I will just point out, because you used the term "invasive”, that the mountain pine beetle is a native species. It's native to Canada and to this area but it is behaving a bit like an invasive species in how it's now shifting into the Jack pine stands in Alberta. Those trees have not had an evolutionary history with the beetle and don't have the same kinds of defences.
In terms of answering your question about other jurisdictions, I'll point to the United States. They're also dealing with pine beetles, certainly in Colorado, Idaho, Oregon and elsewhere. The situation is a little different in the States. Colorado is doing a lot to manage the beetles in their stands. Their forests are a little different from ours. There's a lot more ponderosa pine, for example, down in Colorado. They have slightly different management strategies but on the whole they're working on it as well.
I couldn't give you any numbers to quantify what this might look like but there is a risk that logs, say from Colorado, might be shipped across the border into Canada. If those logs haven't been treated by having the bark removed and/or heat-treated, these beetles could be brought in from other jurisdictions.
It would then be important to make sure that any such shipments are checked to ensure that they're following proper protocols.
