Gross Yields for Even-Aged Stands of Douglas-Fir and White or Grand Fir East of the Cascades in Oregon and Washington

摘要

Equations and tables for predicting net and gross yields for Douglas-fir and white (grand) fir in even-aged stands east of the Cascade Range in Oregon and Washington are presented. Data were collected in stands where height growth apparently was never suppressed by competing understory vegetation, high density, or top damage once the heights of the dominants became greater than 4.5 feet.
