Overview

  • Most of my research is now in the area of sustainable ecosystem management, applying concepts learned over 30 years in the study of native forest ecosystems to managed woodlots and pastures. One active project focuses on the nutrient and energy balances of the UNH’s first-in-the-nation Organic Dairy Research Farm. The goal of the project is to reduce dependence on external sources of energy and bedding, reduce the farm’s environmental footprint, and using static pile, aerobic composting techniques to generate heat energy for use on the farm. With USDA and AES support, the project is focused on providing research opportunities for both undergraduate and graduate students, and also maintains close ties with external stakeholders. This work is part of an overall approach to measuring and monitoring the Nitrogen footprint of the University and assessing the value of Life Cycle Analysis in determining environmental impacts.
