Density management guide for red alder

Creator:: Puettmann, Klaus J., DeBell, Dean S., Hibbs, David E., and Oregon State University. Forest Research Laboratory
Abstract:: Our diagram is intended to provide general guidance in density management of red alder. The management zone defines a reasonable compromise between individual-tree and stand growth and mortality. Factors considered in its formation include desired tree size at harvest, growth rate, and yield per acre. Social and legal constraints, as...

A key to the literature presenting tree volume and taper 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 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...

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,...

Hardwoods of the Pacific Northwest

Creator:: Niemiec, Stanley S. and Oregon State University. Forest Research Laboratory
Abstract:: This publication brings together in one place information on the general characteristics, biology and management, harvesting and utilization, wood characteristics, and related literature of Pacific Northwest hardwoods. Species included are bigleaf maple, black cottonwood, California black oak, California-laurel, giant chinkapin, Oregon ash, Oregon white oak, Pacific madrone, red alder, and...

Poplar chip production for Willamette Valley grass seed sites

Creator:: Withrow-Robinson, Bradford A., Hibbs, David E., Beuter, John H., and Oregon State University. Forest Research Laboratory
Abstract:: This publication is part of a 1-year project funded by the Oregon Department of Agriculture, Alternatives to Field Burning Program. Crop substitution is one strategy for reducing smoke from field burning. The objective of the project was to evaluate the potential for hybrid poplar as an alternative crop for poorly...

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...

Extending southwest Oregon's Douglas-fir dominant height growth equation to older ages

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Hann and Scrivani (1987) developed dominant height growth equations for Douglas- fir in southwest Oregon using stem analysis data sets with an upper age of approximately 125 years at breast height. The objective of this study was to determine whether these equations could be extrapolated for ages of 250 years...

Height-diameter equations for six species in the coastal regions of the Pacific Northwest

Creator:: Hanus, Mark L., Marshall, David D., and Hann, David W.
Abstract:: Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific Northwest. Foresters can use these “height–diameter” equations to avoid the time-consuming task of measuring heights of all individual trees in an inventory,...

Natural regeneration on staggered settings

Creator:: Lavender, Denis P., Bergman, Morris H., and Calvin, Lyle David, 1923-
Abstract:: In recent years much of the logging in the Douglas fir region has been by the staggered setting system. Consequently, the effects of this system upon natural coniferous regeneration have become increasingly important. This study was designed to analyze the effects of setting size and environmental factors upon natural regeneration...
