Large Herbivore Rewilding and Ecosystem Welfare

Reintroducing large herbivores creates grazing dynamics that benefit dozens of species simultaneously.

Key Facts

Feral cattle, horses, bison, and deer are used as rewilding herbivores across Europe
Konik horses and Exmoor ponies at Wicken Fen and Knepp have transformed vegetation structure
Large herbivore grazing creates heterogeneous habitats — short and long sward, bare soil, scrub — essential for many species
Rewilded herbivores require less veterinary intervention than farmed equivalents
Predator absence means rewilded herbivore populations require periodic management to prevent overabundance

Welfare Considerations

Rewilded large herbivores experience welfare benefits from freedom to express natural behaviours: group foraging, seasonal movement, and social structures determined by preference rather than management convenience. At the ecosystem level, their grazing creates the mosaic habitats that support dozens of invertebrate, bird, and mammal species with their own welfare needs. The welfare of rewilded herbivores and the species they support are linked — restoring natural grazing dynamics improves welfare conditions across communities simultaneously.
