Boise State University Theses and Dissertations
Because rangelands are characterized by more arid climates than forested regions, traditional methods of reconstructing fire histories (e.g. fire-scars from trees or charcoal preserved in lake sediments) are limited. Charcoal preserved in alluvial fans and stream terraces provide a means of reconstructing a record of fires and geomorphic responses in rangeland ecosystems.
This study used dated charcoal from fire-related deposits and deposit characteristics to determine a record of fire and geomorphic response. Twenty-five samples collected from terraces and alluvial fans within the Wood Creek study area indicate three major periods of fire-related activity. From 4,400 – 4,000 cal yr BP, …
