Abstract:: Using existing data from untreated research plots, we developed equations for predicting 5-yr diameter-growth rate (ΔD₅), 5-yr height-growth rate (ΔH₅), and 5-yr mortality rate (PM₅) for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the coastal region of the Pacific Northwest. These equations are revisions of the equations constructed in 1995–1997 for...

Abstract:: Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...

Abstract:: 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...

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr height growth rate of a tree are presented for six conifer species from southwest Oregon. Equations for the combination of undamaged and damaged trees were estimated with weighted nonlinear regression techniques. These equations are being incorporated into the new southwest Oregon version of ORGANON, a...

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr diameter-growth rate of a tree are presented for eight conifer and nine hardwood tree species from southwest Oregon. Equation parameters for undamaged and damaged trees combined were estimated by weighted nonlinear regression. The resulting equation for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] explained more than 71%...

Abstract:: Trends in fee hunting in Oregon are examined, with particular emphasis on waterfowl in the western part of the state. Farmers with potential or existing waterfowl habitat in western Oregon were surveyed about their views on managing their lands for waterfowl. As incentives to such practices, they listed the financial...
