Book Description
Excerpt from Gross Yields for Even-Aged Stands of Douglas-Fir and White or Grand Fir East of the Cascades in Oregon and Washington Stem analyses of selected sample trees in temporary sample plots in even - aged stands were used to cal culate gross periodic annual incre ments. Volume and basal area of the sample plots at the time of sampling were regarded as net volume and net basal area. Multiple regression methods were used to relate net basal area to site index and age at feet. Then net volume and periodic annual increment were related to site index, age at feet, and net basal area. Gross volume yield was obtained as a cumulative summary of gross volume increment from a breast-high age of 20 years plus the net volume at this age.
