Using one or more exotic species to achieve stability and productivity. That is, there is no attempt to restore any of the original biodiversity at the site.
David Lamb, 1994

Returning disturbed lands to a form and productivity that will be ecologically balanced, often in conformity with a predetermined reclamation plan.
USDA Forest Service, 1997

To recover productivity at a degraded site using mostly exotic tree species. The original biodiversity is not recovered although the protective function and many of the original ecological services may be re-established.
Gilmour, D.A. et al., 2000

Gain of land from the sea, or wetlands, or other water bodies, and restoration of productivity or use to lands that have been degraded by human activities or impaired by natural phenomena.
PEENRA website

To recover productivity (but little of the original biodiversity) at a degraded site. In time, the protective function and many of the original ecological services may be re-established. Reclamation is often done with exotic species but may also involve native species.
UNEP World Conservation Monitoring Center website

The process designed to adapt a natural ecosystem to serve a utilitarian human purpose. It may put a natural ecosystem to a new or altered use, most often using introduced plants. It is often used to refer to processes that replace native ecosystems and convert them to agricultural, mining or urban uses.
