Probably because it is an old-growth forest, an ecosystem that has existed for about 200 years, undisturbed in this now-large city, the only area of its kind here. The ecosystem includes not only the four large preserved trees, but the undergrowth, smaller trees, and brush, the decaying flora, and the insects and fauna.
Can replanting any number of new, young, native and non-native trees replace what they just cut down? Wasn't a microcosm of our own West Tennessee old forest just as valuable an exhibit as a Grand Teton reproduction? And who says the old forest didn't have its own unique "use", as just that, undisturbed land that perhaps Marcus Winchester or the Native Americans saw?
I don't know anything about the new project. I am not commenting on the pros or cons of what happened about the highway all those years ago. I am only commenting on what we had left of the Old Forest and what has now happened to it. The zoo has been encroaching on the forest for some years now, i.e. all the trees that have been torn down for the maintenance buildings on the east side. Justify that.
I doubt many of you know much about the new project either, but you make fun of tree huggers and attempt to justify the destruction of a large number of trees.
I get tired of seemingly high-handed, short-sighted city bureaucrats just hauling off and doing things that are irreversible and high-impact with no input or even notice to the citizens of this city or the neighbors. Too many wonderful elements of this city have been lost to future generations forever, from old homes in Midtown and Downtown to green spaces. Just general comments from me.
