Abstract
Man has been a chief factor disturbing the natural forces, which maintain the plant cover of the earth's surface. He has cut down or burned much of the virgin timber and broken the sod of prairies and plains in his struggle for food, clothing, and shelter. Early settlers of the front range of the Colorado Rockies turned to cultivated crops to increase the food supply. Many acres of foothill valley land were cleared and broken out for crop production. Cultivation proved unprofitable after a time and now many areas have been abandoned to the natural forces influencing the region. Nature has accepted the responsibility and is doing her very best to heal the man made scars and cover the old fields with a blanket of permanent vegetation.
