GAME ANIMAL DEPREDATION 



Private landowners in the Robb/Ledford area were concerned with the effects of elk on their ranching 

 operations prior to the acquisition of the WMA. Since that time, some complaints still occur but they 

 are minimal. In addition, the adjacent private land with the greatest potential for game damage 

 complaints is not presently open to public hunting. Antelope and both species of deer use hayfields 

 and haystacks on this private land. 



ZONE OF INFLUENCE 



The WMA has a far reaching zone of influence. Hamlin and Ross (1992) report elk radioed on the 

 WMA are distributed widely throughout the Gravelly Range during the summer. Also, with the 

 winter range providing for mule and whitetail deer and antelope, the WMA has a far reaching 

 influence for these species as well. Game bird species are year around residents of the WMA. 



MINERAL-OIL/GAS 



At present there are no mining, oil or gas activities on the WMA. The majority of the mineral rights 

 and oil and gas leasing rights are under federal government jurisdiction. However, when FWP 

 purchased the property, 51.52% of the pnvate mineral rights were also assigned to FWP. The 

 potential for exploration exists. Requests will be considered as received in compliance with the 

 Montana Environmental Policy Act and cooperatively with the BLM. DNRC land (approximately 

 10,000 acres) associated with the WMA is leased for agricultural purposes only and FWP has no 

 control over minerals. 



LIVESTOCK GRAZING 



Livestock grazing on the WMA is and will continue to be conducted under a rest-rotation grazing 

 system incorporating the principles developed by Hormay (1970). This system involves the grazing 

 of cattle through each pasture on a three year rotation of early use (mid-June to seed ripe mid- 

 August), late use (seed ripe to October), and then complete rest. 



Presently, the status of this grazing system and coordination with adjacent public land managing 

 agencies (USFS, BLM) is not finalized. In 1999 and 2000, FWP will be completing a planning
