What makes a horse truly wild? Isabella discovers the fine line that divides domesticated from wild horses with Rina Quinlan, Knepp safari guide, founder of the Large Herbivore Working Group and queen of the equines. Understanding the social dynamics of Knepp’s Exmoor pony herds has changed the way Rina manages her own horses and livery – insights she hopes to communicate to other horse owners. But keeping the Exmoors wild is challenging, too – their wellbeing and the dynamics of the rewilding project depend on it. Again, it’s people’s behaviour that needs to change. 

Isabella Tree is co-founder of Knepp rewilding project. Her latest book ‘White Stork – restoring a missing bird to Britain’ will be published on 1 April 2027.
