The forestry Dave's referring to has not been managed in a sustained
yield manner for decades - we've cut beyond sustained yield.
Also, clear cutting with replanting of single-aged, monoculture stands is
only one way of managing for sustained yield.
Another way is low-volume selective logging. There are a few private
companies that do this (a very few, most liquidate at a much higher
rate than the USFS has over the past 50 years). The best example
in Oregon, in our ponderosa pine country, did so for decades but
got sold upon the death of the patriarch. The new owners immediately
doubled the cut, of course.

Much closer to home, US law has required the USFS to do so since the
