Great White Heron National Wildlife Refuge in Florida is a haven for great white herons, migratory birds and other fascinating wildlife. The refuge consists of almost 200,000 acres of open water and scattered islands, and is known in the Keys as the “backcountry.” The refuge provides critical nesting, feeding and resting areas for hundreds of species of birds and sea turtles. The beaches, mangroves and sparkling blue water are favorites for the visitors who explore this beautiful and fragile place. Photo by U.S. Fish and Wildlife Service.
