STUDY PROCEDURES SAMPLING The study trees were selected from about 100 sample areas throughout the range of Douglas-fir in California, Oregon, and Washington. Saw logs and veneer blocks were processed at 10 mills as shown in figure 1. About one-third of the trees selected in each sample area were designated for veneer processing.

The "veneer" trees were randomly selected from pairs of trees whose physical characteristics matched as nearly as possible. One of these trees was included in the veneer study and one in the lumber recovery study. The tree pairs were selected to represent the range of tree size and quality in west-side Douglas-fir commer- cial sawtimber. The sample areas were located to provide the desired stratifica- tion of the main environmental factors of forest type, stand density, elevation, and aspect. Within each area, individual trees were selected on the basis of tree size and log quality. The study trees were felled and bucked into long logs, following log produc- tion practices as similar as possible to those of each cooperating mill. Trees designated as veneer trees were bucked into nominal 8-foot peeler blocks. The blocks from the entire tree were usually sent to the veneer mill. Two requirements for blocks sent to the veneer mill were diameters large enough (about 10 inches) and blocks sound enough to hold in lathe chucks. Each log was tagged in the woods to identify its origin by sample area, tree number, and position in the tree. The log samples processed at each mill and the combined sample represented the timber size and quality available over the extensive range of Coast Douglas-fir in California, Oregon, and Washington.
