Great Plains Toad (Bufo cognatus) Up-to-date distribution and status information can be found on the Montana Natural Heritage Program's TRACKER website at Distribution/Taxonomy The Great Plains toad is recognized as a distinct species that ranges across the Great Plains from central Mexico to southeastern Alberta and in the desert southwest as far west as eastern California and as far north as southern Utah at elevations up to 2,440 M (8,000 ft) (Stebbins 2003; Goebel 1996). In Montana they have been sparsely documented across the plains east of Shelby, Great Falls, Lewiston, and Billings. Maximum Elevation 1,300 m (4,265 ft) km southeast of Wallop Butte in southwest Powder River County (Chris Hays and David Herasimtschuk; MTNHP 2008). Identification Eggs: Laid communally in single or more rarely double strings containing 1,342 to 45,054 eggs (Bragg 1937a: Krupa 1994). Each ovum is black above, shaded progressively lighter to white below, and surrounded by two jelly layers, including the outer jelly layer that composes the string (Bragg 1937a). Ovum diameters are approximately mm, but total egg diameters, including the two jelly layers are approximately mm; jelly string widths between eggs are approximately mm (Bragg 1937a). Larvae: Mottled brown and gray dorsally and with a light greenish-yellow and reddish iridescence ventrally (Bragg 1936). The dorsal tail fin is dendritically pigmented and highly arched while 208.
