2011 Annual Report

1a. Objectives (from AD-416)
The overall objective is to develop and implement a comprehensive, regional Ecologically-Based Invasive Plant Management (EBIPM) program to restore ecosystems threatened and dominated by cheatgrass/medusahead in Jordan Valley and the Great Basin.

1b. Approach (from AD-416)
Oregon State University (OSU) and USDA, Agricultural Research Service (ARS) scientists will cooperate on a project to demonstrate and assess the potential of using a one-pass system, prescribed grazing, and plateau application strategies (refer to project proposal for more detailed information) to rehabilitate annual-grass infested rangelands across heterogeneous landscapes in Jordan Valley, OR and the Great Basin.

3. Progress Report
The goal of this project is to develop and implement a comprehensive, regional Ecologically-based Invasive Plant Management (EBIPM) program to restore ecosystems threatened and dominated by cheatgrass/ medusahead in the Jordan Valley watershed in the Great Basin which contributes directly to Subobjectives 1.1 and 1.2 of the Area-wide pest management project for annual grasses in the Great Basin. Substantial progress was made with outreach and education this past year. A poster presentation was made based on the analysis of 2 seasons of data at the annual meeting of Society of Range Management February 2011 in Billing, Montana. The poster titled “Assessment and Demonstration of Ecologically-based Medusahead and Cheatgrass Management in Jordan Valley, OR” provided evidence that the one-pass system for managing invasive grasses was effective and desired perennial grasses were establishing in the plots. Additionally, a field day was held at one of the Jordan Valley sites on June 6, 2011. Plot tours were planned and we had excellent registration for the field tour. Unfortunately, severe thunderstorms went through the area the morning of the field tour. We rescheduled at the Coordinated Weed Management Area (CWMA) office in Jordan Valley to give presentations and we still had nearly 30 people attend. The last sampling of the plots were completed in early July and the data will be analyzed and a manuscript prepared. Methods of project monitoring included meetings, e-mails, and phone calls.
