Rangeland Weeds and Pests

The direct annual cost to monitor and control invasive plants in California is $82 million, and indirect economic impacts are even larger. Despite disparate efforts, noxious weeds are continuing to invade rangelands and other working landscapes, highlighting the need for approaches that maximize cost effectiveness of reduced-risk practices while promoting biodiversity.

We held a series of workshops across California to share information on recent developments in Integrated Pest Management (IPM) rangeland research and field application with land managers. At these workshops, we deployed participant surveys to learn about local experiences and perceptions of rangeland weed control practices, and are currently working on a publication summarizing results. All workshop presentations and resources are available below! Download the workshop fact sheet here.
