Book Description
This report presents the findings of a study conducted to determine change in per acre timber volume on non-Federal timberlands in Washington from the mid-1960's to 1978-80. The basis for the-study was the measurement of 1,576 permanent plots at two occasions. The study findings include estimates of change in volume and of the components of change-growth, mortality, and timber cut. Timber volume increased during the period in eastern Washington but was apparently stable in western Washington. The findings differ, however, among owners and geographic areas. Tables of volume change, growth, harvest, and mortality are presented by owner group and geographic area.
