Research Projects

Cooperative Research Program in Growth and Yield of Managed Stands of Loblolly Pine (Twenty industrial forestry firms plus Virginia Department of Forestry 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. The Cooperative maintains three large field studies: (1) a set of designed spacing trials, (2) growth plots in cloned plantings, (3) a region-wide set of growth plots in intensively managed plantations, and (4) two pruning experiments and is part of the NSF Center for Advanced Forestry Systems as well as the regional PINEMAP project.
