Equations for predicting height to crown base for fourteen tree species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

Diameter growth equations for fourteen tree species in Southwest Oregon

Creator:: Hann, David W., Larsen, David R., and Oregon State University. Forest Research Laboratory
Abstract:: 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,...

Equations and tables predicting gross total stem volumes in cubic feet for six major conifers of southwest Oregon

Creator:: Hann, David W., Walters, David K., Clyde, Merlise A., and Oregon State University. Forest Research Laboratory
Abstract:: 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...

Equations for predicting the largest crown width of stand-grown trees in western Oregon

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Largest crown width (LCW) equations for stand-grown trees were developed for 14 tree species found in western Oregon. The equations are used in the growth-and-yield model ORGANON and in the stand-visualization program VIZ4ST. They were constructed such that LCW equals the maximum crown width of open-grown trees when the crown...
