We don't have a gold standard for assigning an ecological end point. Alan is perfectly correct that Parks Canada led on the development and application of the idea of ecological integrity, and it has been picked up by many countries. I don't think it's really all that different than the IUCN definition of conservation. I think the most important thing to understand is that it's not a binary condition. It's not a condition that you either have or you don't. It's a sliding scale.
We all agree that the Rouge isn't pristine, but it has real ecological value now. In terms of ecological integrity, I think that the management goal is to maintain what we have, and where we have opportunities to make it better, to restore it. I think that the state of park reporting we set up looks at success or failure based upon relativity, where we are now. We don't want to decline. I think ecological integrity can easily account for that kind of sliding scale. In fact, it does so right now in the range of national parks.
Parks Canada runs a park in Point Pelee, a park in the Thousand Islands, and a park in P.E.I. that is a coastal strip, all under the rubric of ecological integrity. I think it does so quite successfully because it uses relativity in its management, and I think it can equally apply here. Ecological integrity is used, as I mentioned, by management agencies. It can be used for forest companies.
If you look at the case of Pukaskwa and the power line, that clearly takes away ecological integrity from its current state. I think the answer is in relativity.
