Yes, exactly. That is one of the reasons why it's critically important to do regular monitoring of MPAs. When we set up these MPAs, we had specific conservation objectives, and yet, as you say, we're living in a changing world. The oceans are changing and species ranges are moving mainly north as the climate warms.
We need to be monitoring this to be make sure our boundaries are in the right place so that the species we want to protect remain within the boundaries. That's a real challenge. It's not going to happen in a dramatic “one year to the next” fashion, but it is something that we need to be keeping track of so we can make decisions in the future when we still have within the boundaries of our MPAs the species we intend to conserve.
