Wind, fire and frost can seriously damage or kill trees. Animals also wound them when they feed on bark tissues, and when they rub their bodies or antlers against tree trunks. Insects, like bark beetles can cause significant damage damage to woodlands and forests.
The extent of damage to trunks and the bark of trees varies considerably in relation to the nature of the ‘attack’. If the damage to the bark is severe and the vascular cambium is exposed then neither new water nor sugar conducting tissue can be formed. Damage to the (outer) cork cambium (phellogen) will limit the trees ability to form the outer tissues of the bark - which protect the tree. If the damage is restricted to the outermost bark layer then this will render the tree more susceptible to further damage (be it from herbivores or temperature extremes). Read more...
