Isabella Tree is a British author, journalist, and environmentalist best known for her work in rewilding and nature conservation. She is the co-owner of the Knepp Estate in West Sussex, England, which she and her husband, Charlie Burrell, have transformed into a pioneering rewilding project. Through the reintroduction of grazing animals and the cessation of conventional farming, the Knepp Estate has become a thriving ecosystem, home to a wide variety of wildlife, including some of Britain’s rarest species. Tree’s book "Wilding" documents this journey and has become an influential text in the conservation movement, advocating for the restoration of natural processes and biodiversity.
