Document Summary
Rehabilitation - repairing ecosystems function, but not to original condition. Reintroduction - transplanting organisms from an external source to a site where they have been previously reduced/eliminated. Remediation - using chemical, physical or biological methods to remove pollution while causing as little disruption as possible. Reclamation - employs stronger, more extreme techniques to clean up severe pollution or create a newly functioning ecosystem on a seriously degraded or barren site. War-torn rwanda began a country-wide forest restoration in 2001. 85% of the population still subsists on farms on degraded land. Restoration of forest conserves the national wildlife, including the mountain gorilla. Tourists visit these areas for wildlife viewing. Nc examples: longleaf pine, piedmont prairies, pine ridges in mountains, forest structure. Food and habitat for a variety of species. Bioremediation - using living organisms to remove toxins. Some plants can selectively eliminate toxins from soils. Decontaminated urban fields ( brown fields ) can become valuable real estate.
