Current Research

My current research focuses on two main topics. First, to help improve wilderness stewardship nation-wide, I'm leading interagency efforts to integrate the concept of “wilderness character” into planning, management operations, and monitoring.

The second focal area of my research is developing decision-support tools for whether ecological restoration actions should be taken in wilderness. For example, climate change is increasingly forcing wilderness managers to confront the very complex challenge of whether restoration actions should be taken inside wilderness to mitigate the effects of climate change. Part of this challenge is determining the primary or basic purpose for what a wilderness is managed for. These decision-support tools will integrate federal laws and policies, the most current scientific information, and the underlying ethical and philosophical meanings that commonly underlie most decisions yet are commonly not explicitly stated. The overall intent for these decision-support tools is to have a transparent, comprehensive, and systematic approach for making these fraught decisions.

Research Interests

My research is broadly aimed at developing the strategies and tools for improving wilderness stewardship nationwide, and specifically the knowledge needed to protect and sustain ecological systems in wilderness. Wilderness management decisions are based on scientific information as well as on agency policies and social values, and my research reaches into all of these topics.

Past Research

My recent past research has largely focused on developing the concept of wilderness character in practical terms that wilderness managers and others can apply in planning, management operations, and monitoring. This research laid the foundation for evaluating the outcomes of wilderness stewardship in preserving wilderness character, which is the primary mandate of the 1964 Wilderness Act and all subsequent wilderness legislation.

Why This Research is Important

Our nation's wilderness is unique and increasingly threatened from many different directions. Only by understanding what wilderness is and the outcomes of our stewardship can we as individuals and as a society truly value and sustain this resource. All of my research, past and present, is focused on understanding what wilderness is, the basis for how it's managed, and the outcome of this management. With this knowledge, my intent is to help improve wilderness stewardship and derive the enduring benefits from this unique resource of wilderness.

    Denali National Park and Preserve
    The recent development of an interagency strategy to monitor wilderness character allows on-the-ground managers and decision-makers to assess whether stewardship actions for an individual wilderness are fulfilling the legislative mandate to “preserve wilderness character.” By using credible data that are consistently collected, one can assess how wilderness character changes over time and evaluate how stewardship actions affect trends in wilderness character.

    Beginning in 2013, the Superior National Forest partnered with the Aldo Leopold Wilderness Research Institute to develop a map of threats to wilderness character in the BWCAW. The primary goal of this project was to spatially depict how threats to wilderness character vary in magnitude and extent across the wilderness. This project was also intended to improve our understanding of the current condition of wilderness character, contribute to planning efforts by facilitating the evaluation of broad-scale impacts to wilderness character, and create a baseline from which changing threats to wilderness character can be monitored over time.

    Altered disturbance regimes and changing ecosystem dynamics in wilderness areas have increased the importance of having an evaluation framework to support transparent decision-making for ecological restoration actions. A recently created wilderness evaluation framework questionnaire allows for improved communication between land management agencies and wilderness stakeholders.

    The purpose of this project was to develop an approach that spatially depicts threats to wilderness character and how they vary across the Saguaro Wilderness. The maps produced through this project depict the Saguaro Wilderness’ current degree of departure or degradation from an “optimal condition” of wilderness character. 
    As we approach the 50th anniversary of the Wilderness Act, the combination of rising population, land use and climate change with other landscape stressors is driving ecological restoration to be one of the single most important, challenging, and potentially litigious wilderness stewardship issues because decisions need to incorporate diverse legal, scientific and ethical considerations.
    In 2008, the interagency "Keeping It Wild" wilderness character monitoring strategy was published and the four wilderness managing agencies quickly embraced it. It established a scientifically sound and rigorous approach to developing comprehensive baseline data on the unique characteristics of each wilderness.
