Modeling Forest Trees and Stands

Dr. Harold Burkhart, University Distinguished Professor Department of Forest Resources and Environmental Conservation, College of Natural Resources and Environment, Virginia Tech University, Blacksburg, VA 24061, USA Interest Areas: Modeling forest stand dynamics, growth and yield; applying quantitative analysis techniques to forestry problems. B.S., Oklahoma State University (1965) M.S., University of Georgia (1967) Ph.D., University of Georgia (1969) Current research project Cooperative Research Program in Growth and Yield of Managed Stands of Loblolly Pine (Twelve industrial forestry firms plus Virginia Department of Forest Resources and Environmental Conservation and USDA Forest Service, 1979-present): The objective of this Cooperative is to develop loblolly pine tree growth and stand development models sufficiently flexible to account for the effects of intensive cultural practices, with output sufficiently detailed to allow for analyses of a full range of utilization options. TheCooperative maintains three large field studies: (1) a set of designed spacing trials, (2) a region-wide set of growth plots in intensively managed plantations, and (3) two pruning experiments and is part of the NSF Center for Advanced Forestry Systems.
