When a new site is created or rehabilitated in compensation for a site damaged or destroyed elsewhere

Nonpoint source pollution
Pollution coming from a general area rather than a specific site
Biocultural restoration
Restoring lost ecological knowledge to people to give them an appreciation of the natural world
Economic development
Economic activity focused on improvements in efficiency and organization but not necessarily on increases in resource consumption

Limited development/ Conservation development
Compromise involving a landowner, a property developer, and a conservation organization that combines some development with protection of the remaining land
Conservation leasing
Providing payments to private landowners who actively manage their land for biodiversity protection
Conservation banking
A system involving developers paying landowners for the preservation of an endangered species or protected habitat type (or even restoration of a degraded habitat) to compensate for a species or habitat that is destroyed elsewhere
