|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Facilitator/Compiler(s):||Green, C., Sharp, D. & Garcia Moreno, J.|
Listed as Least Concern in view of the large extent of occurrence, large number of sub-populations and localities, large population size and use of a wide range of habitats.
|Previously published Red List assessments:||
|Range Description:||This species' range includes most of eastern USA and the northern shore of Lake Erie in Canada (Conant and Collins 1991). It is absent from northern New England and the Florida peninsula.|
Native:Canada (Ontario); United States (Alabama, Arkansas, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Vermont, Virginia, West Virginia)

|Population:||The population is widespread, generally common and relatively stable, with local declines.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It can be found in wooded areas, river valleys, floodplains and agricultural areas, usually in areas with deep friable soils. It burrows underground or hides under rocks, plants, or other cover when inactive. Eggs and larvae develop in shallow water in marshes, rain pools, ponds, lakes, reservoirs, flooded areas, and other bodies of water lacking a strong current.|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||Generally, there are no major threats to this species.|
This species occurs in many protected areas in the United States. The majority of Fowler’s Toad habitat in the Rondeau Provincial Park and Long Point areas is located within a Provincial Park or National Wildlife Area where there is no direct threat from industrial or urban development (COSEWIC 2010). No conservation measures are needed.
Research is needed for population size and trends.
