Restoration ecology
Restoration ecology emerged as a separate field in ecology in the 1980s. It is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action. The term ""restoration ecology"" is therefore commonly used for the academic study of the process, whereas the term ""ecological restoration"" is commonly used for the actual project or process by restoration practitioners.
