Range Description

This species is endemic to North America, occurring widely in the prairies of the United States, extending into southern Canada. Its range extends from southern Manitoba, Minnesota, and northwestern Wisconsin south through the eastern Dakotas, Iowa, eastern Nebraska, Kansas and adjacent northwestern Missouri (Figg 1993), Oklahoma, and western Arkansas to coastal Texas and northwestern Louisiana (Conant and Collins 1991). Populations at the northern end of the range in southwestern Manitoba apparently are separated from the closest occurrences in Minnesota and North Dakota by 193 km and 280 km, respectively (Bredin, 1989 COSEWIC report). Toal and Reiserer (1992, Herpetoogical Review 23: 89) reported subspecies obtusirostris from southwestern Missouri.
