Certainly enforcement is a key element in the long-term management of a marine protected area. There are many elements to that, and there are different ways to do it. I know that in Australia they use overflights, and there are a lot of electronic tools that fishing boats now need to carry in order to ensure that they're not going inside marine protected areas. As the technology improves, I think there are a number of ways to ensure that the rules around the marine protected areas are enforced.
