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.

FOR 599 - Aldo Leopold and Ecosystem Management (1)

Aldo Leopold and Ecosystem Management (1)

Literature review and discussion of Aldo Leopold’s body of work on ecology, natural resource management, and conservation. Topics to be covered in this seminar include Leopold’s developing theories on ungulate irruptions and the role of predation, and how these theories informed A Sand County Almanac and also inform ecosystem management today.

Class Objectives:

  1. To go beyond A Sand County Almanac and learn about the development of Aldo Leopold’s seminal theories on ecology, natural resource management, and conservation.

  2. To engage in thoughtful discussion on these theories and how they have influenced ecosystem management.

  3. To interact with leaders in natural resources science, management, and policy whose work has been influenced and inspired by Aldo Leopold.
