locality and two near the headwaters of Birch 

 Creek in Lemhi County. All four populations 

 appear to be small according to 1997 survey 

 information. Little survey work has been 

 conducted and the distribution of the plant 

 is largely unknown (R. Moseley, Idaho 

 Conservation Data Center, pers. comm.). 



b. Montana: There are 33 recently verified 

 Carex parryana ssp. Idahoa populations in 

 Montana. During the past ten years extensive 

 field studies have been conducted on public 

 lands in Beaverhead and Silver Bow counties 

 by botanists working for the Montana Natural 

 Heritage Program. These include studies of 

 the Highland Mountains, Tobacco Root 

 Mountains, upper Madison Valley, the Ruby 

 Range, the Tendoy Range and southern 

 Beaverhead County including the Centennial 

 Valley. Lesica conducted field surveys for 

 this species in 1997, visiting public lands 

 in the southern Gravelly Range, the Ruby 

 Range, the southern Pioneer Range, the 

 Highland Range, the Centennial Valley and the 

 Beaverhead Range. Known sites and their
