Resource Type:: Technical Report
Full Text:: - dependent stand model for Douglas-fir. Indices developed by other authors also require data on intertree

Modeling crown profile of Douglas-fir in the Western Willamette Valley

Creator:: Mortzheim, Joseph T.
Abstract:: Crown profile was modeled using a system of equations with three components. The first equation predicts the maximum crown width of an open grown tree based on the tree's diameter at breast height. The second equation modifies maximum crown width to represent the largest width of the crown in stand...

Development of tree height and diameter growth equations for mid-Willamette Valley Douglas-fir

Creator:: Ritchie, Martin W.
Abstract:: Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared...

Diameter growth equations for Douglas-fir and grand fir in the western Willamette Valley of Oregon

Creator:: Zumrawi, Abdel Azim, Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting diameter growth are an essential component of single-tree growth and yield models (Munro 1974). Diameter growth predictions are used to characterize individual-tree development and to project the growth of stand basal area and volume. Both diameter growth and basal area growth have been used as the dependent...

Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:: Weiskittel, Aaron R.
Abstract:: Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

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...

Hierarchical analysis of spatial pattern and processes of Douglas-fir forests using wavelet analysis

Creator:: Bradshaw, G. A.
Abstract:: There has been an increased interest in the quantification of pattern in ecological systems over the past years. This interest is motivated by the desire to construct valid models which extend across many scales. Spatial methods must quantify pattern, discriminate types of pattern, and relate hierarchical phenomena across scales. Wavelet...

Using Remote Sensing and Process-based Growth Modeling to Predict Forest Productivity Across Western Oregon

Creator:: McAdam, Erick
Abstract:: Accurate measurement of forest productivity is fundamental to understand the carbon balance of forested ecosystems. Recent changes in climate highlight the importance of developing methods to measure forest productivity so that sound economic and environmental decision can be made. Efforts to measure forest productivity across the landscape using remote sensing...
