observed. Thus, a population could be lost in 

 grazed areas, since no reliable seed bank is 

 available. Only detailed monitoring will reveal 

 the extent of population loss occurring in those 

 areas which are grazed extensively. 



2. RECREATION: Two populations of M. primuloides are 

 potentially threatened by recreational activities. 

 The population at Lost Trail Bog (004) occurs 

 along the edge of a sphagnum bog that is adjacent 

 to the parking lot at Lost Trail Pass Ski Area. 



It is not known if snow-plowing affects this site. 

 Increased snowpack would reduce the length of the 

 growing season. This population was not relocated 

 in either 1989 or 1990. 



The population in the meadow at Odell Creek (007) 

 is bisected by a trail, and extensive off-trail 

 use by ORVs has impacted portions of the meadow 

 (Cedron Jones, pers. obs.). 



3. TIMBER HARVESTING: Timber harvesting could 

 potentially threaten populations if roads, or 

 other activities associated with the harvest 

 extend into the open meadow habitat occupied by M. 

 primuloides . 



B. MANAGEMENT PRACTICES AND RESPONSE: None known. 



C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: 



Evaluations of the status of several populations need 

 to be made (as listed below) before any management 

 recommendations can be made for this species. 



D. RECOMMENDATIONS FOR FURTHER ASSESSMENT: It is 



recommended that Lost Trail Bog (004) be surveyed for 

 M. primuloides . evaluating the quality of the bog and 

 noting any effect that recreation area might be having 

 on the site. The population at this site has not been 

 relocated since 1985. The current status of M. 

 primuloides at Odell Lake (005) should be evaluated 

 through a survey of the area. Finally, a survey of the 

 two potential Twin Lakes (001) locations should be 

 completed. 



E. SUMMARY: The primrose monkey-flower ( Mimulus 

 primuloides ) is a small member of the Figwort Family
