II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: 



1. GRAZING: Arabis fecunda does not appear to be 

 preferred by domestic grazers. However, the Jerry 

 Creek population (007), Silver Bow County, and the 

 Birch Creek (004) and Charleys Gulch (001) 

 populations, Ravalli County, have been impacted by 

 the trampling associated with grazing. 



2. MINING: A subpopulation of A. fecunda plants at 

 the intersection of Highway 43 and Quartz Hill 

 Gulch (site = The Mouth of Quartz Hill Gulch 

 (006) , BLM managed land) is threatened by gravel 

 removal from the base of the hill. 



Subpopulations of Upper Quartz Hill Gulch (008) 

 are near areas where mining has occurred in the 

 past. This population could be impacted, should 

 mining activities resume in the future.
