Current Research

I am working with a team of scientists to forecast long-term, large-scale changes in Midwestern forest landscapes that result from natural disturbances and from alternative harvesting practices. I am using information on regional, national, and global patterns of wood consumption, forest growth, and timber harvest to identify issues related to sustainable forest management. I am working to understand factors associated with oak mortality and on methods to minimize its impact.

Why is This Important

Forecasting landscape change with simulation models is an essential quantitative tool for understanding the large-scale, long-term, cumulative effects of forest management. This knowledge is required for management of National Forests and equally crucial for understanding the combined effect of seemingly independent management decisions by thousands of private forestland owners on a single landscape. It is important to consider the effects of consumption of wood products on forest resources at home and abroad. In the U.S. we often transfer impacts of harvesting and consumption elsewhere and fail to consider the broader implications for forest sustainability.

Future Research

I will continue to work on issues related to forest sustainability and landscape-scale, cumulative impacts of forest management decisions. In the coming years I will place more emphasis on fire effects (wildfire and prescribed fire) and bio-energy production as it relates to theses issues.
