Variation in Estimates of Fire Intervals: A Closer Look at Fire History on the Bitterroot National Forest

摘要

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 apoint 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.
