Kirby 



Mule Deer 



Population characteristics : During the studv 1,325 mule deer were 

 observed in the Kirby study area (Table 112). Average group size 

 ranged from 1.9 in summer to 6.6 in winter. Deer followed the 

 annual oattern of large groups during winter and early spring, 

 and small groups during summer when they dispersed and moved to 

 summer range. 



Mule deer observations per hour of aerial survey ranged from 

 7.5 deer/hour in summer to 33.6 deer/hour in winter (Table 113). 

 Many more deer were observed in the western half of the study 

 area than in the eastern half, so these values represent the 

 average of the two greatly different areas. 



Mule deer population structure was determined during October and 

 November (Table ll4). Fawn production was much better than on 

 the Blrney area, with 93.5 fawns per 100 does observed in 

 October, when 85 deer were classified. This population is probably 

 stable or increasing slightly (Swenson 1978a). 



Distribution: Spring distribution is shown in Figure 9^. Deer 

 groups were scattered throughout the study area, but the largest 

 groups were all located in the western half of the study area. 



During summer mule deer were broken into small groups and 

 dispersed throughout the study area (Figure 95). The groups 

 tended to be more numerous in the western half of the study area, 

 which is higher and wetter, with better developed riparian areas 

 and more lush grassy cover than the eastern half. The western 

 half appears to be much better summer range for mule deer than the
