In Wisconsin, ruffed grouse is a stronghold. A stronghold. The northern and central forest is Zone A and holds the bird through a long season; the south-east is Zone B and thin. Wisconsin's huntable public estate is 4,969,547 acres across 507 units, not filtered by species because WDNR does not publish a per-parcel list. The best-supported of them is Chequamegon National Forest: 789,612 of its 863,436 acres lie in cells where the bird is recorded. Units here are ordered by how much of each one lies in subbasins where ruffed grouse is recorded at regular strength or better, not by how big the unit is. The list is also clipped to the ground WDNR opens a season on, which leaves 171 of the state's units eligible.

A stronghold. The northern and central forest is Zone A and holds the bird through a long season; the south-east is Zone B and thin.
Wisconsin's huntable public units. WDNR does not publish a per-parcel species list, so this is not filtered to ruffed grouse.
Ordered by recorded acres — how much of each unit lies inside subbasins where ruffed grouse is recorded at regular strength or better — rather than by how big the unit is. The biggest block in a state is often not in the half of it the bird is in. PAD-US splits a forest into many parcels, so acreage is summed over the unit's name, and the share is measured against the unit's drawn boundary rather than a centroid: a national forest can be two polygons across half a peninsula.

PAD-US says who manages a parcel, not where its boundary runs on the ground and not whether a unit carries a local closure. Context, not permission — check the unit with WDNR before you park.
The same ground read from where a reader starts rather than from the state line: the public units within forty miles of one town, ordered the same way. A town is on this list only where at least three units reach that far and hold ten thousand recorded acres between them.
