Restoration is the process of actively or passively assisting the recovery of an ecosystem towards or to good condition, of a habitat type to the highest level of condition attainable and to its favourable reference area, of a habitat of a species to a sufficient quality and quantity, or of species populations to satisfactory levels, as a means of conserving or enhancing biodiversity and ecosystem resilience. Measures can include enhancing degraded soil and agricultural land with natural features like hedgerows and trees, restoring monoculture forest plantations with mixed native woodland, greening up cities, buildings and infrastructure, replanting seagrasses on the seabed, reversing human-induced pressures such as pollution and excessive use of pesticides.
