B. PRESENT LEGAL OR OTHER FORMAL STATUS 



1. Federal Status 



a. U.S. Fish and Wildlife Service: 3C (UDSI Fish and 



Wildlife Service 1993); This signifies that the 

 species has "proven to be more abundant or 

 widespread than previously believed and/or .... (is) 

 not subject to any identifiable threat." 



b. U.S. Forest Service: none 



c. Bureau of Land Management: Agastache cusickii is 



included on the BLM list of proposed sensitive 

 species for Montana (USDI Bureau of Land Management 

 1993) . 



2. State: The Montana Natural Heritage Program ranks the 

 species as G3 and SI. In Montana it is "critically 

 imperiled due to extreme rarity (5 or fewer occurrences)" 

 (Heidel 1994). Globally, it is somewhat less vulnerable 

 to extinction. 



C. GEOGRAPHICAL DISTRIBUTION 



1. Species range: scattered in the mountains of southeastern 

 Oregon, north and central Nevada, central Idaho 

 (Cronquist et al . 1984), and southwestern Montana. The 

 species is not included in Dorn (1984). 



2. Montana distribution: Tendoy Mountains, Beaverhead 

 County. 



3. Occurrences in the Tendoy Mountains: Prior to 1994, 

 Agastache cusickii was known in Montana from a single 

 population on BLM land in the southwestern Tendoys on a 

 slope above Big Sheep Creek (001). Three additional 

 populations were found during this project on the 

 Beaverhead National Forest in Kelmbeck (004), Patterson 

 (002), and Williamson-Wood (003) canyons. Element 

 Occurrence Records and maps showing precise locations of 

 the populations on the Beaverhead National Forest are 

 included in Appendix D. 



D. HABITAT 



1. Associated vegetation: In the Tendoys, Agastache cusickii 

 grows on open slopes with little vegetation cover. Woody 

 dominants which are present on these slopes, but not 

 generally immediately associated with Agastache cusickii , 

 include limber pine {Pinus flexilis) , Douglas fir 

 (Pseudotsuga menziesii) , mountain mahogany {Cercocarpus
