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

Ritchie, Martin W. (1985-04-25)

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 ...
Examining bias in estimating the response variable and assessing the effect of using alternative plot designs to measure predictor variables in diameter growth modeling

Zumrawi, Abdel Azim M. A. (1990-03-01)

Diameter growth of Douglas-fir (Pseudotsuqa menziesii (Mirb.) Franco) estimated from increment cores was compared with that obtained from repeated measurements of tree diameter on permanent plots located in two Douglas-f ...
