Enhanced mortality equations for trees in the mixed conifer zone of Southwest Oregon

Creator:

Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory

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...
