Table 10. Antelope harvest (Districts 470 and 610) 



Eastern Segment 



Antelope are primarily distributed throughout the nonbreaks 

 portion of the study area; however, data gathered during the past 

 two severe winters revealed that antelope will use breaks habi- 

 tat for wintering when a winter reaches such severe proportions 

 that snow depths bury the sagebrush on their traditional winter 

 ranges. Antelope distribution was accomplished by obtaining 

 year-round observations (Constan 76, 77, 78 and Appendix Table 

 3). 



Summer aerial surveys were made within the Hunting District 

 480 portion of the study area on July 25, 1978 and in Hunting 

 District 471, north of State Highway 81 on July 31, 1978. Obser- 

 vations on these flights were plotted in Figure 16. A total of 

 495 antelope was observed and classified as 239 does, 189 fawns 

 and 67 bucks in Hunting District 4 80. This total was 32 percent 

 more than the 376 antelope censused in the same area in 1977. 

 The fawn/doe ratio of 79 fawns per 100 does in 1978 was higher 

 than the ratio of 66/100 in 1977. A total of 235 antelope was 

 observed and classified in Hunting District 471. The 119 does, 

 93 fawns and 23 bucks resulted in a 78 fawns per 100 does ratio. 



An important part of this study was the determination of 

 antelope winter range used under average winter conditions and 

 winter range used under severe winter conditions. These winter 

 ranges were determined and plotted in Figure 17.
