You raise some very good points. I think right now we are in a place of learning from nature. As climate change is affecting our environments and shifting ecosystems, and in fact, as ecosystems are under pressure and there is less area for species perhaps to be in locations where they normally would have been, we have to start learning from species and from nature.
One of the things I'm encouraged about with Parks Canada is that I believe they are looking at some new models that they will be taking out and having a conversation with the public around the development of ecological corridors. Using a guideline developed at the IUCN, ecological corridors will be about what the ecological functions are that we find there are and how we protect them. It might not be strict protection, but it might be a more flexible tool to help us achieve some of our ecological objectives around species.
CWS at Environment Canada also has a responsibility for helping manage and protect endangered species. It might not use the tool of strict protection but other tools.
For all of us, these are unprecedented times as nature is shifting and trying to adapt. It will be important for all levels of government, and in fact, all of society to be continuing to learn in these very real, live experiments that we are seeing play out in our backyards.
I don't know the particulars of this specific case, but I would hope there could be an open dialogue with Parks Canada as they are in a learning mode and trying to bring new products to the public that can help achieve the goals around protecting endangered species, and in fact, growing habitat.
