Invasive wild pigs continue to be a concern across the Prairies.
Dr. Ryan Brook, with the University of Saskatchewan, spoke on the issue last week at Manitoba Pork's AGM.
"Anytime you have wild pigs, their potential to explode and become out of control is very, very high. They have huge impacts on the ag sector and the environmental sector, even public health. We need to be very concerned. The numbers are relatively limited across most of Manitoba. There is a high concentration in the Spruce Woods area that's particularly important and they can function as what we call a stronghold. We're seeing this, pigs are dispersing out there on a regular basis and spreading and so there is a real concern for sure."
Brook says Saskatchewan has more than of half of all the wild pigs found across Canada.
"Especially in east/central Saskatchewan, there's one major hotspot that we know has more wild pigs than rest of Canada combined," he noted. "The problem for Manitoba is that hotspot is literally right on the Manitoba border. Manitoba is doing things and moving this forward and talking about it...but Manitoba also has to recognize that pigs can move in from Saskatchewan and so we need to all be rowing in the same direction and coordinating our efforts to make sure that Manitoba is successful inside the province but also being good neighbours as well."
The reason that wild pigs are so hard to control, according to Brook, is that they have a high reproductive rate, they eat almost anything, and are highly elusive. He adds diseases such as African swine fever is one reason the issue is gaining more traction.
In terms of control measures, Brook believes the best approach is to have lots of tools in the toolbox and to use them all. He says hunting is not one of the solutions as the success rate is amazingly low and it tends to spread the pigs around.
"You can either have sport hunting of pigs or you can have eradication, pick one. Right now Manitoba is effectively open season. I think we're going to need to have a serious conversation about changing that if we want to have success."
