangroves in the world.
  Within the Florida mangrove systems live 220 species of fish, and a variety of crabs, crayfish, shrimp, mollusks, and other invertebrates, which serve as the main source of food for many birds. Dozens of bird species use mangroves as nurseries and food stores, including pelicans, grebes, tricolored herons (Egretta tricolor), gulls, terns, hawks and kites, and arboreal birds like mangrove cuckoos (Coccyzus minor), yellow warblers (Dendroica petechia), and white-crowned pigeons (Patagioenas leucocephala). The mangroves also support 24 species of amphibians and reptiles, and 18 species of mammals, including the endangered green turtle (Chelonia mydas), hawksbill turtle (Eretmochelys imbricata), and West Indian manatee (Trichechus manatus).
