There already is a lot of co-management going on in the Arctic. There are a lot of co-management boards already, where both indigenous people and people from the ministries have a co-management responsibility for harvestable species.
I think in particular about the Inuvialuit Joint Secretariat in the western Arctic. They have a co-management group there that sets the priorities for how harvesting occurs. They come to agreement on harvestable levels, and they have responsibility and co-management for it.
