Ecological restoration refers to the principle of restoring something, for example a landscape or an ecosystem, based on ecological principles, processes or methods. An example of this can be the restoration of an deforested area by allowing forest to re-emerge through various forest succession stages rather than planting a mixture of the plant species that used to be present before the area was deforested. Ecological restoration can take place as part of a rewilding strategy. Rewilding strategies, however, tend to come with more specific ideas about which species should be present or (re)introduced and a clear overall vision about particular processes in the ecosystem that should be encouraged.
