Selected Research Activities
  • Forest Productivity Research Cooperative (FPC).This is a research partnership among Virginia Tech, North Carolina State University, and the University of Concepcion in Chile that is supported by forest  industry in the United States and South America. Currently there are more than 50 forest industry organizations participating in the Cooperative which has an annual budget in excess of $800.000. The mission of the Cooperative is to integrate research, education and technology transfer to increase the productivity, profitability and sustainability of plantation forestry throughout the Americas. Dr. Fox serves as Co-Director of the Forest Productivity Cooperative. www.forestproductivity.org
  • NSF Center for Advanced Forestry Systems (CAFS).  The Center for Advanced Forestry Systems is a National Science Foundation Industry/University Cooperative Research Center that brings together top forestry research programs in the United States with industry members to solve complex forest management problems. The mission of CAFS is to optimize genetic and silvicultural systems to produce high-quality forest raw materials for new and existing products.  Dr. Fox serves as the Site Director for CAFS at Virginia Tech.  www.cnr.ncsu.edu/fer/cafs.
  • PINEMAP (Pine Integrated Network: Education Mitigation and Adaptation Project).  PINEMAP integrates research, extension, and education to enable southern pine landowners to manage forests to increase carbon sequestration; increase efficiency of nitrogen and other fertilizer inputs; and adapt forest management approaches to increase forest resilience and sustainability under variable climates. PINEMAP focuses on the 20 million acres of planted pine forests managed by private landowners in the Atlantic and Gulf coastal states from Virginia to Texas, plus Arkansas and Oklahoma. These forests provide critical economic and ecological services to U.S. citizens. Southeastern forests contain 1/3 of the contiguous U.S. forest carbon and form the backbone of an industry that supplies 16% of global industrial wood, 5.5% of the jobs, and 7.5% of the industrial economic activity of the region. Dr. Fox serves as the Silviculture and Ecophysiolgy Aim Leader and the Integration Leader for PINEMAP.  www.pinemap.org.
  • Use of Stable Isotopes to Evaluate Uptake and Environmental Fate of Nitrogen Fertilizers in Forest Ecosystems.   This project is using 15N labeled N fertilizers to evaluate their uptake, transformations and environmental fate in forest ecosystems.   We are comparing conventional fertilizers such as urea with enhanced efficiency fertilizers that include polymer coated urea and NBPT treated urea.  The goal of this research is to improve nutrient use efficiency and reduced loses through volatilization and leaching following fertilization of forest ecosystems. Research installations are located throughout the South in loblolly pine plantations.
  • Application of Biosolids to Forests.We are working with the Washington DC Council of Governments to evaluate the impacts of biosolids applications on forest growth, nutrient dynamics and water quality in Virginia.
  • Restoring Sustainable Forests on Appalachian Strip Mined Lands.We are working to restore productive forests to lands that were strip mined for coal in Virginia, West Virginia and Ohio. Prior to mining, most of these lands supported stands of mixed hardwoods. We are comparing site preparation, planting and subsequent management practices required to successfully reestablish white pine, hybrid poplar and mixed stands of native hardwoods on reclaimed strip mines. This work is in cooperation with the Powell River Project.  www.prp.cses.vt.edu.
  • Impact of Weed Control and Fertilization on Growth of Pine Plantations.This project is evaluating the effect of intensive management on the growth of White pine, shortleaf pine, Virginia pine and Loblolly pine plantains in the Virginia Piedmont. A factorial combination of weed control and annual fertilization is being applied to these stands. This study is being conducted at the Virginia Tech Reynolds Homestead Research Center. www.arec.vaes.vt.edu/reynolds-homestead
  • The Effects of Alternative Regeneration Methods on Hardwood Regeneration in Natural Hardwood Stands the Appalachian Region. We are evaluating the effects of alternative silvicultural systems including clearcuting, shelterwood, leave-tree, and group selection on species composition and growth of upland hardwoods in the Appalachian Mountains of Virginia and West Virginia. The goal of this project is to develop sustainable forest management practices for the Appalachian hardwood forests. It is a cooperative project with USDA Forest Service, Southern Research Station and the Bent Creek Experiment Forest.
