2. POPULATION SIZE AND CONDITION: Only two or three plants were 

 found at the sites in mile habitat traverses that were greater than or equaling Vi 

 mile. 



3. REPRODUCTIVE BIOLOGY 



a. TYPE OF REPRODUCTION: By seed. 



b. POLLINATION BIOLOGY: Insect-pollinated. 



c. SEED DISPERSAL AND BIOLOGY: Unknown. 



F. POPULATION ECOLOGY 



1. COMPETITION: The fact that heavy invasions of exotic species (such as 

 Kentucky bluegrass) were found above and below the populations at both sites 

 suggests that the species' rarity may be due to the competition resulting from 

 habitat alteration. 



2. HERBIVORY: Unknown. 



3. FIRE: The Ash Creek population is within the area of the 1988 wildfire. 



G. LAND OWNERSHIP (MONTANA): Land ownership affecting the species is 

 unknown, aside from the two District populations. 



H. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



1. THREATS TO CURRENTLY KNOWN POPULATIONS: Salvage 

 logging operations at the Ash Creek site could eliminate the population by 

 surface disturbance or by fiirther exacerbation of weed invasion. 



2. MANAGEMENT PRACTICES AND RESPONSES: Both populations 

 appear to be relicts of once-larger populations, considering of their land use 

 histories. The Ash Creek population has had moderate livestock use and recent 

 fire. The Poker Jim population is in an area providing pasture for lookout pack 

 animals and for more recent livestock grazing. 



3. RECOMMENDATIONS FOR MAINTAINING VIABLE 

 POPULATIONS: 



The two known populations are small and may have low viability. While it 

 would be appropriate to address potential impacts of any proposed changes in 

 the areas of these populations, focus should instead be placed upon further
