They have a number of positive impacts. We recently did some work, for example, on the ecosystem value of these places, and that could include things from flood mitigation to species protection, climate heat reduction and carbon storage in forests.
Our preliminary numbers are about 2.6 trillion per year for collection by Parks Canada places. It's an enormous number. Those are the big things, and we've done studies now to understand the carbon storage in all our places and the fluxes in the carbon. Protected areas, and especially, as recent studies have shown, managed protected areas contribute to biodiversity goals but also contribute to climate goals as well.
