Estimates of Site Index and Height Growth for Douglas-Fir in High-Elevation Forests of the Oregon-Washington Cascade Range: Curves and Tables for Field Application

摘要

Estimation equations for height growth and site index were derived from stem-analysis data of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) in the high-elevation 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.
