b. Related taxa: Unknown. 



c. Other ecologically similar taxa: Not 

 reviewed. 



2. Performance under changed conditions: Although 

 P. lemhiensis does have the ability to occupy 

 disturbed habitats, the plants in these 

 situations are not likely to represent long- 

 term subpopulations. Road maintenance and weed 

 control activities are likely to continually 

 remove plants in these areas. The long-term 

 effects of browsing are currently unknown. 



3. Current management policies and actions: 

 Penstemon lemhiensis is included on the U.S. 

 Forest Service list of sensitive plant species 

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

 receives protection under U.S. Forest Service 

 management policies. All of the federal 

 agencies managing lands supporting populations 

 are aware of the presence and locations of P. 

 lemhiensis . 



4. Future land use: Most of the habitats occupied 

 by P. lemhiensis in Montana are used for 

 livestock grazing, and this land use is 

 expected to continue. Three sites containing 

 large populations are in areas of past and 

 potential future mining activity: French Creek 

 (009), Quartz Hill Gulch (010), and Echo Gulch 

 (Oil) . At French Creek, numerous mines have 

 been actively worked in the past, and renewed 

 gold mining has recently been proposed (K. 

 Scow, pers. conn.). At Echo Gulch, mining test 

 pits were observed near the north subpopulation 

 in 1986 (J.S. Shelly, pers. obs.). 



B. Cultivation. 



1. Controlled propagation techniques: None known; 

 seed germination trials have been unsuccessful 

 (see I . 7 . D. 4 .e. ) . 



2. Ease of transplanting: Unknown. 



3. Pertinent horticultural knowledge: Not 

 reviewed. 



4. Status and location of presently cultivated 

 material: No cultivated material known.
