• Characterization and modeling of seasonal gas exchange in fertilized loblolly pine plantations (USDA Forest Service). This field study is measuring gas exchange in fertilized and unfertilized loblolly pine plantations as it is influenced by daily and seasonal changes in environmental parameters. Empirical models will be developed to more accurately predict photosynthesis in managed stands with the goal of improving process models.
• Development of Innovative Learning Techniques in Woody Plant Identification and Forest Biology (Virginia Forestry Education Foundation): We are developing several multimedia tutorials designed to teach woody plant identification and general forest biology. Programs will allow self-paced instruction and self-evaluation. Linkages to department home pages, instructor e-mail, bulletin boards, and student "chat rooms" will be integral parts.
• Quantifying Carbon efflux rates in managed loblolly pine plantations (USDA Forest Service, Westvaco Corp., NASA) We are measuring rates of carbon uptake and soil CO2 efflux in managed loblolly pine plantations. The results will be used in models aimed at estimating the role of southeastern forests in the global carbon budget.
