Cirsium longistylum G3QS3 



This species was collected during this study in both the 

 Elkhorn and Big Belt Mountains. It is known from meadows, 

 slopes, and roadsides at moderate elevations (4680-8040') in 

 the mountains. Flowering begins in late June and can 

 continue to frost. Seed development starts in late August. 



Cypripedium calceolus G5T3S3 Sensitive 



var. parvif lorum 



This species might possibly be found in the Big Belt and 

 Elkhorn Mountains on organic soils in moist coniferous 

 forests in seepage areas and moist ecotones between 

 peatlands and upland forest at elevations of 3000-6200'. 

 Flowering occurs in May to June. A historic occurrence 

 north of Belgrade has never been relocated. The confidence 

 level of the habitat profile is high and that of the species 

 occurrence is low. 



Delphinium andersonii G5S1 Watch 



This species was collected for the first time in the Big 

 Belt Mountains during the course of this study. Previously 

 it was known from sagebrush valleys and hills in open 

 forests at around 4120' elevation, but in the Big Belt 

 Mountains, the species was found on a talus slope at around 

 5000'. It flowers during May and June. The habitat profile 

 may need more refinement. 



Draba densifolia G5S2 



This species might possibly occur in the Elkhorn and Big 

 Belt Mountains. It is found in open gravelly soil of rocky 

 slopes and exposed ridges in the montane to alpine zones at 

 elevations of 5600-8800'. Flowering occurs May through June 

 depending on elevation. The confidence level of the habitat 

 profile and of the species occurrence is high. 



Epipactis qigantea G4S2 Sensitive 



This species could occur in the Big Belt and Elkhorn 

 Mountains on stable intact groundwater discharge zones 

 located along streambanks, lake margins, edges of peatlands, 

 and around springs and seepage areas, often near thermal 

 waters at elevations of 2900-5800'. Flowering occurs June 

 through August, The confidence level of the habitat profile 

 is high and of the species occurrence is low. 



Eriqeron f laqellaris G5S1 



This species might be found in the Big Belt Mountains on 

 open soil in meadows and open forests in montane zone at 

 around 5000' elevation. Flowering occurs in late June 

 through August. The confidence level of the habitat profile 

 and of the species occurrence is low.
