measures should be developed to reduce or eliminate the 

 impacts of management activities. 



The effects of grazing on A. lackschewitzii population 

 dynamics are unknown. An excellent area to place long- 

 term monitoring plots and exclosures would be at the 

 Haystack Peak population (007) . This area could 

 provide information about population responses to 

 grazing activity and trail impacts. 



RECOMMENDATIONS FOR FURTHER ASSESSMENT: Much potential 

 habitat remains to be surveyed throughout all 

 southwestern Montana forests. Surveys should include 

 moist to wet meadows along stream courses and 

 surrounding subalpine to alpine lakes, in the mountains 

 of the Anaconda Range, Tobacco Root Mountains, Little 

 Belt Mountains, Absaroka-Beartooth Mountains, Gravelly 

 Range, and portions of the Crazy Mountains not 

 surveyed. 



SUMMARY: Aqoseris lackschewitzii is a regional endemic 

 with very limited distribution in eight Montana 

 counties and two Idaho counties. Field surveys by 

 Montana Natural Heritage Program in 1990 located an 

 additional subpopulation at Haystack Peak (007) and an 

 additional population at Campfire Lake Pothole (005) on 

 the Gallatin National Forest. Five additional 

 populations were located on the Lewis & Clark National 

 Forest in 1990 by Dana Field. It is included on the 

 Watch List for Region 1 of the U.S. Forest Service. 

 Low proportions of flowering plants, lack of 

 information on the population dynamics and on the 

 species' response to grazing pressure, indicate a need 

 to monitor the populations. In the absence of 

 information on species' response, these sites v/ill need 

 to be carefully assessed when planning land use 

 activities that might affect A. lackschewitzii 

 populations .
