Two sites, on Lewis & Clark National Forest lands 

 in the Front Range, are in areas used for horse 

 grazing. Of these, the Mortimer Gulch (007) site 

 appeared to be the most impacted; the drainage is 

 used for grazing by an adjacent guest ranch. 

 Light horse grazing was also evident at the 

 Arsenic Creek (012) site (D. Field, pers. obs.). 



Two other sites on U.S. Forest Service lands in 



the Front Range are in areas which may be subject 



to cattle grazing, but they do not currently 



appear to be threatened by this activity: 



Blacktail Gulch (006) 



Dry Fork Lange Creek (008) 



2. RECREATIONAL ACTIVITIES: Two populations studied 

 in 1988 occur in the Bob Marshall Wilderness Area: 



Butcher Mountain Meadows (004) 

 • White River (005) 



Neither of these appear to be seriously threatened 

 by recreational use at this time, although the 

 following observations were made. The Butcher 

 Mountain Meadows area is lightly used by 

 outfitters for hunting in the fall, well after the 

 growing season (Maria Ash, pers. comm.); the 

 Butcher Mountain trail (#133) does bisect the 

 area, but it is only lightly used, and does not 

 pass within the immediate area of the bog meadows 

 or the orchid subpopulations. If the meadows or 

 adjacent forests were to be used for hunting 

 camps, some impacts might occur. 



The White River site is along the south side of 

 the river, adjacent to a trail which is no longer 

 maintained; the current White River trail (#112) 

 follows the north shore. However, the south trail 

 is still used occasionally by outfitters and 

 U.S.F.S. personnel; it is becoming more difficult 

 to use, because landslides have removed portions 

 of the trail near the 0. rotundifolia site. 

 Although a portion of the habitat near the west 

 end of the site may have been impacted by these 

 slides, the majority of the habitat is intact and 

 not easily accessible. 



In the Front Range, four populations on Lewis & 

 Clark National Forest lands (Blacktail Gulch 

 (006), Clary Coulee (013), Mortimer Gulch (007),
