Sometimes, that's due to blights. We're losing a lot of beautiful, mature ash trees to emerald ash borers. So any tree with even a hint of them leads to immediate destruction. I have a big, beautiful ash tree, and live a few blocks from a large park (a couple of square miles) with hundreds of ash trees, so I worry just how long I'll get to keep my tree.
