The Douglas Fir region of Washington and Oregon lies between the crest of the Cascade Mountains and the Pacific Ocean and extends southward from British Columbia almost to the California line. In this region title to the privately-owned forest land is vested in some 40,000 individuals and companies. To attempt to voice the attitude of so large a number of land owners whould be both presumptuous and impossible. However, among the owners and operators who produce a large proportion of the forest products in this region, there are certain land management principles upon which there seems to be widespread agreement.
