Feral hogs, which can survive the winter, are increasing in Alberta, Manitoba and Saskatchewan, causing significant damage along the way.
These wild animals have developed a resistance to bad weather over the years while becoming larger and more difficult to catch, reports the New York Post.
According to Ryan Brook, a professor at the University of Saskatchewan, wild boars are “the most invasive animal on the planet” and “an ecological disaster.”
People have reported seeing a wild boar 62,000 times in recent years.
Mr. Brook explains that this problem began in the 1980s when Canadian breeders were encouraged to raise wild boars.
Due to the decline in demand for this species, many farmers have simply released their animals into the wild.
These would then have multiplied among each other until their population became problematic.
These beasts can easily and quickly devastate fields and kill other animals.
Hunting these species would also be very difficult as they are difficult to reach and quickly habituate to nocturnal movements, making the task even more difficult for hunters.
Ryan Brook says feral hog eradication has become “impossible” in Saskatchewan and Manitoba.
The state of North Dakota is taking the situation seriously as specimens have been spotted about 25 kilometers north of the Canadian border.
The Ministry of Agriculture is expected to publish a report on the issue in February.
Drones are already being used to spot the animals before they become too much of a problem south of the border.
