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.

Book Description
Excerpt from Lumber Recovery From Large, Highly Defective, Low Grade Coast Douglas-Fir General product recovery information is presented in table 1. There was no significant relationship between percent of lumber recovery (overrun) and diameter, but there was a significant relationship between percent of lumber recovery and percent Of estimated defect. Lumber recovery percent increased as defect percent increased, indicating that recovery percent was more closely related to estimated defect than to diameter.

Book Description
Excerpt from Lumber Recovery From Old-Growth Coast Douglas-Fir The volume of commercial Coast Douglas-fir sawtimber is estimated to be in excess of 394 billion board feet. About 10 billion board feet of Coast Douglas fir is harvested annually. This is about 55 percent of the total softwood lumber production in the United States. There is an urgent need for better methods of appraising the quality of this important timber resource. Estimates of the recovery that can be obtained from Coast Douglas-fir sawtimber are needed by forest land managers, timber buyers, and timber processors for efficient utilization of the resource for lumber, veneer, pulp, or other products.
