Bobalong, I think I am with you for the most part.

As of 2008, the number of Registered Indians was just over 100,000 in AB.

shows the majority of the population is skewed north of slave lake. Hunting pressure in AB by natives is seriously a drop in the bucket. Especially in the central and southern regions of the province, where it is land access, and not tag availability that limits the hunting pressure.
Besides a blind sense of injustice that another group of people is being treated differently, I don't think there is a logical conservation based argument to be made that native hunting is a problem.
As for Suffield specifically. Its basically a glorified game farm. Who cares who shoots the bulls? Once the numbers are down, I am sure whoever is in control can limit access to natives and non-natives alike.
