Almost the entire watershed of the Umpqua River lies within the boundaries of Douglas County. The heavily timbered county contains nearly of commercial forest lands and one of the oldest stands of old growth timber in the world. Approximately 25–30% of the labor force is employed in the forest products industry. Agriculture, mainly field crops, orchards, and livestock (particularly sheep ranching), is also important to the economy of the county. The land of Douglas County is roughly half-publicly and half-privately owned.
