There are some very interesting models, but not specifically related to what you just referred to. One that I'm particularly aware of is in the United States, and this goes back to the question about how to engage urban Canadians in nature.
In Chicago they started by making urban people aware of birds in their natural areas within the city. That evolved to become a nature initiative for all of Chicago. It involved 30 or 40 stakeholders from the government, the private sector, etc. It was phenomenally successful. I think there are huge opportunities for all of our major urban areas to appropriate some of that experience.
