The Role of Wildfire in Ecosystems

The term fire regime refers to the kind of fire that typically occurs in an area and the effects that a particular type of burning has on the vegetation. Fire regimes are described by fire frequency (how often fires occur), fire intensity (whether the fires that burn are mostly surface fires that burn ground vegetation or crown fires that burn on the ground and consume vegetation in the canopy), and the pattern of vegetation that the fires create. Scientists generally recognize four fire regimes in western Montana: Nonlethal, Mid-Elevation Mixed, Lethal, High-Elevation Mixed (although their names can vary from region to region). Use the buttons below to explore each fire regime.
