Areas of Interest

Forest management decision-support tools, biotic disturbances, regeneration dynamics

Although recently retired from the Forest Service, I continue to be active in three areas. Primarily, I continue to support development of NED, a set of decision-support software tools for forest management for multiple benefits.

I still have an active study known as the Forest Ecosystem Research and Demonstration Area (FERDA) at Paul Smiths in the Adirondacks, examining the effects of various silvicultural practices on several different components of the forest, including the trees, vascular flora, deer browsing, and salamanders.

I am also staying active working with educators to develop environmental literacy components to public school curricula, especially through a project called "Moving Field Guides" through which we integrate dance and ecological learning.
