Smoke from a nearby wildfire envelops a small stream in Interior Alaska.

Fire is the dominant ecological disturbance process in boreal forests and is natural and widespread. However, fire frequency, size and severity are increasing in Alaska owing to climate warming. Interactions among fire, climate, permafrost, vegetation and hydrologic and watershed processes are poorly understood, yet critical for conservation and management of boreal aquatic habitats in a changing environment. Our research will address this challenge on and around DoD lands in interior Alaska by combining a detailed field experiment and measurements with an integrated suite of spatially- and temporally-explicit climate, terrestrial, and aquatic habitat models to better our understanding of the effects of fire and climate change on aquatic communities in interior Alaska boreal ecosystems. Collaborators include the University of Alaska Fairbanks, USGS, Alaska Department of Fish and Game, U.S. Fish and Wildlife Service, U.S. Department of Defense, and the Alaska Fire Science Consortium. The two primary goals of this project are to, 1) quantify fire effects on watershed- and local-scale aquatic habitats and the response of aquatic organisms on and adjacent to DoD lands in interior Alaska, and 2) integrate models that predict climate, fire, vegetation, hydrologic, and thermal dynamics to assess aquatic habitat and population vulnerability under a changing climate on and adjacent to DoD lands in interior Alaska. We will incorporate results from both objectives using a structured decision making (SDM) approach to define management objectives, decision options, management scenarios, and conduct cost-benefit analyses. The final product will be a web-based decision support tool developed to inform decision making.
