I think with the species that you mentioned, the peregrine falcon and the bald eagle, you need to look at what the cause of the original endangerment was. In the case of both of those species it was chemical contamination, DDT principally, that caused eggshell thinning and less reproductive success. As that's disappeared out of the environment because we've banned the chemical, the birds have become more abundant, and as a result they've been moved down the endangered list. I think that's a success story, where we recognized the problem, we did something about it, and now the situation has improved.
With the situation with woodland caribou, what we've noticed over time is the range of that species has moved northward because of their inability to adapt to the type of industrial activity that we do in managed forests. As a result, it's moved up the attention list and now it's been listed as a threatened species under both the federal act and the provincial act in Ontario, and in many other provinces as well. The emerging consensus is that we need to do something different about how we manage forests in order to conserve that species.
I think what you'll see is the same kind of trajectory. If in twenty years, after we make some changes to the system and the woodland caribou is doing better, and it's reoccupying range it was lost from, we'll take whatever methodology that's been developed and we'll move it throughout the forest so that species can persist.
I think we've learned something from the way we've dealt with some of the species that became endangered twenty years ago and we've made the changes necessary and now we're recovering some of those. And I think we need to apply the same kind of experience to something like the woodland caribou.
