Wisconsin State Natural Areas Program Owl Creek Fen Savanna (No. 521)



Within the Wood County Forest. T22N-R3E, Sections 12, 13, 14. T22N-R4E, Sections 7, 18. 814 acres.



Owl Creek Fen Savanna is a large peatland complex that supports a diversity of natural features including central poor fen, tamarack swamp, alder thicket, and upland islands of pine and oak. Of note are unique savanna-like stands of open-grown aspen situated in a wet meadow dominated by blue-joint grass. Central Poor Fens are acidic, low nutrient wetlands dominated by sedges including Carex oligosperma, C. lanuginosa, and C. utriculata. Found within the Central Sand Plains of Wisconsin, they often intergrade with Tamarack Swamp. Other characteristic species include three-way sedge, fowl manna grass, swamp-candles, cotton-grass, bog goldenrod, swamp milkweed, bulblet water hemlock, and blue-flag iris. Birds include sandhill crane, purple finch, black-and-white warbler, and golden-winged warbler. Owl Creek Fen Savanna is owned by Wood County and was designated a State Natural Area in 2006.

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.


Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.
