I have just one last comment, not a question necessarily.
To go back to one of the earlier points that I made, we have to be very careful to distinguish between harmful invasives and some invasives that have settled in and are actually helping things out. Dr. Quinney is very familiar with the introduction of the wild turkey to Ontario, a new species. Again, where I come from, Lake Winnipeg, the smelt invaded from the States via a whole bunch of avenues and has now become a very important forage fish for the economically important walleye there.
So I think it's critical for us to focus on those species that actually are causing human and ecosystem damage.
Thank you.
