I just returned from a sailing trip to Gwaii Hannas National Park in Haida Gwaii off British Columbia's northern coast. It is interesting to see how the Haida people are co-managing the National Park with Parks Canada. I had the chance to talk to some of the Haida Watchmen at the heritage sites; those times were some of the best parts of the visit. Hearing about the Haida culture from someone who is living it makes it much more powerful than getting it second-hand.
I found quite a contrast between how we (non-Haida) and the Haida described the sites. We would call them abandoned but the Haida don't. They regard them as part of their living culture. If you look at this video you will see what remains. They give equal weight to the spirits and history as built architecture.

Are you aware of similar comanagement agreements for parks or protected areas?
