Changes in Land Use in Western Oregon between 1971-74 and 1982

摘要

Statistics are presented by county for western Oregon for four dominant land use classes on non-Federally owned land. The classes were primary forest, primary agriculture, low-density urban, and urban. Classes were determined from aerial photographs taken in 1971-74 and in 1982; by using these data, estimates of change for the period between photography were developed.
