The Canada Goose, a danger to ecosystems?


However, their number has increased dramatically in recent decades, so that we now speak of an unprecedented increase.

Large-scale grain production and urbanization have increased the available food resources while decreasing the risks associated with predators. Their reproduction has therefore accelerated, and the young goslings are multiplying at great speed. Formerly limited to certain portions of southern Canada, Canada geese have been able to extend their range considerably in recent decades.

Such growth now poses new challenges. It would effectively limit the sustainability of salmon and other species that live in the Fraser River, according to a young researcher from the University of British Columbia. Indeed, sedge, a plant prized by geese, is also essential for the migration of young salmon.

The Canada Goose is causing headaches for municipalities across the country as well. As each bird can produce up to one kilogram of excrement per day, sanitary management is essential in public places. Parks, for example, are particularly hospitable due to the presence of large expanses of grass and the virtual absence of predators. The city of Montreal is also trying to limit the inconvenience for citizens, particularly in the borough of Lachine.

Same story for the city of Longueuil and for many other communities.

The total number of geese is currently estimated at seven million across the country, according to the Government of Canada.
