Overgrowth of a Tree

A burl (or burr) is a bulky bump or wart like outgrowth on the trunk of a tree that occurs once the tree suffers some form of stress caused by an injury, virus or fungus. Just as in cancer, the tree cells increase frenziedly consequential in irregular huge bumps on the trunk. The world’s largest burl is on a  Sitka Spruce tree near Holberg on northern Vancouver Island.  The burl is about 6 meters in diameter and in height it also weighs an impressive 30 tones. This was divorced in the year 2005.
