Reanalysis of the SMC-ORGANON equations for diameter-growth rate, height-growth rate, and mortality rate of Douglas-fir

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...

Stress-strain distribution in Douglas-fir beams within the plastic range

Creator:: Ramos, Agustin N., Jr. and Forest Products Laboratory (U.S.)
Abstract:: A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...

Examining bias in estimating the response variable and assessing the effect of using alternative plot designs to measure predictor variables in diameter growth modeling

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: Diameter growth of Douglas-fir (Pseudotsuqa menziesii (Mirb.) Franco) estimated from increment cores was compared with that obtained from repeated measurements of tree diameter on permanent plots located in two Douglas-fir study areas in the central Coast Range of Oregon. Growth was measured for a 6-year period (1979- 1985). Diameter growth...

Nonlinear models of height growth for Douglas-fir in southwestern Oregon

Creator:: Scrivani, John A.
Abstract:: A review is made of methods which assess the bias and non-normality of parameter estimates and predictions obtained with nonlinear regression. Particular emphasis is placed upon curvature measures of nonlinearity, related measures of parameter and prediction bias, and the effects of reparameterizations. Alternate models of individual tree height growth are...

Construction of regression models for predicting crown development in southwestern Oregon Douglas-fir

Creator:: Maguire, Douglas A. (Douglas Alan)
Abstract:: A branch mortality dating technique and whorl sampling strategy were implemented to model five-year crown recession from data collected on temporary plots. Twenty-eight Douglas-fir from two levels-of-growing- stock studies in Oregon and Washington were first dissected to validate the proposed dating technique and assess alternative sampling strategies. Branch mortalities in...

A model of forest nitrogen cycling to assess the effects of management intensity on long-term productivity in Douglas-fir forests of the Pacific Northwest

Creator:: Krzak, Joan
Abstract:: The objective of this study was to assess the effects of forest management intensity on long-term productivity of Pacific Northwest Douglas-fir forests. The components of management intensity included rotation length, timber utilization standard (whole tree or bole only), method of slash treatment (remove/burn or leave) and fertilization practice (urea nitrogen...
