Description: Diameter, height, and volume growth and yield are given for plots thinned to 1000, 500, 250, 125, and 62 trees per acre in a 40- to 70-year-old stand of suppressed ponderosa pine (Pinus ponderosa Dougl. ex Laws.) saplings in central Oregon. Trees averaged about 1-inch in diameter and 8 feet in height at the time of thinning. Considerations for choosing tree spacing for precommercial thinning in this type of stand are discussed.
Keywords: Thinning effects, stand density, precommercial thinning, ponderosa pine, Pinus ponderosa
