II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: Populations 

 occur in undisturbed mountain meadows. The only human- 

 caused threats to A. lackschewitzii currently are from 

 trails and their associated maintenance or erosion, and 

 from grazing by sheep and cattle. The full extent of 

 these activities is not known for each population. 

 However, extensive sheep grazing was observed in the 

 Haystack Peak population (007) . Cattle graze south of 

 the population at the outlet to the Campfire Lake 

 Pothole (005) • Pack trails bisect both populations, 

 and some plants occur near trail edges. 



B. MANAGEMENT PRACTICES AND RESPONSE: Aqoseris 

 lackschewitzii populations probably will respond to 

 management actions designed to prevent trampling or 

 other mechanical soil damage in moist to wet meadow 

 sites. These management actions include restricting 

 grazing and routing trails around wet areas to more 

 suitable dry sites. If trails cannot be relocated, 

 trails through wet areas should be built to a high 

 standard to prevent wide, multiple paths from 

 developing as users attempt to avoid muddy conditions. 

 Micro-habitat differences may account for sites with 

 seemingly suitable habitat that currently do not 

 contain populations of A. lackschewitzii . 



C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: 

 All populations should be considered in any habitat 

 alteration projects on U.S. Forest Service lands. 

 Detailed surveys should precede any proposed 

 disturbances in or near populations. Mitigation
