Invasive Grey Squirrel Welfare

Grey squirrel control for red squirrel conservation raises welfare challenges; contraceptive and humane methods are being developed.

Key Facts

Grey squirrels were introduced from North America to Britain in the 1870s
They displace native red squirrels through competition and squirrelpox transmission
Control methods include trapping and shooting which cause variable welfare impacts
Oral contraceptive baits are in advanced development as a humane alternative
Squirrel immunocontraception would enable population reduction without lethal control

Welfare Considerations

Grey squirrel control presents a difficult welfare trade-off between the welfare of individual grey squirrels and the conservation interests of native red squirrels. Lethal control by trapping and shooting, when conducted to high welfare standards, minimises individual suffering. Immunocontraception, when available, will offer a welfare-superior alternative that addresses population management without killing individuals.
