Yes, it is sad to imagine the state of the forests before we arrived to
improve them.  Give me a break....

because of the dense cover and abundant food (berries on brambles and
insects).

disturbance, they rely on it.  Many species of oak fall into that
category -- they will not regenerate in great numbers without serious
disturbance.  Historically it was frequent spring fires but a clearcut
is a good alternative.  Which brings me to the second person whose
opinion I deeply respect:  Jim McCormac.  His PowerPoint on the
importance of forest caterpillars to the health of bird populations is
amazing.  Oak trees are incredibly important "caterpillar factories" so
we want to be sure we've got a steady supply of oaks up-and-coming.

pretty much was the same as yours..."Shouldn't there be a law against
that?".  But within 2 years it had probably the prettiest fall foliage
that I've seen -- the trees had sprouted back so thickly from the stumps
that you couldn't have walked through the place.  The density of the
foliage made the intensity of the colors incredible.  Now, 2 decades
later, the early successional aspect is long gone but it is still a nice
young forest.  Since then I've learned the first 2 points above that I
didn't know then.

managed, whether actively or passively, certain species will be favored

goal.  State forests offer a unique opportunity to do coordinated forest
management with timelines over a century and create habitat that is in
significant decline throughout the Appalachian area.  My opinion about
clearcuts has definitely changed now that I understand the place they
have in the ecosystem.  Humans too often want to keep things "status
quo" whereas wildlife has evolved under realms of disturbance and we do
a disservice to the wildlife by not providing disturbances.
