is 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 side. 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 C. passerinum 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 riverbank habitat is intact and not easily 

 accessible. 



The Mud Lake site occurs on the east side of the 

 lake, in the ecotone between the bog mat and the 

 adjacent forest. The northwest portion of the 

 meadow associated with Mud Lake is traversed by the 

 main South Fork Flathead River pack trail (#80), 

 which is heavily used. The trail is actually about 

 0.4 km. from the nearest portion of the C. 

 passerinum population, and the immediate site does 

 not appear to be impacted at this time. 



The Big Prairie Bridge site is on the shore of the 

 South Fork Flathead River, just west of the large 

 wooden pack bridge over the river. Although a 

 maintained trail does not follow the immediate shore 

 of the river here, the area is used for fishing, and 

 may occasionally be traversed on foot. 



In the Front Range, three populations (Blacktail 

 Gulch (006) , Clary Coulee (010) , and North Fork 

 Birch Creek (Oil)) are located near maintained 

 trails. In Blacktail Gulch, the trail (#223) is a 

 National Recreation Trail, and is fairly heavily 

 used for hiking and horseback riding. The C. 

 passerinum population is located along the east side 

 of the trail about 1 mile north of the trailhead. 

 Although it is directly adjacent to the trail, the 

 site does not appear to be impacted at this time. 

 The boggy seepage area is not easily traversed, and 

 is thus not likely to be heavily impacted by trail 

 use in the current situation. In Clary Coulee, the 

 northernmost subpopulation of C. passerinum is 

 partially traversed by a hiking trail (#177) . The 

 trail is steep, and eroded in places to 3-5 m. wide
