On the Farm Woodlot poor-quality red maples were poisoned to release balsam fir. The maple at the left is riddled with heart rot. These red maples occupied this site for 40 years and most of them now prove to be unmerchantable because of extensive heartrot. "Have 40 years been wasted? Can we anticipate this and prevent it? Is it worth it?"
