Where did the mosses and lichens are found?
tundra vegetation
Mosses and lichens are mostly found in tundra vegetation. The climatic condition of tundra , which does not exceed 10˚C in the summer season, makes it difficult for plants to survive, thus lichens are of great importance. This vegetation is found in the polar areas of Europe, Asia and North America.
