Yep - PNW forestry is a fairly reasonable solution, at least in the sense that it's sustainable as-is. But it's far from a natural condition for that area.

The comparison between relatively preserved parks and National Forests (e.g. Willamette) and the rest of the states forests is truly jarring.

For that matter, the same pattern can be seen across the country. Much of Pennsylvania is densely forested, but the entire state has only a few thousand scattered acres of old-growth woods.
