OUR present forest trees are good. They are not perfect, though. They developed as the result of natural selection to fit various ecological niches in pre-white man forests. Our forest sites have changed and wild type trees are no longer in perfect equilibrium with their environment. Also, natural selection favored types which survived and reproduced best, not the types which would produce the best sawlogs or the best pulpwood.
