2. Competition 



a. Intraspecific: Individual plants of 

 Lesquerella humilis are usually sparsely 

 distributed and thus, there is probably 

 little competition among them. 



b. Interspecific: Lesquerella humilis 

 grows in open areas with little 

 vegetation cover or shade which suggests 

 that it is largely intolerant of 

 competition from other plants. In a few 

 cases, however, plants were observed 

 growing among small mats of associated 

 vegetation. These situations may arise 

 from the suitability of such microsites 

 for seed germination. 



D. Hybridization 



1. Naturally occurring: None known. 



2. Artificially induced: None known. 



3. Potential in cultivation: Unknown. 



E. Other factors of population ecology: None known. 

 Current land ownership and management responsibility 



A. General nature of ownership: United States 

 Government. 



B. Specific landowners: 



U.S. Department of Agriculture, Forest Service 

 Bitterroot National Forest 

 316 N. Third Street 

 Hamilton, MT 59840 



C. Management responsibility: same as ownership 

 above. 



D. Easements, conservation restrictions, etc.: The 



three sites where Lescfuerella humilis occurs are 

 largely within the Selway-Bitterroot Wilderness 

 Area which provides some protection from 

 disturbance due to resource exploitation. The St. 

 Mary Peak site (001) is within a proposed Special 

 Interest Area (Evenden 1990) . The primary 

 purposes for the SIA "are 1) to provide public
