Synergistic Activities

Editor-in-Chief Rangeland Ecology & Management, 2008–2015: Responsible for all academic aspects of publishing the premier international journal addressing global rangeland issues. Activities include management of the editorial board (26 members with a strong international presence), coordination with the managing and production editors at Allen Press, and numerous aspects of Journal promotion. The Journal receives over 200 submissions from authors world-wide and publishes 720 pages per year.

Academic Coordinator for USDA Rangeland CEAP, 2007-2011: Academic coordinator for the Conservation Effects Assessment Program (CEAP) of the USDA-NRCS Resource Inventory and Assessment Division. The goal of this national program is to provide an evidence-based assessment of the effectiveness of major rangeland conservation practices on environmental quality and ecosystem services. The current program involves nine academic teams, totaling 36 scientists. Recommendations of this initiative will inform policy makers of science-based priorities to effectively allocate funds to rangeland conservation systems in the current and subsequent Farm Bills.
