Additionally, increased <br />vehicle travel could spread noxious weed <br />species into the area. New access roads and <br />removal of Garnbel oak allowing for greater <br />movement by livestock could also increase <br />weed spread. As a result, the potential for <br />noxious weed establishment would increase <br />over current infestation rates with increased <br />travel in the area and ground disturbance <br />affecting plant communities in the project area. <br />To address this issue, design criteria require a <br />herbicide use and weed control plan be <br />approved by the Forest Service, annual weed <br />monitoring as part of the weed control plan, <br />MDW pad seeding and mulching, and power- <br />washing project vehicles. Surface disturbance <br />and reductions in vegetative cover would be <br />mitigated by seeding and mulching disturbance <br />areas including pads and staging areas, as well <br />as providing resource competition if noxious <br />weeds do enter an area. Power-washing <br />vehicles and equipment would reduce the <br />probability weed seeds would be transported to <br />Deer Creek Ventilation Shaft and E Seam Methane Drainage Wells FEIS <br />89 <br />
