II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: The potential 

 threats to certain populations of L. klausi i consist of 

 i.) mining and oil/gas exploration activities, ii.) 

 road maintenance/construction, and iii.) grazing. The 

 sites which may be impacted by these activities are 

 reviewed below: 



1. MINING AND OIL/GAS EXPLORATION ACTIVITIES: 

 Several populations in the Big Belt Mountains may 

 potentially be impacted by future mining 

 activities. In particular, gold mining has 

 recently increased in the vicinity of York. Two 

 mine claim posts were observed on the Bull Run 

 Gulch (016) site. The Sweats Gulch (017) site is 

 similar to the Bull Run Gulch site, although no 

 mine claim posts were seen. Other sites on U.S. 

 Forest Service lands which are currently 

 unprotected, and which could possibly be impacted 

 by future mining activities, include:
