Comment: Management key to zebra mussel challenge

This invasive species is here to stay so we need to limit the damage

You could almost set your watch by it. Since 2013, when zebra mussels were first detected in Lake Winnipeg, new sightings of the invasive species in our lakes and on our shorelines have become a regular occurrence. And while the ubiquitous videos of their shells collecting on the shores of Lake Winnipeg that we have

Invasive species remains threat to bees, honey producers

Blaine, Wash. | Reuters — The first Asian giant hornet nest of the year has been found in Washington state, and plans are being developed to eradicate it, likely next week, the state’s agriculture department said on Thursday. The so-called stinging “murder hornets,” the world’s largest hornets, can grow to five centimetres in length and

We need to move beyond passive efforts, such as unrestricted hunting, that have been shown to disperse wild pigs and make the problem worse. – Cam Dahl

Comment: Wild pigs an alien invasion

It’s time for co-ordinated, targeted eradication efforts on wild pigs

We have been invaded by aliens. No, not green creatures from Area 51, but by plants and animals that don’t belong here. Take, for example, the common dandelion, which is not native to North America. European settlers brought dandelions here in the mid-1600s to enhance their gardens. Zebra mussels are another example; they are not

Many of these invasive species are mistaken for

Pig fighters without borders

An international working group hopes to make the fight against wild pigs a consistent one

The fight against wild pigs will have a newly united front in Western Canada and the western United States, should recommendations published late last year by an international working group get their way. Manitoba is among the provinces and states to throw its weight behind the body, which launched last year in an effort to

Some areas of Western Canada might already be past the point where “pig free” is even possible, says a University of Saskatchewan researcher.

Losing the war with wild boar

Forget eradication. For some parts of Manitoba it’s now a containment game

It’s time to up our efforts in the battle against wild pigs, according to a leading voice in the field. Ryan Brook of the University of Saskatchewan has spent years studying the rise of the invasive species in Western Canada, and has also spent years raising the alarm. He has watched as sounders — the
