Creator:: Dilworth, J. R. (John Richard), 1914- and Oregon State University. Forest Research Laboratory
Abstract:: Young western hemlock stands in the Coast Range of Oregon will contribute to the commercial timber supply of the region in the future, the extent of the contribution depending on environmental and cultural factors. The relative diameter and volume growth of crop-trees in the stands will be increased substantially by...

Creator:: Newton, Michael, 1932- and Oregon State University. Forest Research Laboratory
Abstract:: The response of western hemlock (Tsuga heterophylla [Raf.] Sarg.) to two methods of site preparation for planting was compared. One site was cleared of mature brush by the "brown-crush-and-burn" method. The other was partially cleared by spraying with herbicides. Seedlings lifted and planted in December, January, February, and April were...

Creator:: Ruppert, William J., Graham, R. D. (Robert D.), and Oregon State University. Forest Research Laboratory
Abstract:: The steadily increasing costs of raw materials, of the treated products, and of their replacement in service, as well as the steadily shrinking supply of preferred species, prompted a forum at Oregon State University on May 15, 1973 "to encourage the use of western hemlock and western fuss for poles...

Creator:: Espenas, Leif D., Oregon State University. Forest Research Laboratory, and Oregon State University. School of Forestry
Abstract:: Moisture content and shrinkage were determined on specimens equilibrated at two conditions for equilibrium moisture content (EMC) at room temperature after the specimens had been dried under a variety of constant temperatures with constant EMC's. Moisture content at room temperature equilibrium was less for specimens dried at high temperature than...

Creator:: Kozlik, Charles J. and Oregon State University. Forest Research Laboratory
Abstract:: To test the effects of kiln-drying on strength properties of Douglas fir and western hemlock, temperatures to 230 F, conditions for equilibrium moisture contents of 6 percent and 12 percent, and prolonged heating were investigated. Prolonged heating and choice of conditions for 6 percent or 12 percent equilibrium moisture content...

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...
