Within the Northern Unit Kettle Moraine State Forest, Washington County. T12N-R19E, Section 15 W½NE¼. 42 acres.



Kewaskum Maple-Oak Woods consists of two parcels separated by old field and pine plantation that contain southern dry-mesic and mesic forest dominated by sugar maple, red oak, white ash, and basswood with some beech. Located just east of the Milwaukee River, the southern tract is hilly with southern, eastern, and western exposures and contains a very rich herb layer. Uncommon and interesting species include large-fruited snakeroot, dog violet, smooth bank cress, showy orchis, and putty root orchid. The northern tract is flatter and generally lower, containing very large red oak, white oak, sugar maple, and black cherry. Both parcels have kettle depressions that hold water seasonally. Common nesting birds include the black-billed cuckoo, great-crested flycatcher, eastern wood pewee, wood thrush, blue-gray gnatcatcher, and scarlet tanager. Kewaskum Maple-Oak Woods is owned by the DNR and was designated a State Natural Area in 1977.

  • WDNR


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.

Allowable activities

In general, the activities listed below are allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted under the "Access" tab above and posted with signs on site.

  • Hiking
  • Fishing
  • Cross country skiing
  • Hunting
  • Trapping

Prohibited activities

  • Camping and campfires
  • Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead. Collecting for scientific research requires a permit issued by the DNR
