Researchers at the Pacific Northwest Research Station have completed over 100 forest product recovery studies over the past 40 years. Tree, log, and product data from these studies have been entered into a database, which will allow further analysis within, between, and across studies. Opportunities for analysis include stand-to-log-to-final product estimates of volume, quality, and value. Examples of possible database queries include determining the variation in recovery volume and product yield from different age or diameter classes, the relation between percentage of sound log volume and product yield, and the relation between product quality and age.
