1. Review of past management and land use 

 experience 



a. Lesquerella humilis: Recreational use 

 probably is currently having an impact 

 on L. humilis at the St. Mary Peak site 

 (001) . Trail #116 traverses the south- 

 facing slope of St. Mary Peak through 

 the southeastern portion of the 

 population and then ascends to the 

 summit, in a series of switchbacks, 

 along the northeastern edge of the 

 population. However, once the trail 

 reaches an elevation of 2685 m (8800 

 ft.), which is the lowermost limit of 

 the L. humilis population, some off- 

 trail hiking directly to the summit is 

 occurring. This use is possibly leading 

 to impacts on the main portion of the 

 population. 



The East St. Joseph (002) and St. Joseph 

 Peak (003) sites are not currently 

 accessible via maintained trails. 

 However, some recreational use 

 undoubtedly occurs in these areas, which 

 might lead to minor impacts on the 

 populations. Other resource management 

 impacts are not known at this time.

Lesquerella humilis is included on the U.S. 

 Forest Service list of sensitive plants for 

 Region 1 (Reel et al. 1989) . As such, it
