Geographic Range

American toads, Bufo americanus, are only native to the Nearctic region. They are found throughout large portions of North America, from northern Chihuahua in Mexico, northward to James Bay in Canada and eastward from the Imperial Valley of California and the Columbia River Valley in Washington and Oregon to the Atlantic coast from Florida to southern Quebec. They are generally not present in the most southern states or, if they are, only in the northern part. These toads have an immense ability to adapt to their surroundings as long as there is a source of semi-permanent water for them to use in the breeding season. This quality has allowed them to successfully colonize suburban and agricultural areas. (Dickerson, 1906; Oliver, 1955)

Biogeographic Regions:
nearctic (native ).

Habitat

American toads require a semi-permanent freshwater pond or pool for their early development. They also require dense patches of vegetation, for cover and hunting grounds. Given these two things and a supply of insects for food, American toads can live almost everywhere, ranging from forests to backyards. They are common in gardens and agricultural fields. During daylight hours they seek cover beneath porches, under boardwalks, flat stones, boards, logs, wood piles, or other cover. When cold weather comes, these toads dig backwards into their summer homes or may choose another site in which to hibernate. (Le Clere, 2000; Lerner, June 13 1998; Matson, 2002; Rakestraw, 1998)
