• Prevent the introduction, reproduction, and spread of designated noxious weeds into and within Beaverhead County.
• Reduce the extent and density of established noxious weeds to a point the natural resource damage is within acceptable limits and, wherever possible, eradicated.
• Implement the most economical and effective weed control methods for the target weed.
• Implement an integrated management system using all appropriate methods or combination of methods.

The Beaverhead County Weed District follows the Early Detection, Rapid Response (EDRR) model. EDRR increases the likelihood that invasive species populations will be discovered, contained, and eradicated, slow the range of expansion, and decrease the need for costly long-term control efforts. A major aspect to EDRR is to utilize integrated weed management (IWM) strategies. IWM is a system planning and implementing methods that prevent, contain, or control noxious weeds. Methods include:

• Education/Awareness: Awareness programs develop public understanding of the threats that invasive, exotic plants pose to natural resources.
• Prevention/Early Detection: Prevention measures, such as washing equipment or vehicles, are the first line of attack against the spread of noxious weeds. In the long-term, it is more cost effective to prevent weeds from establishing rather than begin treatment after establishment.
• Inventory: Inventory provides necessary information for site-specific priority control objectives and for prescribing control methods and objectives.
• Treatment: There are a variety of treatment practices that can be implemented on the landscape, depending on target species, geographic location, and environmental attributes. Treatment types include biological, chemical, cultural, and mechanical controls.
• Monitoring: Monitoring is the collection of information to determine the effectiveness of management actions to meet the prescribed objectives. Various monitoring techniques can be used, such as EDDMapS, GPS databases, and photo points.
