In the past two years our firm has handled two death resulting from falling trees. In both instances there was a failure to inspect and remove the tree after telltale signs of rot and decay existed. Many times the dangerousness of the tree can only be detected by professional arborists. To avoid liability, and more importantly injury to others, be proactive in evaluating the large trees on your property. These trees can weigh more than 60 tons and easily can crush a car or almost anything else in its way.
