Fundamentals of Restoration Ecology
Removing cause of degradation or physical stress
Return ecosystem to pristine state (rarely accomplished)
Short and long-term monitoring after restoration (necessary)
Restoration
Manipulation of nature to recreate species composition and ecosystem processes to the state they were before humans interfered
Remediation
Process of cleaning chemical contamination from a polluted area by physical or biological methods to protect human and ecosystem health
EX: Cleaning polluted area
Some plants selective eliminate toxins from soil
Poplar
Mustard
Sunflowers
Bacteria
Rehabilitation
Bringing an area back to a useful state for human purposes rather than a truly natural state
EX: China’s Sloping Land Conversion Program
Reclamation
Techniques used to restore the shape, original contour and vegetation of a disturbed site

Attempts to construct a new biological community or infrastructure on a site so severely disturbed that there is virtually nothing to restore
