    Description

    This report notes the changes in timberland area and in timberland ownership that took place in western Oregon between 1961 and 1986. The data for the report were based on observations and measurements taken during three successive forest inventories of non-Federal lands in western Oregon. Estimates of change were based on repeat measurements of 1,465 permanent plots but older classification were revised to meet current definitions and standards.
