As publishedZone A: Sept. 12, 2026 – Jan. 3, 2027; Zone B: Oct. 17 – Dec. 8, 2026
Zone A and Zone B have different season lengths.HIP certification is required only if mixed-bag hunting with a migratory species (e.g., woodcock); not required for grouse alone (confirmed by WI DNR ruffed grouse page). Bag limit confirmed verbatim from WI DNR's live regulations tool (Fall 2026-Spring 2027 edition).
Wisconsin regulates ruffed grouse through two hunting zones (Zone A: northern and western Wisconsin, west of US Highway 151, longer season and 5-bird daily bag; Zone B: southeastern Wisconsin, shorter season and 2-bird bag), a season-timing/pressure split that loosely tracks, but is not identical to, the state's own biological monitoring geography. Since 2021, DNR has organized its spring drumming-count survey data by three named Ruffed Grouse Priority Areas defined in the Wisconsin Ruffed Grouse Management Plan 2020-2030: Northern, Central, and Driftless. DNR's own drumming-count monitoring consistently finds Northern Wisconsin the clear density leader among the three, with the Driftless priority area (the unglaciated southwest, including Buffalo, Crawford and Vernon counties) the lowest and most volatile. The Driftless area sits geographically within Zone A's boundary despite being the state's lowest-density priority area.
Wisconsin's 2026 Ruffed Grouse and Pheasant Survey showed an 11% statewide decline in drumming activity, with the largest drops in the Driftless and Central priority areas. The state's own wildlife biologists frame this as an expected turn in the species' roughly 10-year population cycle: low points tend to land in years ending in 4, 5, or 6, and 2026 fits that pattern. The strong 2024-25 numbers were themselves a product of unusually good nesting weather in those years, not a new normal this year fell away from. An expected cyclical dip, not a red flag.
The species' roughly 10-year population cycle entering its expected low phase, per Wisconsin DNR — not a named weather event this year.
