Effects of Noxious Weed Management 



Under the no-action alternative, noxious weeds may establish on 4 WD roads and onto dry 



vegetation sites by unauthorized vehicles or animal use. 



Effects of Alternatives 



The Montana County Noxious Weed Act (MCA 7-22-2102-2153) requires State agencies to 

 submit plans to manage noxious weeds where they occur, through planning and implementation 

 of integrated management measures of prevention, revegetation and control. The action 

 alternatives will involve ground-disturbing activities and traffic that have the potential to 

 introduce or spread noxious weeds in susceptible habitat types. For the action alternatives, an 

 Integrated Weed Management (IWM) approach was considered by DNRC and a combination of 

 prevention and revegetation measures are considered the most effective weed management 

 treatments for all proposed action alternatives. To reduce the possible introduction and spread of 

 weeds associated with this project, the following prevention measures would be implemented for 

 new road construction and areas of disturbance along the existing access road. 



• All road construction and harvest equipment would be cleaned of plant parts, mud 

 and weed seed to prevent the introduction of noxious weeds. Equipment will be 

 subject to inspection by forest officer prior to moving on site. 



• All newly disturbed soils on road cuts and wills would be promptly reseeded to 

 site adapted grasses to reduce weed encroachment and stabilize roads from 

 erosion. Within the course of the project areas that have not revegetated would be 

 reseeded. 



• DNRC will monitor the project area for noxious weeds for two years after harvest 

 operations. If noxious weeds are noted DNRC will develop a weed management 

 plan. 



Economics 



The cash flow analysis estimates the project revenues and costs from the different treatments. 

 This analysis estimates the cash flow from timber harvesting and non-administrative sale costs 

 for alternatives considered. DNRC does not have a formal accounting system to track costs for
