Curriculum Vitae: View/Download CV
Christopher Keyes is Associate Research Professor of Silviculture in the Department of Forest Management, and is Director of the Applied Forest Management Program (AFMP), a research and outreach unit of the Montana Forest and Conservation Experiment Station. Chris operates the AFMP Experimental Seedling Nursery, a reforestation seedling nursery focused on research and hands-on training in the propagation of conifers and broadleaf plants. He currently serves as associate editor for the Western Journal of Applied Forestry, outplanting advisor for the Lebanon Reforestation Initiative, Chair of the Inland Empire Reforestation Council, UM representative to the Inland Empire Tree Improvement Cooperative, and Deputy Coordinator of the IUFRO Temperate Forest Regeneration Working Party. Previously he was Assistant Professor of Silviculture at Humboldt State University (2001-2007).
Ph.D. 2000, Silviculture and Forest Regeneration, Oregon State University
M.S. 1996, Silviculture and Forest Stand Dynamics, University of Montana
B.A. 1990, International Development, Holy Cross College
Multiple-Resource Silviculture (FORS 347)
Chris and his colleagues test and evaluate innovative silvicultural practices in support of the AFMP mission: To develop and promote silvicultural tools and techniques for the restoration and renewal of western forests. Research and outreach efforts directly address challenges identified by forest stewards and researchers, with emphasis on forest regeneration dynamics, reforestation methods, and silvicultural restoration techniques. Past and present clients include the US Forest Service, National Park Service, US Army Corps of Engineers, US Agency for International Development, MPG Ranch, and Sempervirens Fund.
