There are some non-parasitic organisms called Lichens, that live on the bark of trees. They can also appear on rocks and fences. Due to being non-parasitic, they do not harm what they grow on. However, quite often people blame them for the reason why their plants are dying, even though they are simply weakened naturally. Normally lichens like their homes to be damp, although they can grow elsewhere. Unfortunately if lichens grow on the ground (such as on paths and pavements) it can become slippery.
Lichens can not be removed with chemicals and taking it off the tree would likely cause more issues to the bark. However it can be helped by making sure the tree is pruned correctly and excess vegetation is removed. If the condition around the plant is good then it has a better chance of getting stronger. For instance, if the soil is in good condition, then the tree has a better chance of thriving. If the lichen has appeared on a hard surface, it can be removed with a wire brush or a surface cleaner.
