IDFG harvest by Game Management Unit, one row per unit per season per take method. Success rates and hunter days are published by IDFG and carried verbatim wherever a row comes straight from the department; nothing here is derived except where several hunts share one area, and there the rate is recomputed from the summed hunters and harvest because a per-hunt percentage does not survive being added up. Where a cell is blank IDFG suppressed a small sample, and it stays blank rather than being back-computed. Take method ("Any Weapon", "Archery", "Muzzleloader") is the variant for general seasons and the rows are NOT summable — each is its own season, not a component of a total. IDFG's own "All Weapons Combined" row is carried as the `all` variant, so the total is the department's arithmetic rather than ours. Idaho's draw-only animals have no general season at all. Moose, mountain goat and both bighorn herds appear under a `controlled` variant covering the limited-entry hunts, and the two sheep herds stay separate — a Rocky Mountain and a California bighorn are different animals in different mountains, with their own once-in-a-lifetime rules.
