The Historical Role Of Fire On The Bitterroot National Forest PDF Download

Excerpt from The Historical Role of Fire on the Bitterroot National Forest Presents frequencies, intensities, and influences of fire on stand structure and composition on the Bitterroot National Forest in west central Montana. Three study areas were established, each having a wide range of elevations and forest types. Findings are based upon study of nearly 900 individual fire scars on living trees, and on age classes of shade - intolerant trees attributable to fire. During the period from 1600 to 1900 fires were frequent in most habitat types, and substantial amounts of forest survived most fires. Some high-intensity stand-destroying fires were also detected in cer tain habitat types on each study area. Results show that fire was historically a major force in stand development, but that it has been of minor significance during the past 50 years, possibly because of organized fire suppression.
