Antelope winter ranges must be considered key habitat and 

 the public lands that make up parts of these winter ranges must 

 be classified as very important keys to these winter ranges. 

 The following is a list of public lands that are antelope winter 

 range under average winter conditions and under severe winter 

 conditions: 



W inter Range - average winter conditions 



State - S 8,9,10,15,16,18,20, T22N, R19E; S 1,4,9,10,11,

W inter Range - severe winter conditions 



State - S 15,16, T21N, R16E; S 34, T23N, R16E; 

 S 1,2, T22N, R19E. 



BLM - S 17,22,26, T24N, R17E; S 4,5,7,8,9,17,18, T21N, 

 R15E; S 3,10, T21N, R16E; S 34, T23N, R16E; 

 S 33,34, T23N, R20E; S 6, T22N, R21E; S 17, T21N, 

 R22E; S 14, T25N, R16E. 



CMR* - S 27,28, T22N, R23E; S 18,19,30, T22N, R24E; 

 S 13,21,22,23,24, T2 2N, R2 3E. 



*CMR = Charles M. Russell National Wildlife Range. 



Since the above-mentioned lands are critical to the survival of 

 antelope, the involved land managers should key their land man- 

 agement to protect and enhance this wildlife resource. 



The land use practice most detrimental to antelope on the 

 study area is the destruction of sagebrush. Under no circum- 

 stances should state or federal land managers allow sagebrush 

 eradication on antelope range, especially winter ranges. Over- 

 grazing is another land use practice that must be regulated on 

 public lands, as it has a negative impact on antelope. Since 

 antelope are a migratory big game animal, public land managers 

 should avoid the construction of antelope-tight fences which 

 prevent antelope from moving throughout their home range. This 

 can be extremely important during severe winters when antelope 

 may need to migrate longer distances to suitable wintering areas.
