Research Interests

I am interested in developing a better understanding of the role of wildland fire as a natural ecosystem process and applying that knowledge to help guide the stewardship of this process in wilderness. Research activities broadly include:

  • Quantifying the biophysical drivers of fire regimes.
  • Analyzing interactions among fire regimes, climate, and vegetation pattern.
  • Exploring the implications of fire suppression and our ability to restore fire as an ecosystem process.
  • Investigating the effects of global climatic change on fire regimes.



Ph.D., Ecology, 1998. - Colorado State University, Fort Collins, CO. Dissertation: Climate, Forest Pattern, and Surface Fire Regimes in the Sierra Nevada, California.
M.S., Forest Sciences, 1994. - Colorado State University, Fort Collins, CO. Thesis: A model of the interactions among climate, fire, and forest pattern in the Sierra Nevada.
B.S., Electrical Engineering, 1985.- Pennsylvania State University, State College, PA.


After a brief career as an engineer, Carol has found much more satisfaction in the field of ecology. As a graduate student, she developed and used a simulation model to study the interactions among climate, fire, and forest pattern in the Sierra Nevada of California.

After a postdoctoral appointment at the Aldo Leopold Wilderness Research Institute and The University of Montana School of Forestry, she became the fire ecologist here at the Institute. Her program of research seeks to help land managers understand how to include wildland fire as an ecological process to landscapes.

Research Projects

Current (PI or co-PI):

  • Improving our understanding of the ability of wildland fire to act as a fuel treatment (National Fire Plan, FY15-FY17)
  • A science program to support management of fire as a natural process (National Fire Plan, FY16-FY19):
    • Using wilderness as a natural benchmark for understanding fire regimes.
    • Fire risk analysis to support managed wildfire.
    • Assessing and understanding fire-facilitated ecosystem change.
    • Understanding the role of fire refugia in promoting ecosystem resilience.
    • Synthesizing lessons from the history of wilderness fire management.
  • Identifying ecological and social resilience in fire-prone landscapes (Joint Fire Sciences Program, FY16-FY19)
