Snow goose populations have exploded dramatically due to agricultural food subsidies and reduced hunting, causing severe damage to Arctic tundra and saltmarsh ecosystems. Managing overabundance creates welfare trade-offs at enormous scale.
Snow goose welfare involves a genuine tension between individual and ecosystem perspectives. Individual geese killed in management hunts experience acute welfare harms — wounding, stress, and death. But the ecosystem destruction caused by overabundant colonies causes long-term welfare harm to the many thousands of individual birds — including snow geese themselves — that depend on healthy Arctic vegetation. Eat-outs reduce nesting success, force family dispersal, and eliminate cover used by chicks during brooding. The welfare of dozens of other tundra nesting species is also affected by habitat loss. From a utilitarian welfare perspective, the management calculus often favours reducing populations to restore habitat, but only if hunting methods minimise wounding rates. Improved shotgun ammunition, hunter skill requirements, and retrieval standards reduce wounding. Non-lethal population management through egg oiling and nest disturbance reduces summer reproduction but requires scale beyond feasible implementation.
