I'll speak from experience. For example, one of the natural processes that has usually been used, in which Parks Canada is an international leader, is prescribed burns, for example, for ecological reasons and also in terms of fire management.
What we did in Parks Canada and what we've been doing for several decades is manage those responsibly. That's the type of natural processes that we would manage, but always considering the local reality. There are places where we've done a lot of burns historically, in Banff for example, and managed those. There are other places such as Grasslands National Park where we've been a lot more conservative in our approach when we were doing it. I say we were doing it, but I think natural processes are those types of things. The use of fire is one example, but again, with a responsible approach and a local engagement approach.
