1a. Objectives (from AD-416):
1) Assess the extent and impacts of cheatgrass/medusahead and their management on ecosystems; 2) Demonstrate state-of-the-art management strategies; 3) Conduct research to overcome barriers to the project's success, enhance the project, and fill information-gaps; 4) Provide education and technology transfer to those managing land in the Great Basin; and 5) Create decision-support products and tools that will have a sustained impact on managing cheatgrass/medusahead in the Great Basin and surrounding ecosystems into the future.
1b. Approach (from AD-416):
We will achieve this objective by combining the principles and concepts of EBIPM with state-of-the-art site-specific management of cheatgrass and medusahead infested rangeland and apply these strategies in 2-3 key watersheds in California, Idaho, Oregon, Nevada, and Utah.
3. Progress Report:
We implemented ecologically-based invasive plant management (EBIPM) practices and programs throughout the Great Basin region. Numerous research, demonstration projects and technology transfer efforts have provided land managers with a decision framework from which to make improved management decisions for managing invasive annual grasses. It is estimated that EBIPM is being adopted on and impacting over 4 million acres of public land alone, not counting the many private managers using EBIPM. Over 35 refereed journal articles filled knowledge gaps and validated the EBIPM framework. Land managers will have the necessary instructional and decision-support to implement EBIPM well into the future as a result of the products and training materials developed. All of the technology transfer materials created from this project are available on a website dedicated to EBIPM implementation – www.ebipm.org. This long term research project has yielded lasting impacts on the complicated pest management issues of western rangelands resulting in major advances in how invasive plant management is conducted.
