The large regions take away the ability to change quota's (both up and down) in smaller geographic regions.
Again I'll use the proposed southern Region as an example. It covers an area from Laramie to the Utah/Idaho line and South of I-80.
Lets say the Snowy Range has a tough winter year, but elk are booming around Evanston, clear across the state.
The GF will be reluctant to cut the southern region total quota with elk doing very well in say the Sierra's and the general units near Evanston.
So, their only option would be to adjust season length in the Snowy Range to take pressure off a depressed elk herd. That would in turn, drive both Resident and Non Resident pressure to the Sierra's and the far Eastern units near Evanston.
What would that do? Likely create a crap experience due to hunter density, reduce total elk numbers, reduce bull to cow ratio's etc.
It would make way more sense if the Sierra's were a region, the Snowy Range was another Region, and the Evanston units were their own region. They could increase or decrease tags in a specific region, rather than just trying to shift shift pressure from one unit to another.
It wound also allow the Resident hunters that primarily hunt their specific region to work with the Department and regional wildlife managers to make sure NR tags and seasons were ensuring recreation management objectives. Tough to do that when your regions covers 1/4 of the state like the Southern Region would, or about 2/3 of the State in their Western region.
The Department had it wayyyyy more correct with the 13 regions, and then pivoted to 3 at the request of the outfitters, making the whole idea complete trash.
