Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing data from untreated research plots, we developed equations for predicting 5-yr diameter-growth rate (ΔD₅), 5-yr height-growth rate (ΔH₅), and 5-yr mortality rate (PM₅) for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the coastal region of the Pacific Northwest. These equations are revisions of the equations constructed in 1995–1997 for...

Abstract:: Reliable estimates of plant biomass and leaf surface area are essential for studying primary production, nutrient cycling, hydrology, wildlife management, and fire. This paper presents equations that can be used to make such estimates for most plant species-trees, shrubs, and herbs-dominant in western and central Oregon.' We also document the...

Creator:: Stine, R., Gordon, J. C., Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: Black cottonwood (Populus trichocarpa Torr. & Gray) cuttings were collected from five Oregon provenances along a north-south gradient. Cuttings from each provenance were grown for 1 year at two locations, one on the Willamette Valley floor and the other on the Valley margin. Survival at both locations was poor. Stem...

Creator:: Del Rio, Ernest, Berg, Alan B., and Oregon State University. Forest Research Laboratory
Abstract:: Growth was assessed for Douglasfir reproduction which had established naturally beneath three intensities of overstory thinning in a 65-year-old stand of Douglas-fir on the east side of the Oregon Coast Range. The age of advanced reproduction ranged from 4 to 15 years. Understory environments were described in terms of sunlight,...

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

Creator:: Lavender, Denis P., Overton, W. Scott, and Oregon State University. Forest Research Laboratory
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...
