SPECIES DELETED FROM APPENDIX 2 



Antennaria pulcherrima - The habitat that this species requires 

 calcareous fens and carrs is not known from the Elkhorn or 

 Big Belt Mountains. Also this species is no longer being 

 tracked by the Montana Natural Heritage Program as the 

 species is questionable taxonomically . 



Arenaria kinqii - The report of this species from the Big Belt 

 Mountains may be based on a misidentif ied specimen. All 

 other Montana collections are from Beaverhead County. This 

 species probably does not occur in either the Big Belt of 

 Elkhorn Mountains. 



Astragalus molybdenus - The habitat that this species occupies 

 alpine calcareous scree is not available in the Elkhorn or 

 Big Belt Mountains. 



Carex livida - This species occurs only in peatlands, 



particularly calcareous ones. 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. 



Carex paupercula - This species is found in peatlands in the 

 montane 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. 



Castilleja exilis - This species is known from alkaline meadows 

 and marshes, primarily at lower elevations. This type of 

 habitat is not known from the Elkhorn or Big Belt Mountains. 



Claytonia lanceolata var. f lava - This taxon will be submerged 



within another more widespread and common species, and thus 

 will no longer be of concern. 



Cypripedium passerinum - This species grows in peaty soils in the 

 ecotone between wet mossy coniferous forests and wetlands or 

 streams. The Elkhorn and Big Belt Mountains do not support 

 this type of habitat, and are outside the known range of 

 this species. 



Drosera linearis - This species requires sphagnum bogs. 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. 



Eriophorum viridicarinatum - This species is found in Carex 



dominated peatlands and cold sphagnum bogs in the foothill
