Wildfire is an important disturbance agent in western Canadian forests, and land management and fire exclusion strategies have made the modern record of fires unrepresentative of the natural disturbance regime resulting in apparent landscape homogenization. This research uses a multiproxy fire history approach to reconstruct wildfire history in the Alberta Foothills, a landscape believed to be characterized by a mixed-severity regime. A pilot study was conducted in the summer of 2012 which involved the establishment of a sampling grid and the collection of fire scar and stand origin data from 16 plots. To date, stand establishment and fire years have been determined. These records will be supplemented by further sampling and extended using the macroscopic sedimentary charcoal record in hopes of understanding the spatial and temporal controls on changes to the wildfire regime in this area, as well as corroborating wildfire proxy records.
