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...

Full Text:: MORTALITY EQUATIONS FOR TREES IN THE MIXED CONIFER ZONE OF SOUTHWEST OREGON by David W. Hann and Mark L

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%...

Full Text:: -RATE EQUATIONS FOR UNDAMAGED AND DAMAGED TREES IN SOUTHWEST OREGON by David W Hann Mark L Hanus

Creator:: Hanus, Mark L., Hann, David W., Marshall, David D., and Oregon State University. Forest Research Laboratory
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...
