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...

A key to the literature presenting site-index and dominant-height-growth curves and equations for species in the Pacific Northwest and California

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,...

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...

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...
