Restoration techniques refer to methods used to repair, preserve, or enhance the condition of various objects, structures, or ecosystems. These techniques can apply to art, historical buildings, or natural environments, aiming to return them to their original state or improve their longevity. Common methods include cleaning, repairing, and using protective coatings. In the context of art restoration, professionals often use specialized tools and materials to fix damage while maintaining the artwork's integrity. For ecosystem restoration, techniques may involve replanting native species, removing invasive plants, and restoring natural water flow to revive habitats and promote biodiversity.
