Ecological Restoration

Ecological restoration is the applied scientific practice of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed, often as a result of human activity. This hands-on field within environmental science involves active interventions such as reforestation, the removal of invasive species, the reintroduction of native wildlife, and the restoration of natural hydrological patterns. The ultimate goal is to re-establish a self-sustaining ecosystem with improved health, integrity, and resilience, thereby enhancing biodiversity and restoring the vital services it provides to the environment and human communities.
