The best definition from a protected areas perspective—and there's much more to habitat conservation than protected areas. There is an international classification system adopted by the International Union for the Conservation of Nature. I'm not going to go into the details. There are six different categories for protected areas. The tracking that we do in Environment Canada is something called the conservation areas reporting and tracking system. Working with our provincial colleagues, we use that categorization scheme.
I mentioned in my remarks that the Canadian Council on Ecological Areas is doing more work on how to define other area-based conservation measures, but there will be conserved lands and conserved habitat beyond those definitions that will be important. There isn't a definition for those lands beyond the categories that were just talked about, but that shouldn't diminish in anyone's mind the importance of those lands for biodiversity and the other outcomes we've talked about.
