Full Text:: Model Processors for the FLEX Modelling Paradigm by Curtis White and W. Scott Overton 25 UMFF

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....

Full Text:: the 5-Year Height Growth of Six Conifer Species in Southwest Oregon Martin W. Ritchie David W. Hann

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...

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Summaries from 49 published articles on site-index and dominant-height growth curves and equations are presented for 20 tree species or species groups found in California, Oregon, Washington, British Columbia, southeastern Alaska, Idaho, and western Montana. The summaries are organized by species. Each summary describes the modeling approach, type of curves/equations,...

Full Text:: FOR SPECIES IN THE PACIFIC NORTHWEST AND CALIFORNIA by David W. Hann Research Contribution 7 March

Creator:: Larsen, David R., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting total height as a function of diameter at breast height are presented for 17 tree species from southwest Oregon. Because basal area and site index often influence tree height, additional equations are presented which may include either or both of these as independent variables. Equation coefficients were...

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Summaries from 49 published articles on tree volume and taper equations are presented for 39 tree species found in California, Oregon, Washington, British Columbia, southeast Alaska, Idaho, and western Montana. The summaries are organized by species and then by type of equation (volume or taper). Each summary describes the types...

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,...

Full Text:: Diameter Growth Equations for Fourteen Tree Species in Southwest Oregon David W. Hann David R. Larsen

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr diameter-growth rate of a tree are presented for eight conifer and nine hardwood tree species from southwest Oregon. Equation parameters for undamaged and damaged trees combined were estimated by weighted nonlinear regression. The resulting equation for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] explained more than 71%...
