Development of tree height and diameter growth equations for mid-Willamette Valley Douglas-fir

Creator:

Ritchie, Martin W.

Abstract:

Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared...
