Creator:: Hanus, Mark L., Hann, David W., and Marshall, David D.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter...

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,...

Creator:: Wang, Chao-huan and Hann, David W.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for 16 tree species from the central western Willamette Valley of Oregon. Foresters can use these "height-diameter" equations to avoid the time consuming task of measuring heights of all individual trees in an...

Abstract:: This report summarizes the results of work required by Senate Bill (SB) 148, enacted by the Oregon Legislature at its 1989 session and referenced in ORS 498.256. In response to SB 148 the Oregon Department of Fish and Wildlife (Department) developed standards to determine the needs, priorities, and estimated costs...

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...

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...

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,...

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...

Abstract:: The Optical Dynamics Experiment (ODEX) cruise of Oct and Nov 1982 occupied 1984 stations along a transect from the California coast at 35°N to a study area covering the subtropical front near 32°N, 142°W. This report presents data collected with spectral—radiometer instrument package and particle size distributions of discrete water...
