I didn't come prepped with those numbers. The European gypsy moth established in Ontario has caused major economic damage, which is why the B.C. government's fighting hard against it. In comparison, the European and the Asian gypsy moths—and remember on the back door is the pink gypsy moth also—target a lot of the economic tree species, so they will have the biggest impact. What's different about those species versus things like spruce budworm or mountain pine beetle is that, historically, in a well-managed forest, they wouldn't have as big a high cycle as the one we're hitting right now. When the European gypsy moth, or whatever, comes in, it doesn't have any natural predators, so that's why we're always concerned about it. It's not the next mountain pine beetle of the west.
