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,...

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,...

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...

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...

Photogrammetric uses of a new-generation analytical stereoplotter in forestry

Creator:: Kiser, James D. (James Donald)
Abstract:: The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...

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,...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

Disaggregative and individual-tree growth models in theory and application

Creator:: Ritchie, Martin W.
Abstract:: Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...

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...
