Community Efforts

By working together, communities are finding better ways to control invasive weeds. Included here are just a few of the many organizations that have been created to manage weeds and their impacts.

Cooperative Weed Management Areas
A Cooperative Weed Management Area, or CWMA, is a locally-based organization that pools all available resources to control weeds within the management area. CWMA participants can include landowners, non-profit organizations, and local, state and federal agencies. Through combined efforts of CWMA participants, invasive weed management can be handled more effectively.

Jordan Valley CWMA
The Jordan Valley CWMA covers 4.5 million acres of land on both sides of the Oregon/Idaho border. In the summer of 2004, this CWMA mapped 50,000 acres of leafy spurge and other weed infestations. Trucks and ATV’s were used to spray leafy spurge and other weeds. Images showing the Jordan Valley CWMA at workMules carried herbicide into remote areas to spray leafy spurge infestations. For biological control, over 300,000 spurge-attacking insects were released. These intensive efforts knocked the leafy spurge invasion back to where individual landowners can handle follow-up control. Plots were set up to test the effectiveness of insects and herbicides on leafy spurge. Jordan Valley High School students help with the monitoring. This CWMA continues to manage leafy spurge, whitetop, perennial pepperweed, and scotch thistle.

Utah-Idaho CWMA
In 1997, neighbors along the Utah/Idaho border created the Utah-Idaho CWMA. This group of land management agencies and private partners monitors 6.5 million acres, in five counties, for 43 different weeds. Together, they help each other tackle large scale noxious weed projects that cross over different properties boundaries. The group has taken on projects against leafy spurge, spotted knapweed, yellow starthistle, and dyer’s woad. You can learn more at www.utah-idahocwma.org.



Wildfire Support Group
Ranchers in Winnemucca, Nevada have partnered with the Bureau of Land Management (BLM) through the Wildfire Support Group.

The ranchers are often closer to fires than BLM personnel, and can determine whether reported smoke is from a wildfire or a planned burn. The group also helps to rehabilitate lands that have recently burned.



Eastern Nevada Landscape Coalition

They undertake large restoration projects in eastern Nevada and throughout the Great Basin. Most of these projects take place on public land. The coalition works closely with several CWMA’s to control invasive weeds throughout their restoration efforts. To find out more, visit www.envlc.org.
