Current Research

My research is directed towards conducting landscape-level studies of cutting disturbance, tree mortality, regeneration, and other factors affecting forest extent, composition, and sustainability. For the longer term, I hope to enhance ecological inventory and classification approaches by integrating remote sensing, GIS, and database management into a flexible system for understanding changes in forest resources and their associated spatial distribution. The impact of urbanization, parcelization, fragmentation, and land-use change complicate our ability to assess effects on composition and structure. Improved approaches will enhance our ability to construct forest community profiles based on accepted ecological criteria. I also hope to design and implement improved techniques for inventory of forested ecosystems.

Research Interests

Forest regeneration assessment (large scale) Understory-overstory relationships Impact of invasive species Regional sustainability assessments

Why This Research is Important

Knowledge of the health and sustainability of forested ecosystems at the landscape level is limited to traditional methodologies. Contemporary policy and management decisions require more timely, relevant and conclusive information that is spatially explicit. Quantitative analysis of FIA used in conjunction with auxiliary information provides the opportunity improve decisions that impact forest land and ultimately, human health and well being.
