ssp. idahoa is also placed in the Category 3C with no apparent 

 documentation; reconsideration may be warranted. 



Fifteen more species should be dropped from any further 

 BLM consideration as well as active state tracking, though 

 some of them represent limited distribution taxa of 

 biogeographic interest and will be treated as such (See Table 

 3, below). They have been found to be more widespread than 

 previously known, relatively unaffected by unnatural 

 disturbance, or represented in a number of sites which are 

 relatively secure at present. 



Table 3. Species recommended for deleting from BLM 

 sensitive species consideration

Arenaria kingii 



Astragalus argophyllus 



Astragalus leptaleus 



Astragalus lentiginosus 



Cirsium subniveum 



Erigeron gracilis 



Eriogonum ovalifolium var . nevadense 



Gentiana aquatica 



Mimulus suksdorfii 



Pediocactus simpsonii 



Senecio debilis 



Sphaeromeria capitata 



Stanleya viridiflora 



Some sensitive species management concerns may be addressed in 

 the course of habitat management. Conservation biologists 

 generally agree that protecting biological diversity often 

 most efficiently done at the level of communities or 

 landscapes (Noss 1987, Franklin 1993). Focusing on critical 

 plant communities accomodates sensitive plant protection by 

 preserving potential as well as current habitat. It also 

 promotes protection of less conspicuous associate species 

 like insects. The fourteen species identified for 

 consideration as sensitive are found in one of four habitats 

 (Table 4; next page).
