REVISED LIST OF TARGETED SENSITIVE PLANTS (USES REGION 1) 



AND PLANTS OF SPECIAL CONCERN (MTNHP) 



WITHIN THE ELKHORN AND BIG BELT MOUNTAINS 



OF THE HELENA NATIONAL FOREST 



SPECIES MTNHP USPS USFWS 



Adoxa moschatellina G5S1 Sensitive 



This species possibly occurs in the Elkhorn Mountains in 

 moist, mossy places (such as slopes) in woods and rock 

 crevices at elevations of 4400-5400'. Flowering and 

 fruiting run from June through August. The confidence 

 level' of the species occurrence and the habitat profile are 

 low. 



Aqroseris lackschewitzii G3S3 Sensitive 



This species could occur in the Elkhorn and Big Belt 

 Mountains in moist-wet meadows or subalpine wet meadows 

 where the soil is saturated throughout growing season. The 

 species has been collected at 6150-9500' elevation. It 

 flowers from July to early August, and fruits in late 

 August. The confidence level of the habitat profile is 

 high, and that of the species occurrence is low. 



Aquileqia brevistyla G5S1 Sensitive 



This species might grow in the Big Belt Mountains in open 

 woods and streambanks at mid-elevations (5000-6000') in the 

 mountains. Flowering begins in June and wanes in early 

 July. The confidence level of the habitat profile is high, 

 and that of the species occurrence is medium. 



'The confidence level of the species occurrence and the 

 habitat profile refer to the probability either that the species 

 might occur in the area or that the habitat profile includes all 

 habitat types which the species occupies. The rankings are low 

 (unlikely that the species occurs in the area or that the habitat 

 profile includes all habitat types which the species occupies) , 

 medium (a 50/50 chance that the species occurs in the area or 

 that the habitat profile includes all habitat types which the 

 species occupies) , or high (highly likely that the species occurs 

 in the area or that the habitat profile includes all habitat 

 types which the species occupies) . Information for the rankings 

 was drawn from knowledgeable individuals, the Montana Natural 

 Heritage Program database, and the literature.
