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.

The authors examine variation in the length of mean intervals between fires (occurring between the years 1600 and 1910) in sample units of various sizes, ranging from a point on the ground (single tree) to a large stand (200 to 800 acres; 80 to 320 hectares). Recommendations are made regarding appropriate sizes of sample units for fire history studies.
