Verified by Experts

The lichens are the pioneer species that invade a bare area such as the rocks. The lichens secrete acids to dissolve rock and help in soil formation. The lichens are followed by bryophytes which are able to hold the soil together. The bryophytes are replaced by larger plants and in the end a stable climax forest comminuty is formed. The succession of plants turns xeric conditions into mesic.
