Restoration involves actively working to bring something back to a previous condition, often because it has suffered injury or its integrity has degraded over time. Many things—artwork, architectural structures, or political institutions—can be the subject of restoration efforts.

Ecosystem Restoration

Ecosystem restoration entails returning an ecosystem to its previous healthy state. Humankind has historically disrupted ecosystems by logging, clearing land for agricultural purposes, and altering water levels and flows by draining swamps and constructing dams and dikes. There has been a recent increased appreciation for the “free services” that ecosystems provide, with a resulting increase in laws facilitating restoration. An early realization involved lost diversity through native prairie destruction. The first major prairie restoration was in 1934 at University of Wisconsin–Madison's arboretum.
