Excerpt from Forest Resources of the Ponderosa Pine Region of Washington and Oregon It is not enough to know that this region has 22 million acres of forest land and 127 billion board feet of saw timber. To reap the full economic benefits of this resource a detailed understanding of how it can be made to contribute most to the welfare of the people is necessary. Based upon this understanding, plans for adoption of sustained yield must be formulated and effectuated immediately, to avoid wasteful migra tion of industry and people that follows exhaustion of forest resources.

The highest service that forests of the Douglas-fir region can render is in support and stabilization of communities dependent on them. Forests support in one way or another about half the population of the region. To redeem this enormous responsibility for service, forests must furnish a permanent annual harvest of material equal at least to present production. This will required sustained-yield forest practice, including acceptance of the responsibilities of permanent ownership.
