Absolutely. There are a number of components, but clearly prey availability is a key one for southern resident killer whales, and their preferred food is the chinook.
We're continuing to identify and protect new areas of habitat necessary for their survival. Protecting the habitat, protecting the foraging areas, reducing noise and all of those sorts of things help with their foraging activity.
I believe also that there is a component in there to enhance the hatchery production. That results in a focus on a specific type of chinook salmon from the Fraser River, and it would result in a return of about 30,000 additional chinook salmon. That is a very significant increase, especially in that subcomponent of the chinook population.
