Some of the things that have been said are right on point. The North American waterfowl management plan is a great example we can learn from, in that it could be applied in areas like freshwater aquatic habitats.
I think there are some things specifically that government could do to help. One is long-term regional conservation planning. When I say regional, I mean vast areas, typically multi-province or certainly large watershed area planning that is typically beyond the scope of a private business or a conservation organization to take on.
Another would be improving incentives, such as a tax credit system that would apply to individuals and all people participating in conservation.
