Along Yellowstone National Park's East Entrance Road, a resourceful combination of topsoil and on-site organic material has restored native vegetation, ground cover, a natural setting, and roadside habitats for birds and small mammals. When biologists from the Western Federal Lands Division of the Federal Highway Administration, in partnership with the National Park Service, revegetated the disturbed slopes along Yellowstone National Park's East Entrance Road, they didn't lose scarce topsoil to construction "cut and fill," and they didn't have to truck in soil supplements. They accomplished the revegetation by saving the construction-site topsoil, storing it in mounds just beyond construction limits, and later combining it with forest duff, boulders, and tree snags and trimmings to spread on the road's roughened slopes.
