if it really all bares out that is some interesting stuff (although one wonders if they didn't study only plots that had been farmed or clear cut before or bruned over which might alter things)
one thing though is there has already been a reliably measured white pine over 200'- in the catalochee area of the smoky mtns - 207' a few years back, although the top recently broke. > To explain a bit more, if we want to speculate on the possibility > of white pines growing to 200, or the oft quoted height of 250 feet, > the idea that the 200 plus trees grew on the very best sites, and > those sites are now no longer available for growing pines because they > are now farmalnd, or whatever, should be less of a factor in our > speculations.
