Research Project: Continental Divide Cooperative Weed Management Area Agreement

Location: Range Sheep Production Efficiency Research

2013 Annual Report

1a. Objectives (from AD-416):
The noxious weed and invasive alien plant problem in the geographic area included in the Continental Divide CWMA is at a critical magnitude, causing environmental and economic depredation. The problem exists on public as well as private lands and control on only one or the other is ineffective. Resources are limited for both the private and the public sectors and cooperation among all land managers can improve the effectiveness of weed control efforts on all lands.

1b. Approach (from AD-416):
The representatives of the partners of the Continental Divide CWMA accept and support, on behalf of their organizations, the mission and goals of the CWMA as outlined in the Integrated Weed Management Plan and shall work together for the common good in controlling and eradicating noxious weeds and invasive alien plants. Information shall be shared among all parties so that control efforts can be coordinated. An integrated approach shall be used, applying site specific control methods, taking into consideration the magnitude of the problem, the terrain, possible environmental impacts, and other considerations.

3. Progress Report:
The goal of this agreement is to effectively identify, locate, treat, and manage infestations of noxious weeds. Progress was made by Agricultural Research Service (ARS) scientists in locating, identifying, treating and reporting spotted knapweed infestations on ARS lands. Accordingly, Continental Divide Cooperative Weed Management Area staff provided recommended weed-abatement biocontrol products and collected and recoded weed-abatement data. These activities will be repeated in FY2014. This collaboration supported Objective 2 of the parent project, which is focused on developing science-based grazing management strategies and decision support systems that can be used to guide managers to maintain or improve the ecological function of western rangelands.
