Pleistocene rewilding is the conservation and ecosystem management practice of reintroducing Pleistocene megafauna or their close ecological equivalents to areas within their former ranges. It is a form of the conservation practice of rewilding.[1]
Towards the end of the Pleistocene era, most terrestrial megafauna on earth went extinct, in what has been referred to as the Quaternary extinction event.[2] With the loss of large herbivores and predator species, niches important for ecosystem functioning were left unoccupied.[3] Many megafauna are ecosystem engineers, shaping ecosystems at the landscape scale, and the species lost in the quaternary extinction event had a disproportionately large ecological impact. [4][5]
Proponents of Pleistocene rewilding argue that it could restore ecosystem function and improve resilience. In some systems, it has also been advocated for as a potential method of climate change mitigation, thus functioning as a form of bio-geoengineering.
