Mule deer observations per hour of aerial survev ranged from 15.9 



In summer of I98O to 56.9 In fall (Table 139). This suggests a 



higher deer population than In the Blrney or Klrby areas. Most of 



these deer were concentrated In the southern half of the study 



area. The population status, movements, and observability of mule der . 



is being studied by the Pish and Wildlife Service (Biggin and PhllllpL^ 



1979). 



Mule deer population structure was determined during October and 

 November. Pawn production was fair at 8I.I fawns/100 does and 

 55.8 fawns/100 adults In October (Table l40). The low fawn
