CPW’s stratified-survey estimates for the whole herd unit (DAU) this GMU belongs to — published with the uncertainty the per-GMU tables can’t carry.

CPW estimates harvest, hunters, success and recreation days from its Big Game Harvest Survey. Unit tables run 2019-2024; the 2025 report switched to per-hunt-code tables without unit totals, so unit series end at 2024 and 2025 success rates appear on the draw-odds tables instead.

How these numbers are made

public_land_pct = public_area / unit_area
landlocked = public ∖ reachable(roads, corners)
remote = public ∖ buffer(roads, 1 mi)
