On the Stauffer road, knapweed occurs occasionally from German Gulch tc 

 Little Gulch (NE1/4 Section 30). From Little Gulch east, knapweed 

 increases along the right-of-way. 



The Miles Crossing option has low populations of noxious weeds in 

 native grassland and shrubland. Knapweed increases on lower slopes in 

 Sections 16 end 17 where the route approaches historic disturbances 

 from the railroad and activities at Miles Crossing. 



The Spangler option (new construction only) has low populations of 

 knapweed in the Nl/2 Section 14 and Sl/2 Section 11, increasing 

 substantially to the north. 



The Butte-Silver Bow Weed Control Board lists several weeds in addition 

 to those on the state list (Leo Mock, pers. comm.), however they were 

 not identified along the access road options. Several weedy species 

 not listed as noxious were identified including musk thistle ( Carduus 

 nutans) , henbane (Hyosc.va.mus niger), butter-and-eggs ( Lineria vulgaris ) 

 and flannel mullein ( Verbascu m th apsus ).
