There are two things: Native species such as mountain pine beetle, such as budworm, are native to some places in Canada. Their range has expanded. It is totally linked with climate change, with wind patterns, etc. I don't believe there is a goal in Canada to eradicate any species. That's not in keeping with our biodiversity thinking. We want to maintain them, but what happens with native species like this is they hit a peak cycle and they will really explode. Part of that is linked to forest management, and why they have exploded may be due to lack of forest fires or too many forest fires or whatever. I come from a world where there weren't enough fires and now we have them in spades. Those are our tools. When you're hitting native species and they have economic and biodiversity impacts, like the two you've mentioned, it's more of a control issue. How can you reduce their impact? You're not trying to eradicate those. With foreign ones, you're trying to prevent them and then eradicate them, so you don't have the same economic impact.
