1. Review of past management and land use 

 experiences. 



a. This taxon: As discussed in I.8.C.I., the 

 flowering stems of P. lemhiensis are 

 vulnerable to browsing, probably by native 

 ungulates and cattle. This undoubtedly 

 reduces the amount of fruit and seed set. 

 In time, this would result in declining 

 population sizes if the mortality of 

 established plants exceeded the rate of 

 establishment of new individuals. A 

 portion of the habitat in the Big Hole 

 National Battlefield was burned by 

 prescription, but the effects on P. 

 lemhiensis have not yet been determined.
