Wisconsin State Natural Areas in numbers

Natural areas are small on average, so the region spread matters more than acreage.

Bibon Swamp State Natural AreaLargest

The program counts 669 natural areas; 441 hold DNR-owned parcels and are listed here (one page per SNA number, plus 12 natural-area properties without a number). The other 228 belong to the Forest Service, the Park Service, counties, the university or conservation groups and follow those owners' rules.

292 of these SNAs sit mostly inside a larger DNR property (a wildlife area, state forest or riverway) and link to it; 31 include parcels owned by someone other than the DNR. NR 45 bans camping, vehicles, drones and collecting plants on SNA land, so plan to walk in and carry everything out. Most have no species list, so every open season applies there within those rules.

Counted by DNR region, the natural areas split Northern 136, West Central 105, South Central 89, Northeast 87 and Southeast 33. Biggest natural areas by acreage: Bibon Swamp State Natural Area (9,613 acres), Spread Eagle Barrens State Natural Area (6,619 acres), Quincy Bluff and Wetlands State Natural Area (6,607 acres), Namekagon Barrens State Natural Area (6,433 acres) and Turtle-Flambeau Patterned Bog State Natural Area (5,461 acres). 4 natural areas carry posted refuges or restricted zones.

The Northwoods (Northern): 136 natural areas, the largest Bibon Swamp State Natural Area at 9,613 acres, most of them in Vilas County. Northeast Wisconsin (Northeast): 87 natural areas, the largest White River Sedge Meadow State Natural Area at 3,103 acres, most of them in Door County. West-central Wisconsin (West Central): 105 natural areas, the largest Quincy Bluff and Wetlands State Natural Area at 6,607 acres, most of them in Jackson County. South-central Wisconsin (South Central): 89 natural areas, the largest South Bluff/Devil's Nose State Natural Area at 3,492 acres, most of them in Sauk County. Southeast Wisconsin (Southeast): 33 natural areas, the largest Cedarburg Bog State Natural Area at 1,757 acres, most of them in Sheboygan County.

Wisconsin State Natural Areas: questions

Can I hunt in Wisconsin State Natural Areas?

Yes on DNR-owned land unless a site is posted closed. Three SNAs (Cedar Grove Hawk Research Station, La Crosse River Trail Prairies, Little Bear Hemlocks) are closed by deed restriction.

Can I drive or camp on an SNA?

No. Vehicles, camping, drones and plant collecting are prohibited under NR 45.

Why is an SNA missing from this list?

Only SNAs with DNR-owned land are listed. 228 natural areas have no DNR parcels; hunting there depends on the owner.

Which game can I hunt on an SNA?

Most SNA pages name no species, so every open season applies on the DNR-owned acres, within the property rules.

How big are the natural areas?

They range from a few acres to 9,613 acres of DNR-owned land.

Pick a property from the state natural areas list

Each natural area page links its DNR property map; use it to tell DNR-owned parcels from land held by others before you walk in.
