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.

Special Interests

Bottomland hardwood forests, afforestation and reforestation, oak ecosystem management, improving productivity of hardwood plantations, mixed forest stand dynamics, vegetation management, temperate agroforestry systems, restoration of highly disturbed lands, management options for sustainable landscapes, urban forestry for small communities, international agriculture and watershed development, civilian-military partnerships
