I know of no place that currently issues residents 10 tags and Natives 50, but then I don't read all the regulations for every unit- only the ones I hunt in or have some other interest in.
When the NWACH took a nose dive in the 70's, residents were for a time then issued 5 permits (all one could get on a towed sleds at one time), and once those filled, if they needed more, got 5 more, etc. This was because of run and gun on snow machines, where the kill might be strung out for miles, and carcasses often not recovered. And people killing dozens, piling them up, and not recovering. A big cause of that decline was the chasing with snow machines, which IMO resulted in massive "spontaneous" abortion rate, affecting the decline even more than the wanton slaughter I personally witnessed.
Officially, it was a "mysterious" decline... They went back to no limits for residents once the herd recovered - and biologically, none are needed.
There was no resident limit on caribou take the two years in mid 90's that I spent in Barrow, nor the 8 years 2010-2018 we lived in Kotzebue. The last couple years in Kotz the Advisory Committee got ADF&G to rubber stamp the Native practice of not taking bulls from mid October to February- Rut and skinny...., tho edible shortly after rut.
I called this "the pregnant cows only season". Ostensibly to slow a decline in the caribou herd, but really just to integrate Native practice into regulation..
Yeah.....I know.....
To reinforce Art's description of Alaska's size is this:
If you pick your starting point and direction correctly (at least 2 ways it can be done), one can travel in a straight line for 1500 miles, and be halfway across the state....
I just returned from our remote cabin in north-central Interior Alaska, from our home on the Kenai Peninsula in South-Central. It's about 750 road miles from house to boat landing, and another 50 river miles to the cabin. And still south of the Yukon.
Alaska is fairly good sized, with multiple ecosystems and population centers, requiring a diverse regulation system, which is now far more complicated than when I first got here in 1968. At that time, the regulations ran to 10 pages or less for the entire state....
Ah, progress!
