Federal agencies recognize species protected under the Endangered 

 Species Act, and the U.S. Fish and Wildlife Service has developed 

 draft Section 7 consultation guidelines for addressing potential 

 impacts (U. S. Fish and Wildlife Service 1995a.) 



c. Review of past status: In addition to the original listing document 



(U.S. Fish and Wildlife Service 1992) and draft Section 7 consultation 

 guidelines (U.S. Fish and Wildlife Service 1995a), the U.S. Fish and 

 Wildlife Service has prepared a draft recovery plan (U.S. Fish and 

 Wildlife Service 1995b). 



2. State. 



Montana. Spiranthes diluvialis was first discovered in Montana in 

 1994, and sent to Dr. Charles Sheviak for determination. He 

 provisionally identified it as Spiranthes diluvialis. It was treated as 

 unconfirmed imtil cytological determination was made by Dr. Sheviak 

 in 1995 (Heidel 1995). It was published as a new addition to the state 

 flora the following year (Heidel 1 996a). 



i. Present designated or proposed legal protection or 



regulation: Spiranthes diluvialis is currently ranked as 

 "globally imperiled" owing to extreme rarity (global rank = 

 G2; generally 20 or fewer occurrences.) In this case, there are 

 app. 90 occurrences rangewide and this rank was last updated 

 by the Utah Natural Heritage Program in 1984. The rank is 

 conditioned by quality, condition, viability and vulnerability of 

 the occurrences, and the prospective aggregation or 

 interconnectedness of these occurrences along rivers into far 

 fewer occurrences. 



It is recognized as an imperiled species of special concern in 

 Montana (state rank =S2), owing to extreme rarity (10 

 occurrences), small occurrence size, lack of protection, and 

 threats. This rank is not a designation, nor does it afford legal 

 protection or regulation. 



ii. Other current formal status 

 recommendations: None. 



iii. Review of past status: NA
