DescriptionYields for high-survival, unthinned ponderosa pine (Pinus ponderosa Laws.) plantations in northern California are estimated. Stems of 367 trees in 12 plantations were analyzed to produce a growth model simulating stand yields. Diameter, basal area, and net cubic volume yields by Site Indices50 40 through 120 are tabulated for stands ranging in age between 10 and 50 years and in spacing between 6 by 6 and 12 by 12 feet. Tables also show diameter distributions by crown classes and stem volumes in cubic feet for plantation-grown ponderosa pine. These data provide both a standard with which to compare the effects of management decisions, and a performance goal.
