How to treat lichens in a tree?

Do lichens harm trees?
Lichens on tree bark are harmless to the tree. Rhizines (similar to roots) allow them to attach to, but not deeply into the bark, thus not harming the tree. Many people think that lichens harm the tree when a tree becomes sick. This is impossible, and most likely the lichen was probably there long before the tree became sick.
