Red Squirrel Conservation Welfare: In-Depth Guide

Key Welfare Considerations

• Red squirrels have declined to approximately 140,000 individuals in the UK, mainly in Scotland and a few refugia.
• Grey squirrel competition is the primary driver of red squirrel population collapse in England and Wales.
• Squirrelpox virus carried asymptomatically by grey squirrels causes fatal haemorrhagic disease in red squirrels.
• Squirrelpox welfare impacts include skin lesions, conjunctivitis, weight loss, and death within 2 weeks.
• Vaccination trials for squirrelpox in red squirrels show promise as a welfare and conservation intervention.
• Grey squirrel control through trapping and humane dispatch is essential to protect red squirrel welfare.
• Conservation translocations of red squirrels to predator-free islands provide welfare-safe refugia.
• Supplementary feeding stations specifically designed for red squirrels support welfare in marginal habitats.
• Coniferous forests provide better red squirrel welfare habitat than deciduous woodland (grey squirrel preferred).
• Genetic diversity is an important welfare consideration in small, isolated red squirrel populations.
• Road mortality is a significant welfare and population concern for fragmented red squirrel populations.
• Wildlife bridges over roads reduce red squirrel mortality and support population connectivity welfare.
• Captive assurance colonies maintain welfare-managed insurance populations against catastrophic red squirrel decline.
• Community engagement in red squirrel conservation increases monitoring capacity and human-wildlife welfare relationship.
• Red squirrel conservation represents an integration of individual welfare and population-level welfare outcomes.
