Mosses and lichens on trees are not uncommon. Varieties of lichens are many and they are all different.
Lichens are natural formations that settle only in clean ecological zones, where there is still a sufficient level of oxygen for life.
The tree is overgrown with lichens, when the process of its growth is inhibited and biological development slows down. The bark on the skeletal branches and trunk ceases to be updated, peel and then on the dead tissues appear lichens.
Today I will show you leaf and bushy lichens of gray color, which I photographed on the old trees in the Park. And in the next publication I will show photos of yellow-orange lichens.
