Absolutely agree with German here. "letting nature take its course" is an easy out for those people (unlike most of us on this forum) who don't understand that our species has already meddled with most of the planetary ecosystems. The best ideas usually come from field experience/data, evaluated with some understanding of how an ecosystem works.
As for "natural": cholera is natural, so is death in childbirth and a limited human lifespan. We are the ultimate, meddlesome primate species, constantly invoking the law of unintended consequences!

Funny how you say letting nature take it's course is not good, but then slam humans for meddling with ecosystems. Such as controlled burns and mechanical thinning of the forest?
And you are right Bob, in that thinning or other types of harvesting isn't the answer on every stand, nor did I claim it was. I was recently privy to a management plan put together by a consulting forester for a large tract. The area was broken up into several blocks based on conditions of the stands. The recommendations ranged from prescribed burning, to thinning, to doing absolutely nothing at all. That type of plan is the result of months of intense field work rather than armchair suggestions made with little experience in forest management. Plans then have to be approved by the Pinelands Commisssion, rather than implemented with carte blanche. As I already said, mistakes can be made and lessons can be learned as science advances, but I'll take scientific management over the alternative every time. My experience has been that pleasing everyone when managing public land is impossible, and only seems simple to those who have never had that responsibility.
