My students and I evaluate silvicultural and agroforestry approaches to achieving a variety of interrelated objectives, including watershed stabilization, fuelwood/biomass, timber, wildlife, recreation, and biodiversity ranging from rural to urbanized landscapes. Specific projects addressed challenges relating to the management of afforested bottomland and intact oak ecosystems. I also remain engaged in using agriculture and natural resources management to support security in unstable regions of the world.


Bottomland Hardwood forests, Afforestation and Reforestation, Mined Land Reclamation, Oak Ecosystem Management, Improving Productivity of Hardwood Plantations, Sustainable Watershed Development. Low-cost Urban Forestry Options for Small Communities, Methodologies for Controlling Tree Roots in Sewer Lines, Mixed Species Stand Dynamics, Vegetation Management, Temperate Agroforestry Systems, International Agriculture, Civilian-Military Partnerships
