Well, in some cases the management of fisheries has been under agreement to the inland provinces, but the protection of habitat is not. It's completely under federal jurisdiction at this point. What the future is, I don't know. I think there's some promise there. The problem at least has been recognized and the minister has referred to it.
My question is more of a theoretical one. Can a biological invasion also be a natural phenomenon? Is it accurate to say that there would be non-native invasions of even harmful species if there were no human interaction with the ecosystem? In other words, does it happen naturally as well?
