Red squirrels persist in UK refuge sites under intensive conservation management, with welfare depending on squirrelpox prevention and habitat quality.
Individual red squirrel welfare at refuge sites is threatened primarily by squirrelpox exposure. The disease causes facial swelling, scabbing, and a slow death over 15-21 days. Winter food shortage in poor mast years causes starvation of juveniles and subordinate animals. Intensive grey squirrel trapping at refuge sites reduces squirrelpox exposure but requires ongoing effort. Welfare-informed conservation includes rapid euthanasia of pox-affected animals to prevent prolonged suffering, supplementary feeding during food scarcity, and vaccination development.
