Equations are presented that predict individual-tree 5-year diameter growth, outside bark, for 14 tree species in southwest Oregon. The data used to develop the equations came from 19,245 trees sampled from 391 stands in the study area. These equations express diameter growth as a function of diameter at breast height,...
Models of stand growth and yield must include an estimate of mortality. For individual-tree/distance-independent growth-and-yield models. it is necessary (1) to predict the probability of death of individual trees and (2) to keep stand projections within reasonable biological limits (e.g., the maximum basal area that the stand can achieve). In...
Equations and tables predicting gross total stem volumes in cubic feet are presented for Douglas-fir, grand fir, white fir, ponderosa pine, sugar pine, and incense-cedar. The data were gathered in second-growth, mixed-conifer stands of southwest Oregon. The basic equations use diameter outside bark at breast height and total tree height...
Tables are presented that summarize 108 published articles on forest growth and yield in the Pacific Northwest. Each table describes the form of the information presented, the species to which the information is applicable, the data sources used to develop the information, the data needed to predict growth and yield,...
Using existing data from untreated research plots, we developed equations
for predicting 5-yr diameter-growth rate (ΔD₅), 5-yr height-growth
rate (ΔH₅), and 5-yr mortality rate (PM₅) for Douglas-fir [Pseudotsuga
menziesii (Mirb.) Franco] in the coastal region of the Pacific Northwest.
These equations are revisions of the equations constructed in 1995–1997
for...
