Wild boar are ecosystem engineers whose rooting behaviour creates habitats that benefit numerous other species, making their welfare and conservation of broader ecological significance.
Wild boar welfare and habitat welfare are inseparable in rewilding contexts. Boar that can roam large territories, form stable family groups of sows and young, and forage freely create ecological benefits across entire woodland systems. Their rooting behaviour — the same behaviour that makes them agricultural pests — is also the mechanism through which they create the microhabitat complexity that supports hundreds of other species. Management approaches that allow free-ranging boar in appropriate landscapes while managing conflict at the agricultural interface create conditions for both boar welfare and ecosystem welfare simultaneously. The ecological engineering function of boar is a reminder that individual animal welfare and ecosystem welfare are often served by the same management decisions.
