Sure.
There's no question that the prey-predator relationships are a factor, but I think one of the key things, as I mentioned earlier, is that we're creating in some cases, particularly near protected areas already.... As you rightfully pointed out, the range of woodland caribou is quite large, so even a national park in a lot of cases can't contain the range of a particular woodland caribou or a particular herd.
What we have to do is think about what kinds of impacts we're actually having on the habitat of those caribou that are actually influencing the prey-predator relationship. That is where the creation of roads and where the creation of access ways, in fact, has become one of the bigger pieces of the puzzle.
Predator control has its place in certain circumstances, but the bigger factor, when we look at habitat, is more often how that habitat is fractured and how that creates an opportunity for predators more than it does protect the prey.
