vegetation, slope, aspect, parent material, size of population, 

 quality of population, and threats to the population. 

 Photographs (35 mm transparencies) were taken of the species and 

 their habitats. 



We collected voucher specimens of all species of concern 

 when there was adequate material as defined by the Montana Native 

 Plant Society collecting guidelines (MNPS 1993). Specimens will 

 be deposited at the herbarium of the University of Montana 

 (MONTU) . 



Results 



We are aware of 12 species of vascular plants in the Sage Creek 

 area listed as species of special concern by the Montana Natural 

 Heritage Program (Heidel 1995) : 



Astragalus termlnalis 

 Calochortus bruneaunis 

 Carex parryana idahoa 

 Eriogonum caespitosum 

 Halimolobos virgata 

 Primula incana 

 Sphaeralcea munroana 

 Sphaeromeria argentea 

 Thelypodium sagittatum 

 Thlaspi parviflorum 

 Townsendia florifer 

 Townsendia nuttallii 



Three of these. Astragalus termlnalis, Carex parryana idahoa and 

 Sphaeromeria argentea are on the proposed BLM sensitive species 

 list. Descriptions of these 12 species, their range and habitat 

 are presented below.
