Branch samples collected from 23 plots in northern Idaho and western Montana in 1975 had a combined mean distribution of 3.13 fascicles/inch (1.23 fascicles/cm) of branch length. By subsampling, it is possible to determine cumulative lineal inches of branch necessary to obtain a sampling unit of 100 fascicles for a plot, eliminating the need for counting fascicles on each sample.
