The trunk is very thick, there is a lot of water contained in the wood itself, and pitch, which is very flammable, is not contained in the tree. The bark lacks the resin found in pine, fir, and spruce trees, and the sap is largely water which adds to the fire resistance. The redwood tree is particularly resistant to fires which remain primarily along the ground.<BR/><BR/>Despite its resistance, however, repeated fires may reach the heartwood through cracks in the bark. The tree may be "hollowed out"as the damaged heartwood decays, while the outside, growing layers remain intact."<BR/><BR/>What is surprising to many visitors, however, is the degree to which an enormous redwood tree can survive fire damage which hollows out and weakens the wood at the base of the tree. Fungi can invade the damaged wood and cause it to rot, eventually forming a cavernous hollow area. A "chimney tree" is a redwood whose entire interior was burned out by fire. Trees with hollows this large, which may be the result of 50-100 fires, are often also called "goosepen" trees as they made convenient places to keep domestic animals such as geese. The may also serve as shelter or residences for black bears and colonies of bats."Karen Annehttps://www.blogger.com/profile/13306986336556283751noreply@blogger.com
