Florida Keys National Wildlife Refuges

Big Pine Key, Florida


The National Wildlife Refuges of the Florida Keys, consisting of a diversity of habitats ranging from open ocean to pine woods, support a wide variety of mammals, reptiles and amphibians. Due to the keys tropical climate, some of these animals are unique to the area and found nowhere else in the United States. The isolation of the keys from the mainland has also resulted in common Florida species evolving into separate forms. The close proximity of major travel and trade ports such as Miami and Key West has spurred the introduction of exotic creatures from the Caribbean and South America. These established exotics, along with the notable native species provide an excellent opportunity to observe a fascinating array of wildlife in the Lower Florida Keys.
