For many animals, including caribou and musk oxen, lichens are an important food source. Lichens are also important in the weathering process of rocks. They grow on bare rock and release acids as part of their metabolism. The acids help break down the rock and as bits of rock accumulate and lichens die and decay, soil is formed. They are important in the primary succesion.They don't need to survive with soil.
