One thing that comes to mind if you're focusing specifically on the previous topic on aquatic invasives—and there's of course a committee we participate with Canada in—is that essentially with movement of invasives whether they are on a boat or whatever, as soon as they're in Canada there's no monitoring of them. So anything that comes along and moves interprovincially or inter-territorially is really a very difficult piece to monitor. I know the question of how you prevent the movement of invasives within Canada has often been raised.
It's a tough one for everybody to try to grapple with. Really either we need legislation, which each jurisdiction would prepare, or there could be more of a global piece developed. That's one area on the invasive side. I'll leave the other one that's more on the population management piece to Nathan.
