DescriptionEstimation equations for height growth and site index were derived from stem-analysis data of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii) in the highelevation forests of the Cascade Range in Oregon and Washington. Two sets of height-growth and site-index estimation curves and tables produced from previously published equations are presented-one set with U.S. customary units of measure and another set with metric units. These curves and tables were designed for use in the field by forest managers.
