The only other subtype to receive more than mininal usage was 

 the agricultural sagebrush/grassland subtype in the summer of 

 1980, where 9 percent of the antelope were observed.

Activity: Antelope are more apt to run during aerial observation 

 surveys than are mule deer. During the summer surveys, the highest 

 percentage of running antelope were observed feeding in the spring 

 months. More antelope were observed standing, 51 percent, in the 

 winter time than in any other season. 



Use of topography : Antelope were most often observed on dissected 

 mid-slope areas (Table 13) in all seasons. The percentage observed 

 ranged from 74 in the summer of 1980 to 97 in the fall of 1979. 

 Alluvium/terraces received use in every season except spring 1979 

 reaching its highest level, 21 percent, in summer 1980. Mesa-butte 

 tops were slightly used every season except fall 1979. Mesa-butte 

 steep sides and flood plains were seldom used.
