Edmund Hayes Professor in Silviculture Alternatives
My recent and future work aims at developing silvicultural treatments that maintain or encourage ecosystem adaptability, while providing income, timber, wildlife habitat, clean water, and other goods at the same time. I work on several experiments that investigate management impacts on vegetation structure and compositions. I am also interested in the question, which spatial scale are most influential on ecosystem processes. For example, under which conditions will landscape level factors override stand level silvicultural treatment or alternatively, under which conditions can small scale silvicultural treatments lead to conditions that override landscape level factors, such as climate change.
