Conservation recovery programs for pine martens and the welfare of reintroduced individuals.
Pine marten reintroduction welfare encompasses the individual welfare costs of translocation and the population-level welfare benefits of range expansion and recovery. Translocation imposes acute stress on captured individuals including the novel environment of captive holding, transport, and release into unfamiliar territory. Post-release monitoring through GPS tracking allows welfare assessment during the critical establishment period, identifying individuals that are failing to settle and requiring intervention. The cascade benefit to red squirrel welfare through grey squirrel suppression represents an ecological welfare dividend that extends the welfare significance of pine marten recovery beyond the individual species.
