In evaluating and monitoring, again, I'll bring this back. It's very coordinated. It requires everyone to be involved because we can't be everywhere all the time. We're always looking for new technologies, things such as this environmental DNA where we can go out and sample the environment rather than requiring us to physically capture the organisms.
We look at the scale of the Great Lakes, the volume of water, and the amount of physical habitat. As for whether Ontario or Michigan or the U.S. Army Corps of Engineers is somehow going to be able to state unequivocally that the species is not in the system, I don't think any one agency can bear that responsibility.
Again, we work to understand where we're all at. We apply emerging technologies. We have coordinated workshops where Ontario ran a rapid response workshop on Asian carp and brought in jurisdictions that involve U.S. as well as federal partners to understand what we can do.
Again, I think that's really the best we can do, to work together and to keep our eyes open. The education/outreach side is key just to help people understand the seriousness of the threat.
