Forest Research Laboratory, Hann, David W. 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 of dependent variables predicted by the equations and the geographic location, number of trees, range in DBH, and range in total height for trees in the sample used to develop the equations.

• 4. [Article] Equations for predicting the largest crown width of stand-grown trees in western Oregon

  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 ...

  Citation × Citation Citation Abstract Copy Title: Equations for predicting the largest crown width of stand-grown trees in western Oregon Author: Oregon State University. Forest Research Laboratory, Hann, David W. 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 ratio is equal to one. Tree measurements needed for the equations are diameter at breast height (in.), total tree height (ft), and crown length (ft).

• 10. [Article] Enhanced mortality equations for trees in the mixed conifer zone of Southwest Oregon

  Citation × Citation Citation Abstract Copy Title: Enhanced mortality equations for trees in the mixed conifer zone of Southwest Oregon Author: Hanus, Mark L., Oregon State University. Forest Research Laboratory, Hann, David W. Equations for predicting the probability of a tree's dying in the next 5 years are presented for eight conifer and eight hardwood tree species from southwest Oregon. A logistic equation form was used to characterize the probability of mortality. The parameters of the equation were estimated using weighted, maximum likelihood procedures. These equations are being incorporated into the new southwest Oregon version of ORGANON, a model for predicting stand development. In particular, the equations extend the previous model to older stands and and stands with a heavier component of hardwood tree species.
