Threats: The precise location of the Antennaria densif olia 

 population at Goat Flat is not known but it is likely that the 

 only threat would be from trampling or trail development. Also, 

 the size and areal extent of the population is unknown which 

 makes it impossible to gauge the results of possible impacts. 



Recommendations for Maintaining Viable Populations: Management 

 plans should take the occurrence of this species fully into 

 account and prevent disturbance to the sites. To prevent 

 inadvertent impacts, detailed information on the location of 

 populations in the Goat Flat Proposed Research Natural Area 

 should be made known to all personnel involved in planning 

 activities in the area. Additional surveys of talus slopes in the 

 Goat Flat area should be done to fully delineate the extent and 

 size of populations in the Goat Flat Proposed Research Natural 

 Area. 



Salix wolf ii var. wolf ii (Wolf's willow) 



Species Information: The genus Salix contains about 300 species, 

 mostly in the Northern Hemisphere (Hitchcock et al. 1955-1969). 

 Thirty-four species are reported for Montana (Dorn 1984). Sal ix 

 wolf ii contains two varieties which are differentiated primarily 

 by whether the capsules are hairy or not. Variety wolf ii has 

 glabrous, or occasionally subglabrous, capsules and occurs mainly 

 in Colorado, Utah and Wyoming, barely entering southwestern 

 Montana and eastern Idaho (Hitchcock et al. 1955-1969). Variety 

 idahoensis has hairy capsules and occurs more in the northern and 

 western parts of the range, although both varieties are sympatric 

 in southwest Montana. 



Present Legal or Other Formal Status: Salix wolf ii var. wolf ii 

 currently has no status under the Endangered Species Act but is 

 on the Sensitive list for Region 1 of the U.S. Forest Service. It 

 is currently ranked by the Montana Natural Heritage Program 

 globally as G4T4 (apparently secure globally although it may be 

 rare at the periphery of its range, >100 occurrences; T refers to 

 the variety) and in Montana as SI (imperiled because of rarity, 

 <5 occurrences) . 



Geographic Distribution: The species as a whole occurs widely 

 from Oregon to Montana and south to Nevada, Utah and Colorado. 

 The variety wolf ii occurs from southwest Montana and eastern 

 Idaho south to Colorado and Utah, and is currently known from 

 four locations in Montana. The other three locations are in 

 southern Madison and Gallatin counties. Thus, the population at 

 the Goat Flat Proposed Research Natural Area is peripheral and 

 the most northeasterly location known for the species. 



Habitat: Salix wolf ii var. wolf ii occurs along streambanks and in 

 wet meadows in the subalpine zone.
