Book Description
This report summarizes the results of lumber recovery studies at four sawmills in western Oregon and western Washington; two dimension mills, one grade mill, and one timber mill were included. Results from individual mills are reported and discussed. The four mills were also combined to approximate "average" conversion of logs to lumber for the region. Recovery information is presented by diameter and log grade for lumber volume, lumber grade, and lumber and log value.

Book Description
Excerpt from Lumber Recovery of Douglas-Fir From the Coast and Cascade Ranges of Oregon and Washington Volume recovery differed by log diameter, among mills, and by the units used to measure both logs and lumber, and may differ by whether the logs are measured as they come from the woods or after they have been bucked to mill lengths. Regres sion curves of recovery ratio, lumber recovery factor, or cubic recovery percent are plotted for both woods-length and mill-length logs. The cubic recovery percent for the combined mills reached about 76 percent of thalog volume for logs greater than 20 inches. Recovery ratio ranged from 225 to 130 percent across diameter.
