ssp. idahoa is compatible with light to 

 moderate livestock grazing. 



In summary, Carex parry ana ssp. idahoa has a 

 small geographic range and occurs in a 

 narrowly defined habitat that is threatened 

 by livestock overgrazing throughout this 

 range. However, C. parryana ssp. idahoa is 

 common in the center of its range and is 

 likely compatible with moderate livestock 

 grazing. Thus, Carex parryana ssp. idahoa 

 should not be considered for listing as a 

 threatened or endangered species at this time 

 and should remain as 3C until it can be shown 

 to be declining or that significant portions 

 of its habitat are being overgrazed. A final 

 recommendation awaits findings in the Idaho 

 portion of its range. 



b. U.S. Bureau of Land Management: Carex 

 parryana ssp. idahoa occurs on public land 

 administered by BLM. It has a narrow 

 geographic range and occurs in a habitat that 

 is sensitive to current land management 

 practices (livestock grazing) . There is 

 evidence that heavy grazing is detrimental to 

 the plant, and some BLM sites (e.g. , Basin 

 Creek) experience intense grazing pressure. 

 Carex parryana ssp. idahoa should remain on 

 the BLM sensitive list until it can be shown 

 that all or most populations are experiencing 

 only light to moderate livestock grazing and 

 that monitored populations are stable. 



c. U.S. Forest Service: Carex parryana ssp. 

 idahoa occurs on land administered by the 

 U.S. Forest Service. It has a narrow 

 geographic range and occurs in a habitat that 

 is sensitive to current land management 

 practices (livestock grazing) , and there is 

 evidence that heavy grazing is detrimental to 

 the plant. Carex parryana ssp. idahoa should 

 continue to have sensitive status. 



d. State of Montana: There are 32 recently 

 verified sites for Carex parryana ssp. idahoa 

 in Montana, and it is likely that many more 

 occur on private land. However, many 

 populations are small, and the habitat is 

 threatened throughout its range. Thus the 

 status of S2 is still warranted.
