Feral"super pigs" in Canada could soon trample across the border and invade the northern U.S., a new study finds.
Super pigs may eventually cross the border into North and South Dakota, Montana and Minnesota, according to the study, which was published May 9 in the journal Biological Invasions. While the southern U.S. already has around 6.9 million feral hogs, much of the north remains feral pig-free thanks in part to intensive control efforts.
