Bag/possession limit is shared in aggregate across all 3 forest grouse species (dusky, ruffed, spruce) - not a separate per-species limit. Most common forest grouse in northern Idaho, found in riparian/moist mountain brush habitat. Area 1 = Panhandle/north-central counties (Benewah, Bonner, Boundary, Clearwater, Kootenai, Latah, Lewis, Nez Perce, Shoshone, plus parts of Adams and Idaho counties); Area 2 = remainder of state.
Ruffed grouse reaches its highest Idaho densities in the northern part of the state, though independent hunting-press sourcing confirms real, lower-density populations extend into the mountains of central, eastern, and southeastern Idaho as well — distinguishing it from spruce grouse, whose Idaho range is far more restricted. IDFG's own forest-grouse habitat reporting describes the species' preferred habitat as riparian areas and other moist mountain-shrub habitat, mid-elevation creek bottoms, and north-facing slopes and draws — moister, brushier ground than dusky grouse's more open, higher-elevation habitat. This north-concentrated pattern is also reflected in IDFG's own regulatory structure: forest-grouse Area 1 (the Panhandle counties plus northern Clearwater-region portions of Adams and Idaho counties) gets a five-month season (Aug 30-Jan 31), while Area 2 (the rest of the state) gets a four-month season (Aug 30-Dec 31) — a real, if indirect, agency-drawn signal that the species' core population sits inside Area 1.
Preliminary: Idaho's statewide forest-grouse forecast hasn't published as of August 29 (last year's edition came out September 5), so there's no real ruffed grouse count or survey to rate against yet. What we do know: statewide temperature and precipitation were close to normal this year, precipitation even slightly above normal since January, and winter 2025-26 was mild with very little snow, unremarkable conditions, not a red flag. Idaho is also dealing with a confirmed drought this year, but it's specific to the sagebrush country in the south that sage grouse and sharp-tailed grouse use, not the riparian and mountain-brush cover ruffed grouse favor in the north, so that concern doesn't carry over here. Treat this rating as a placeholder rather than a real read on the season; check back once the statewide forecast publishes, expected in early September.
No forest-grouse survey has published yet for Idaho; rated flat in the absence of any confirmed good or bad news, not from an actual count.
