Abstract:: Short-term heating of softwood veneer blocks temporarily softens the wood so that it can be peeled more readily. Heating reduces the depth of lathe checks and the likelihood of splitting and thereby increases the quality and quantity of veneer recovered. The softwood-plywood industry conventionally conditions blocks three ways: steaming blocks...

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:: Hermann, Richard K., Lavender, Denis P., and Oregon State University. Forest Research Laboratory
Abstract:: "We describe a test procedure developed during growth room and field trials for which we processed hundreds of test lots of seedlings, mainly Douglas-fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa), as well as lodgepole pine (Pinus contorta), Jeffrey pine (Pinus jeffreyi), and Sitka spruce (Picea sitchensis), noble fir (Abies...

Creator:: Bradshaw, George and Oregon State University. Forest Research Laboratory
Abstract:: Production rates, skidding costs, and soil disturbance were compared for two partial-cut units-one with preplanned skid trails and winching and one conventional unit-harvested with a Caterpillar D-7F. For the unit with preplanned skid trails and winching, production was 11 percent less, and skidding cost per unit volume was 29 percent...

Abstract:: "Control of competing vegetation during establishment is one of the key links in the chain of events leading to a new plantation and, ultimately, a productive forest resource. Experience has repeatedly shown that, without adequate site preparation, reforestation efforts almost inevitably will fail. Vegetation control during the establishment period by...

Abstract:: The effects of a range of thermoperiods and soil temperatures upon growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were studied. The seeds, of varieties glauca and menziesii, came from eight widely separated areas. Plants from both varieties made maximum growth with soil and air temperatures between 18 and 24...

Abstract:: Regression models of height growth and survival were fitted to aggregate data for trees, protected and not protected from animal damage, that had been surveyed on Douglas-fir and ponderosa pine plantations in Oregon and Washington. Animal damage significantly affected both height and survival. Dynamic programming analysis-using both soil expectation (Se)...

Abstract:: Mammal and bird damage recorded on Douglas-fir and ponderosa pine plots-randomly established in Oregon and Washington during 1963-64, then observed for 5 to 10 years-was evaluated for impact on survival and growth. In all, 194 plots were installed, and 10 of the 110 seedlings on each plot were caged to...
