Super Feral Pigs: The Threat of Invasive Species Spreading from Canada to the US

Scientists have recently conducted research that has raised concerns about the potential threat of super feral pigs in Canada spreading into the northern United States. These pigs, a mix of domestic pigs and boars that were introduced to Canada in the late 1980s, have been thriving in Canadian prairies despite harsh winter conditions.

According to Ryan Brook, a professor at the University of Saskatchewan, these super feral pigs are highly mobile and have a high reproductive rate. Their ability to tolerate cold temperatures has earned them the nickname of “super pigs”. With their potential to cause significant damage to agricultural production and ecosystems, authorities are concerned about the spread of feral pigs into the northern United States.

To track the movement of feral pigs in Canada, researchers fitted GPS collars on a group of pigs to monitor their movements over a 13-month period. The data collected showed that feral pigs are likely to target habitats such as swamps, deciduous forests, and crop fields that provide food and shelter. With these preferred habitats prevalent in the boreal grasslands and along borders, the risk of the pigs crossing into the United States is a real concern.

In order to mitigate the potential spread of feral pigs into the northern United States, researchers suggest implementing measures such as planting low-crop crops, erecting fences, and setting traps to deter the pigs from accessing their preferred habitats. With some feral pig populations in Manitoba, Canada located just a few days’ travel from the US border, proactive measures need to be taken to prevent further spread and damage caused by these invasive species.
