Abstract:: A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...

Creator:: Woods, John B. (John Burton), 1890- and Hann, John H.
Abstract:: "One of the basic problems of forest management is that of restoring to productivity denuded areas which cannot be expected to restock through natural means. The most efficient method of regenerating such lands is that method which provides adequate restocking in the shortest time with the least expense. Successful direct...

Creator:: Tesch, S. D., Mann, John William, and Oregon State University. Forest Research Laboratory
Abstract:: Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...

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...

Abstract:: Our diagram is intended to provide general guidance in density management of red alder. The management zone defines a reasonable compromise between individual-tree and stand growth and mortality. Factors considered in its formation include desired tree size at harvest, growth rate, and yield per acre. Social and legal constraints, as...
