Height growth and site index estimation equations andcorresponding curves were derived from stem analyses of Abiesprocera Rehd. in the Cascade Range of Oregon and Washington.These incorporate additional data and new site index estimationprocedures and replace previously published curves. Two setsof height growth and site index estimation curves and tablesare given--one set with U.S. units and another set with metricunits.
