Grey Squirrel Welfare and Management Options in 2026

Grey squirrel management for conservation purposes involves significant welfare considerations, with ongoing research into more humane alternatives to lethal control.

Key Facts

Grey squirrels were introduced from North America and have spread across most of Great Britain
They out-compete red squirrels and spread squirrelpox virus to which reds are susceptible
Lethal trapping and shooting are current management tools with animal welfare implications
Oral immunocontraception using GonaCon bait is being trialled as a more humane alternative
Grey squirrels also cause significant damage to broadleaved woodland through bark stripping

Welfare Considerations

Grey squirrel management creates ethical tensions between the welfare of individual grey squirrels and the conservation benefit to red squirrels and woodland. Cage trapping and lethal despatch causes stress during confinement and acute welfare harm at killing. Bark stripping by grey squirrels causes slow death of trees, an indirect welfare issue for the broader ecosystem. Immunocontraception research offers a potential pathway to humane population management without lethal control.
