Non-game Mammals 



Twenty-nine species of mammals were observed in the study area 

 (Table 23). Mink [Huite-la vlion] and yellow-bellied marmots 

 {Hafimota llavlv z.ntnli>] were observed in the region and probably 

 occurred in the study area. One dead hoary bat was found in 

 riparian habitat. Other species of bats undoubtedly were 

 present in the study area. The blacktail prairie dog was 

 listed by Flath (1979b) as a species of special interest or 

 concern. Two small towns were located (Figure 21).

Six small-mammal traplines were run in the study area, one each 

 in grassland, sagebrush, ponderosa pine-juniper, and marsh 

 riparian habitat, and two traplines in boxelder-ash riparian 

 habitat (Figure 16). The marsh riparian habitat consisted of 

 a cattail [Typha], bulrush [SalfLpui] area around a stockpond. 

 Table 24 lists the total trap nights, trapping success, and 

 numbers of each species caught in each habitat. The highest
