Wild Snow Goose Population Boom and Habitat Destruction

The dramatic overabundance of snow geese is destroying Arctic and subarctic coastal habitats, causing a cascading wildlife welfare crisis.

Key Facts

Light goose populations (snow geese and Ross geese) have increased approximately 300-500% since the 1970s
Mid-continent snow goose population exceeds 15 million birds, far above what Arctic breeding habitats can sustain
Overgrazing by geese causes 'eat-outs' - complete destruction of coastal marsh vegetation through roots
Eat-outs affect thousands of hectares per year in James Bay, Hudson Bay, and Arctic tundra
Once marshes are destroyed, recovery takes decades and reduced biodiversity affects hundreds of other species
Conservation order hunting regulations in the US and Canada now allow expanded hunting seasons and methods to reduce populations
The overabundance is partly attributed to agriculture providing abundant wintering food in the southern US

Welfare Considerations

Habitats destroyed by snow goose overgrazing no longer support the shorebirds, wading birds, and invertebrates that depend on coastal marsh vegetation. Individual animals that lose nesting and foraging habitat suffer nutritional stress and reproductive failure. The welfare of the many species that depend on intact Arctic marshes must be weighed against the welfare of individual geese in management decisions.

What You Can Do

Support conservation order hunting as a necessary population management tool for snow geese
Learn about the ecological connections between snow goose overabundance and broader Arctic wildlife welfare
Donate to Arctic marsh monitoring programs that track eat-out progression and recovery
Advocate for winter habitat management in the southern US that reduces the energy subsidy driving snow goose population growth
Follow long-term population modeling research that guides adaptive management
