Those saying it was just a tree are missing the point I feel. It's particular value was not that it was a tree, but in it's aesthetic appeal, and so the crime is more akin to vandalism of art works or landmarks. The Mona Lisa is just some paint on a canvas after all, Stonehenge is just a bunch of rocks, but no one would argue that their destruction would be treated in the same way as a ripping up an amateur's painting, or knocking over a dry stone wall.
