Global Trophic Cascades Program is a research and educational program with the purpose of investigating the role of predators in structuring ecological communities. This program puts special emphasis on the role of potential keystone species in top-down community regulation, with linkages to biodiversity via trophic cascades.

A graduate degree concentration is available as part of the Trophic Cascades Program. Designed for students interested in topics that intersect forestry and wildlife science, this concentration provides an interdisciplinary approach to attaining sustainability of both forest and wildlife resources. Available within the Department of Forest Ecosystems and Society, the forestry/wildlife degree concentration involves dynamic interaction with faculty in both the College of Forestry and the Department of Fisheries & Wildlife. For more information, go to Graduate Studies.

The Leopold Project

The goal of the Leopold Project is to continue the work Aldo Leopold started on topics that intersect forestry and wildlife science and ecosystems. Aldo Leopold is a prime example of the usefulness of working across disciplines to solve complex natural resource problems.

The Leopold Project is our way to put formal emphasis on this multidisciplinary approach to the study, wise use, and conservation of natural resources. Much of our current work involves research on trophic cascades involving wolves, ungulates, and forest ecosystems. Use the links on the left to explore each project.
