Aa Present or threatened destruction^ modification* 

 or curtailment of habitat or range. 



1. Past threats: Heavy development of the Lolo 

 Hot Springs area for recreational use has 

 evidently led to the extirpation of the 

 taxon from the immediate vicinity, as 

 discussed above. Other past threats to the 

 currently known sites were not evident in 

 their immediate habitats, but the surrounding 

 slopes have been heavily impacted by 

 selective and clear-cut timber harvesting. 

 There is a logging road through a portion of 

 the meadow at the Granite Creek North site, 

 but the Tr i setum or thochaetum site is about 

 300 yds. away from it. 



2. Existing threats: There is a warm spring on 

 the west side of Granite Creek adjacent to 

 the Granite Creek South site. The spring, 

 and the surrounding meadow, are heavily used 

 for camping by hunters and other 



recreat ionists . As a result, the vegetation 

 on the west side of the creek has been 

 trampled, and the site is accessed by an 

 unmaintained jeep trail. However, the five 

 clusters of Tr isetum or thochaetum are on the 

 east side of the creek, separated in most 

 cases from the undeveloped camping area by a 

 boggy meadow. These meadows are difficult 

 to traverse on foot; thus, the clusters are 

 largely protected by the nature of their 

 habitat. The other two sites are similarly 

 not directly threatened at this time. The 

 two meadows comprising the Granite Creek 

 Central site are the least accessible; they 

 are not visible from the Granite Creek Road. 



3. Potential threats: Future increases in 

 timber harvesting in the Grani te- Creek 

 drainage may impact the known sites and 

 other potential habitat. This would be 

 particularly true if future harvesting 

 continues in the forests along the level 

 drainage bottom. The meadows generally are 

 self-protecting, owing to a.) the
