The grey wolf was hunted to extinction in Britain by the 18th century, and its potential return through rewilding is one of the most debated conservation topics, raising welfare questions spanning wolves, prey species, livestock, and landscapes.
Wolf rewilding welfare considerations are complex and multi-directional. Individual wolves introduced to Britain would face enormous territory requirements in a small, fragmented, and intensively used landscape. Livestock depredation would create welfare conflicts requiring robust compensation and deterrence programs. The ecological benefits for prey species, through population regulation and behavioural modification, represent welfare gains that must be weighed against immediate costs. The very long timescale of land use change needed makes meaningful wolf reintroduction in Britain a future-generation question.
