Knepp Estate Rewilding, United Kingdom

Knepp Estate Rewilding transformed 1,400 hectares of former intensive farmland in Sussex into a biodiversity hotspot, with turtle dove populations increasing by 1,200% and purple emperor butterflies colonizing the site in 2022. The project's free-roaming cattle, pigs, and ponies have created dynamic habitats, boosting soil organic matter by 15% compared to conventional farmland. However, neighboring farmers resent the spread of weeds like ragwort and thistles onto their land, which resulted in a 2023 legal dispute costing £30,000 in compensation.
