Crown profile equations were developed for stand-grown western hemlock (Tsuga heterophylla (Raf.) Sarg.) in northwest Oregon. The profile model uses a segmented approach, dividing the crown into an upper and lower portion at the point of the largest crown width (LCW). The model explains about 86% of the variation in...
Site index and height growth equations for mountain hemlock
(Tsuga mertensiana (Bong.) Carr.) were developed from 37 trees located
in the Deschutes Nationa1 Forest. Initial analysis indicated the need
for stratification by habitat type. Preliminary community classifications
were used to develop three strata for the study. Two approaches
to model...
Tarif access tables were developed for mountain hemlock [Tsuga mertensiana (Bong.) Carr.] on the Deschutes National Forest in the Central Oregon Cascade Mountains from an equation for cubic-foot volume including top and stump (CVTS). These tables provide access to the comprehensive tree-volume tarif system.
