This project looks at long-term (i.e. 2000 year) trends in wildfire activity in the Canadian Rocky Mountains and foothills.
This research is an excellent example of not only how knowledge grows, but also the value of a coordinated long-term research program. When the Healthy Landscapes Program began 15 years ago, it was generally accepted that stand-replacing fires that killed all or most of the vegetation within their boundaries dominated foothills and boreal landscapes. Our findings from the Natural Wildfire Patterns research suggested that this assumption was questionable. Many natural wildfires left considerable amounts of live vegetation, and high levels of mortality were rare.
This got us thinking. If our long-held assumptions about historical fire severity are in dispute, then perhaps we should be reconsidering other historial fire regime parameters such as size and frequency.
To test this new theory, we invested in a pilot study north of Hinton, Alberta. That study provided enough evidence of a mixed fire regime to warrant the expansion to the Rocky Mountains. Current research activities involve academics from four Canadian Universities.
