Pine martens have contributed to red squirrel recovery in Ireland through their natural predation on grey squirrels, providing an ecological model for their potential role in Great Britain.
Pine marten welfare in Ireland demonstrates the benefits of legal protection and natural population recovery. Their ecological role in suppressing grey squirrel populations while benefiting red squirrels provides an example of how carnivore recovery can produce welfare co-benefits for other species. Translocation planning must incorporate welfare protocols for captured and released individuals.
