The French Creek population (009) is the largest one 

 known in Montana (1,845 plants, 13 subpopulations) . 

 The habitat is in an area of historic and recent mining 

 activity. Because this is a substantial, viable 

 population in mostly native habitat, all future 

 management activities in the area should be assessed, 

 to determine potential impacts on P. lemhiensis . 



Ongoing studies of P. lemhiensis continue to reveal 

 that the species consists of small populations, many of 

 which are vulnerable to management activities. In 

 addition, drastic declines in population size appear to 

 have occurred in several populations occupying natural 

 or semi-natural habitats. These factors indicate that 

 Penstemon lemhiensis should be retained on the U.S. 

 Forest Service Region 1 sensitive species list. 



C. PROPOSALS FOR FUTURE STUDIES: The following 



recommendations are made regarding continuation of 

 field and demographic monitoring studies of P. 

 lemhiensis : 



1. Monitoring of known populations, especially those 

 that appear to have suffered serious declines over 

 the last four years. 



2. Continuation of the demographic monitoring studies 

 in 1990, including rereading the transects 

 established in 1989, and establishing three 

 additional transects within suitable populations. 



3. Field surveys for new populations in suitable 

 potential habitat, as funding and project 

 delimitation allow.
