Lichen


During my inspection of the fruit trees I found one of the pears had some patches of lichen. Lichen won't hurt the tree but it does signify that the tree is declining. This particular one is getting old and may indeed be reaching its end. I carefully removed the dead branches and gave it an extra dose of fertilizer as well. Hopefully this will help it improve.
A lichen is actually two organisms that are living together in a symbiotic relationship. One is a fungus and the other an algae. The algae is the one responsible for providing energy for their survival and the fungus provides a home. Lichen can be found anywhere. They live in areas that have good air quality. Some lichens are even found on the Arctic Tundra.
