|Scientific Name:||Spea intermontana|
|Species Authority:||(Cope, 1883)|
|Taxonomic Notes:||Garcia-Paris et al. (2003) used mtDNA to examine the phylogentic relationships of Pelobatoidea and found that the family Pelobatidae, as previously defined, is not monophyletic (Pelobates is sister to Megophryidae, not to Spea/Scaphiopus). They separated the Pelobatidae into two families: Eurasian spadefoot toads (Pelobates), which retain the name Pelobatidae; and North American spadefoot toads (Scaphiopus, Spea), which make up the revived family Scaphiopodidae.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species can be in Southern British Columbia, Canada (Cannings 1999) southward in the USA through central and eastern Washington and Oregon, southern Idaho, eastern California, Nevada, Utah, Wyoming, and northwestern Colorado to northwestern Arizona (Hall 1998). It can be found from the edge of Cascade-Sierra axis east to the Rockies. It is found at elevations of about 850m asl (Stebbins 1985).|

|Population:||It is widespread and locally abundant. Range size and population levels are relatively stable.|
|Habitat and Ecology:||This species is found mainly in sagebrush flats, semi-desert shrublands, pinyon-juniper woodland. Digs its own burrow in loose soil or uses those of small mammals. Breeds in temporary or permanent water, including rain pools, pools in intermittent streams, and flooded areas along streams. Eggs are attached to vegetation in water or placed on bottom of pool.|
|Major Threat(s):||Most of its habitat is not subject to incompatible uses or major threats.|
|Conservation Actions:||No conservation measures are needed. It occurs in many protected areas.|
