The Okefenokee Swamp, named a National Wildlife Refuge by President Franklin Delano Roosevelt in 1937, is the United States' largest intact wetland. Albert Hazen Wright's survey of the life histories of the frogs found in the Okefenokee at the beginning of the twentieth century is a classic of natural history, and has been long out of print. He offers an extensive general discussion of the Okefenokee and its frogs, including habitats, range, coloration, measurements, vocalization, mating, structural differences, ovulation, life periods, tadpoles, growth rates, food, and predators. The book's species accounts give clear and extensive details about the species found in Georgia, still applicable today to frogs throughout the East Coast of the United States.
