Mountains is the more likely location of the two, 

 due to its proximity to a road. Information on 

 this site (001) is included in the element 

 occurrence records p. 26, but it is currently 

 unmappable . 



AREAS SURVEYED BUT SPECIES NOT LOCATED: Lost 

 Trail Bog (004) was surveyed on 18 July 1989 by 

 Andy Kratz (Lolo National Forest) , and again on 9 

 July 1990 by Diane Pavek (Montana Natural Heritage 

 Program. Neither were able to locate any plants, 

 and both suggested that the bog should be 

 resurveyed. Both survey dates were quite early 

 compared to the successful location of other 

 populations by field crews in the last week of 

 July of 1990. It is possible that a survey toward 

 the end of July might reveal the presence of the 

 population. 



E. HABITAT 



1. ASSOCIATED VEGETATION: Populations of M. 

 primuloides occur in open areas at the edges of 

 peatlands and in wet meadows. Species associated 

 with M. primuloides at one or more locations in 

 Montana include: 



Carex interior (inland sedge) 

 Carex spp. (sedge spp.) 

 Drosera anqlica (great sundew) 



Eleocharis pauciflora (few-flowered spike-rush) 

 Gentianopsis simplex (hiker's gentian) 

 Liqusticum tenuifolium (slender-leafed licorice- 

 root) 



Mimulus quttatus (common monkey-flower) 

 Muhlenberqia f iliformis (slender muhly) 

 Saxifraqa arguta (brook saxifrage) 

 Senecio triangularis (arrowleaf groundsel) 

 Viola macloskevi (small white violet) 



This list is probably incomplete, and more 

 inventory would be necessary to give a 

 comprehensive list of associated species. 



2. TOPOGRAPHY: In Montana, populations of Mimulus 

 primuloides are found on level to gently sloping 

 sites, which probably do not much exceed ten 

 percent. The known sites in Montana range from 

 approximately 7,000 ft. (2130 m) to approximately 

 8,500 ft. (2590 m) in elevation. According to
