Asplenium trichomanes G5SH Sensitive 



Not collected in Montana since 1895, this species might be 

 found in the Gates of the Mountains Wilderness Area on moist 

 sites on cliffs and crevices in rocky talus at mid-elevation 

 in the mountains. The fronds mature in July. The 

 confidence level of the habitat profile is medium, and that 

 of the species occurrence is low. 



Astragalus convallarius G5T5S2 

 var . convallarius 



This species was collected in the northern part of the Big 

 Belt Mountains during the course of this study, and was also 

 found just outside the Helena National Forest boundary of 

 the Elkhorn Mountains. While it may possibly extend into 

 the Elkhorn Mountains, the most promising potential habitat 

 is at lower elevations outside of administrative boundaries. 

 It occurs in grasslands and sagebrush in the valleys and 

 foothills at elevations of 3880 to 4400' in the Helena 

 National Forest vicinity and at 8100' in Beaverhead County. 

 Flowering begins in May to early June depending on 

 elevation. 



Botrychium paradoxum GlSl Sensitive C2 



This species could possibly be found in the Elkhorn and Big 

 Belt Mountains in grasslands and meadows (moist shrubby ones 

 often near lakes) in the foothills and montane zones at 

 4000-8200' elevation. The fronds mature in July. The 

 confidence level of the habitat profile and of the species 

 occurrence is low. 



Carex multicostata G5S1 Watch 



This species possibly occurs in the Elkhorn and Big Belt 

 Mountains in meadows, woods, and on open slopes. It is 

 found at moderate elevations, but occasionally ascends above 

 timberline (6000-11000' elevation) . Flowering and fruiting 

 are in July. The confidence level of the habitat profile 

 and of the species occurrence is medium. 



Carex vallicola G5S2 



This species has been collected once in the Big Belt 

 Mountains, without precise locality information, and might 

 possibly occur in the Elkhorn Mountains. It grows on moist 

 or moderately dry slopes from the foothills to moderate 

 elevations (5760-7080') in mountains, often with sagebrush 

 or aspen. Flowering is in June, and fruiting is in late 

 June through August. The confidence level of the habitat 

 profile is medium and the species occurrence has previously 

 been documented on the Helena National Forest.
