Certainly, their food supply does need to be protected. From the research that's being done by scientists studying the southern resident killer whales, we now know their critical habitat. The scientists have defined an area that the whales rely on when they spend are in the Strait of Georgia. It could help them if we could provide better protection to some of that and try to reduce the impacts of some of the activities that are going on in that habitat that is essential to them.
Certainly they're going to be moving in and out of that, and that is part of what happens, but, but protecting elements of their habitat is really important.
We also have other species on land that move and we still use protected areas to protect them, species like bears and wolves that move great distances. We have seen that protected areas can make a big difference for those kinds of species as well.
