• Role of microtopography in northern hardwood tree growth, regeneration, and diversity

Research Interests

• Functional diversity of understory plant communities response to silvicultural treatments
• Adaptive silviculture for changing conditions

Why This Research is Important

Long term perspectives on a variety of approaches to forest management are exceptionally important as environmental conditions and societal values continue to change. My work focuses on ecological underpinnings of plant community dynamics in managed forests both at present and retrospectively over past decades. Analysis of past work provides a rare insight into long term trends and responses that cannot be detected in a short term study or even during one's career! In light of this, I have the fortunate opportunity to study decades of silvicultural research from earlier scientists to evaluate impacts on complex issues such as forest sustainability and ecosystem integrity. These research results will provide information and tools to adapt silvicultural systems to the changing needs of the future.
