Non-game Mammals 



Ten species of mammals were observed in the study area 

 (Table 59). Desert cottontails [Sylvilagu-i audubonll) 

 and yellow-bellied mormots {Uan.mota {)lavive,nt^li ] were 

 observed within ten miles of the study area and probably 

 occurred in the study area. 



Two small-mammal traplines were located in the study area, 

 one in ponderosa pine-juniper habitat and the other in box- 

 elder-ash riparian habitat (Figure 36). Table 60 lists the 

 total trap nights, trapping success, and numbers of each 

 species caught in each habitat. The highest number of species 

 and trapping success were on the trapline in riparian habitat. 

 This trapline was in an area with a heavy infestation of 

 grasshoppers. The grasshoppers cleaned the bait off and tripped 

 manysnap traps, and clogged the pitfall traps. This may have 

 lowered the trapping success.
