The United States Congress designated the Florida Keys Wilderness (map
) in 1975 and it now has a total of 6,197 acres
All of this wilderness is located in Florida
and is managed by the Fish and Wildlife Service.
Florida Keys Wilderness consists of many islands off shore of the main chain of non-Wilderness Keys that are bisected by US 1. These islands are administered by the Fish and Wildlife Service as part of National Key Deer Refuge, Key West National Wildlife Refuge, and Great White Heron National Wildlife Refuge. They protect a seemingly endless expanse of sea, sky, and islands between the Gulf of Mexico and the Atlantic Ocean south of Florida's southern mainland coast. Although beaches exist on some of the islands, tangles of mangroves make access to most islands difficult. Furthermore, most of the Wilderness islands are closed to public access to protect the sensitive wildlife resources. However, portions of Boca Grande, Woman, and the Marquesas Keys are open to wildlife-dependent recreations uses by the public.
These Wilderness islands are characterized by flat topography which, at points, only rises to 6-10 feet above sea level. Climate, here, is characterized as Tropical-Maritime with a mean annual temperature of about 77 degrees F. The Florida Keys experience the highest level of solar radiation in the State of Florida. The southern latitude and maritime influences contribute to minimal seasonal variation. The coldest average monthly temperature, 68.9 degrees F, occurs during January and the warmest mean monthly temperature, 83.8 degrees F, occurs in August. Rainfall is seasonal with wet periods extending from May through October and annual precipitation totals about 39 inches. Common wildlife on the islands includes the state-listed white-crowned pigeon, the endangered Lower Keys marsh rabbit, Key deer, iguana, loggerhead turtle, Atlantic green turtle, Atlantic hawksbill turtle, brown pelican, piping plover, roseate tern, Miami blue butterfly, reddish egret, and great white heron. Common vegetation includes black, white, and red mangrove, slash pines, Gumbo-limbo, Florida butterfly orchid, and yellowheart trees.
