Bag/possession limit is shared in aggregate across all 3 forest grouse species.Sparsely distributed; found in dense conifer forests generally from the Salmon and Payette river drainages north. Same Area 1 / Area 2 split and dates as ruffed/dusky grouse.
Forest grouse (spruce, ruffed, dusky) data comes from IDFG's post-season wing-barrel collection (juvenile:adult ratios), which is retrospective by design and feeds the following year's forecast narrative rather than standing alone as a pre-season 2026 report. That narrative sits inside the statewide/regional Upland Game Bird Forecast, which had not published as of 2026-08-19 (2025 edition published Sept 5, 2025); expected within the next 2-3 weeks.
