. Distribution of mammals in Colorado. Mammals. 1972 ARMSTRONG: COLORADAN MAMMALS 341. Fig. 125. Mammalian distributional areas of Colorado. Colorado Plateau Faunal Area Grand Valley Faunal District Dolores-San Juan Faunal District The above distributional areas relate in a general way with comparable mammalian faunal divisions in Utah (Durrant, 1952:480), Kansas (Cockrum, 1952:15), Nebraska (Jones, 1964:46), and Wyoming (Long, 1965:725). Correspondence between areas in Colorado and those in adjacent states is sufficiently close that no synonymy is considered neces- sary. Comment is in order, however, on units recognized in adjacent states but not in Colo- rado. Durrant (1952:480) mapped seven dis- tributional units along the eastern boundary of Utah. The unit herein called the Wyo- ming Basin Faunal Area corresponds to three units in Utah. The Uinta Mountain Province (of Durrant) might prove recognizable in Colorado west of the Green River with fur- ther knowledge of mammals of that area. No other subdivision in northwestern Colo- rado is indicated. The Uinta Mountains sep- arate distinctive faunal units in northeastern Utah, but there is no comparable barrier to distribution in northwestern Colorado. The area of the Tavaputs Plateau in east- ern Utah was considered by Durrant to repre- sent a subcenter of the Northern Great Plains Faunal Area. The Roan Plateau in western Colorado is, however, considered by me as a westward extension of the Rocky Mountain Faunal Area. There is a gradual attrition westward of highland species from the White River Plateau to the Roan and Tavaputs plateaus. The most obvious ecologic break.
