One of the first published references to multiaged silviculture in ponderosa pine on national forests was by Clapp ().
He described systems of very heavy removals of approximately two-thirds of the volume and cutting cycles from 40 to 60 years. Old-growth forests once covered much of Oregon, but today less than 10 percent of our state’s heritage forests remain.
Much of what survives is found on US Forest Service and Bureau of Land Management lands that are still actively targeted for logging. You can read more about Oregon's old-growth forests in the Pacific Northwest Research. XThe average number of years for ponderosa pine seed- lings to attain a height of 4% feet was determined as a phase of a growth and yield study by counting the an- nual rings at the root collar of open grown seedlings in selectively cut stands.

In addition, the old-growth forests of the Northwest contained many alders, hemlocks, and other species that were not valuable for lumber.
Pinchot wanted to cut down these "wasteful" forests and replace them with managed forests that would produce lumber quickly. The ideal forest would be composed only of high-value trees like Douglas firs.
