and montane zones. As there is little such habitat in the 

 Elkhorn or Big Belt Mountains and some of that was searched, 

 it is unlikely that this species occurs in the study area. 



Mimulus primuloides - This species grows around seeps and in 



peatlands in open wet meadows in the montane to subalpine 

 zone. As there is little such habitat in the Elkhorn or Big 

 Belt Mountains and some of that was searched, it is unlikely 

 that this species occurs in the study area. 



Orchis rotundifolia - This species occurs on organic soils with 

 good drainage, often on limestone, in wet mossy coniferous 

 forest edges near peatlands and streams. This habitat type 

 is unknown from the Elkhorn or Big Belt Mountains. 



Oxytropis podocarpa - This species grows on alpine limestone 

 habitat, which is absent or scarce in the study area. 



Ranunculus jovis - This species is found in sagebrush or open 

 areas in spruce-fir parklands in the alpine zone. The 

 Elkhorn and Big Belt Mountains do contain this type of 

 habitat, and are outside the known range of this species. 



Sausserea densa - This species grows on open calcareous talus and 

 loose scree in the alpine zone. This type of habitat is not 

 known from the Elkhorn or Big Belt Mountains which are 

 outside the known range of this species. 



Sausserea weberi - This species is found in moist meadows and 



gentle sparsely vegetated slopes in the alpine zone. This 



type of habitat is not known from the Elkhorn or Big Belt 

 Mountains. 



Saxifraga tempestiva - This species occurs on vernally moist open 

 soil in meadows, rock edges and depressions which retain 

 snow in the krummholz and alpine zones. There is not 

 habitat of this sort in the Elkhorn or Big Belt Mountains. 



Scirpus subterminalis - This species requires quiet fresh water 

 of shallow lakes and ponds in the valley, foothills, and 

 montane zone. As there is little of this habitat in the 

 Elkhorn and Big Belt Mountains, there is only a remote 

 chance of this species occurring there. 



Selaqinella watsonii - This species occupies sheltered outcrop 



microhabitats at high alpine elevations. There is little of 

 this habitat in the Elkhorn and Big Belt Mountains. 



Senecio debilis - This species grows in moist alkaline meadows in 

 the valley and foothills zone. Habitat of the type is not 

 known from the Elkhorn or Big Belt Mountains.
