. Montana amphibian and reptile status assessment, literature review, and conservation plan. Amphibians; Reptiles; Indicators (Biology); Habitat (Ecology); Wildlife conservation. Woodhouse's Toad (Bufo woodhousii) Up-to-date distribution and status information can be found on the Montana Natural Heritage Program's TRACKER website at Distribution/Taxonomy The systematics of the Woodhouse's toad species complex have a long history, but most authors now seem to agree that allozyme and call differentiation studies support evidence for the existence of two subspecies that range from southern Texas to northern Montana and North Dakota, across the desert southwest to northern Utah, and as isolated populations in Idaho, Washington and California (Stebbins 2003; Conant and Collins 1998; Gergus 1994 as cited in Sullivan et al. 1996; Sullivan et al. 1996). Across this range they have been reported at elevations up to 2,440 M (8,000 ft) (Hammerson 1999). Only the Woodhouse's toad, Bufo w. woodhousii, is present in Montana and they have been documented across the plains east of Livingston and Fort Benton and south of the Milk and Missour Rivers. Maximum Elevation 1,326 m (4,350 ft) in Rosebud County (FWP Prairie Fish Survey Crew, MTNHP 2007). Identification Eggs: Laid in long single or double strings containing up to, and possibly more than, 28,493 eggs (Smith 1934; Krupa 1995). Each ovum is black above, gray below, and is loose within the outer jelly string (Smith 1934). Ovum diameters are to mm, but total egg diameters, including the outer jelly string are approximately mm (Smith 1934). Larvae: Body and tail musculature is black to dark brown with gold flecking dorsally and laterally and 217.
