Effects of Wildfire on Streams

This is a long-term (>25 yr.) study that was initiated by Dr. Minshall and has been continued by Dr. Baxter, students and collaborators since 2005. It is aimed at defining the recovery sequence for stream communities following wildfire and testing stream ecosystem theory. Environmental, population, and community-level responses have been measured in streams, immediately after fire and over the subsequent 1 to 20 years. In addition, several streams subjected to wildfire 50 years previously have been examined. Research is focused on forested watersheds in the Frank Church Wilderness of central Idaho and Yellowstone National Park. These studies provide valuable insights into the fundamental processes operating in stream ecosystems, as well as information useful to resource managers concerned with the effects of fire, the establishment of guidelines concerning fire in wilderness areas, and strategies for watershed and stream habitat rehabilitation following fire.
