The northern US states of Minnesota, North Dakota and Montana are taking steps to stop the invasion of so-called ‘super pigs’ from Canada. There, crosses have arisen between wild boars from Europe, which have good survivability, and large local pigs.
Ryan Brook, a professor at the University of Saskatchewan in Canada, calls it “ecological drama.” He calls ‘superpigs’ “one of the most invasive species in the world”.
Wild boars have not only the survival instincts of European breeds, but also the reproductive drive and size of Canadian pigs. This has made it impossible to control the number of pigs.
“Even if you kill 65 percent of the population every year, the species will continue to grow,” says Brooke AP News. He and other scientists estimate that at least 62,000 of these ‘super pigs’ now live in the wild.
Some animals are found within 17 miles of the Canadian border with the state of Minnesota. The US Department of Agriculture has increased the number of drone surveillance flights and inspections along the Canadian border.
Because of their size and hunger, ‘super pigs’ can cause more damage. Annually, wild boars cause nearly 2.3 billion euros in crop damage in the United States.
