Invasive Species in Canada: Wild Pigs, Goldfish, and Bugs

In Canada, domestic pigs and European wild boars interbred, creating a resilient invasive species known as wild pigs, which have proliferated across the Prairie Provinces since the 1980s. These pigs thrive in diverse habitats, damaging wetlands and farmland, and preying on local wildlife. Their rapid expansion, fueled by low human density and a lack of natural predators, has led them to occupy over one million square kilometers. Experts caution that eradication efforts may be futile, emphasizing the need to understand their established presence.
