Absolutely, and I hope I didn't suggest that was not the case within my general comments.
In fact your question is very pertinent. Right now I'm involved in a study of coyotes in Cape Breton Highlands National Park, where of course, very unfortunately, there was a death a couple of years ago because of a coyote. The park has very cleverly, I think, tried to be very proactive in getting a study under way. I have a student up there right now looking at this issue, where they're taking a very holistic approach. But a large component of the approach is looking at human behaviour. Indeed, in all of North America, in recorded history, there have only been two cases where coyotes have killed people: one in California, and one, unfortunately, here in Nova Scotia.
Absolutely, this is a very serious issue. But again, I come back to how wildlife management is people management. Indeed, national parks are unique in the sense that people arrive there as visitors wanting to see nature, wanting to get close to wildlife. Unfortunately, many people, as it turns out, through interviews that a researcher from Newfoundland has been doing, feed the coyotes. If you feed any animal.... Red squirrels, if you feed them, will attack you if you don't feed them. So there's a huge component of needing to educate the public in order to understand these issues.
They are predators, and humans can certainly be food to, as you mentioned, wolves and cougars in B.C. Yes, there is that aspect to it, but this is a small component of wildlife management, of conservation, that needs to be addressed.
