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.

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
