As I said, as these pinniped populations have built up in B.C., we've seen the standard mammalian density dependence in the survival rates of juvenile animals. They've dropped down and so on. However, we're also seeing a recent decline in the abundance of harbour seals. That's most likely associated with the continued growth in the transient killer whale population. Mother transient killer whales train their juveniles to hunt for mammals by taking them hunting for seal pups close to the shoreline. Other times they'd feed further offshore.
We'll see these continued changes going on. As said before, we can monitor them and we can respond to them. We've tried to develop computer simulation models that look at the whole ecosystem and all the possible interactions among multiple species. There are up to 60 different species of creatures at once in these models. The models do whatever you'd like them to do. There are just too many uncertainties that we will never be able to resolve by studying things piecewise in the field. We'll have to continue to manage adaptively into the future.
