Habitat restoration is the process of actively restoring or rehabilitating natural ecosystems that have been degraded, damaged, or destroyed. This can include restoring wetlands, forests, grasslands, rivers, or other habitats that have been altered by human activities such as development, agriculture, or habitat fragmentation. Habitat restoration aims to improve biodiversity, promote ecosystem resilience, and enhance ecosystem services such as water purification, carbon sequestration, and wildlife habitat. Techniques used in habitat restoration may include re-planting native vegetation, removing invasive species, restoring hydrology, and reintroducing native wildlife species. Habitat restoration is often used in conservation efforts to address the loss of biodiversity and ecosystem functions caused by human activities.
