Abstract

Lumber recovery information from 942 logs from old- and young-growth ponderosa pine (Pinus ponderosa Dougl. ex Laws.) trees in northern California is presented. More than 58 percent of the lumber volume was found in 5/4 Shop, Moulding, and Select grades. About 25 percent of the total lumber volume was Moulding, and 24 percent was Standard and Better Dimension. Lumber volume recovery is presented on the basis of cubic feet and board feet. Volume recovery varied by scaling diameter but not by log grade. Value recovery and percent volume by lumber grade did vary by log grade and diameter, but no difference was found between the grade 1 and the grade 2 logs.
