Manitowoc County. T18N-R22E, Section 32. 23 acres.



VanderBloemen Bog lies within the end moraine of the Valders stage of Wisconsin glaciation and contains an undisturbed open bog with successional patterns to hardwood swamp. The site features a quaking bog without open water. Typical bog species include pitcher plant, sundews, moccasin flower, and cranberries. Surrounding the open bog is a fringe of tamarack, black spruce, and white pine. The outer edge of the area is wooded with white birch, red maple, and black ash. Several small areas with different dominants give the site a heterogeneous aspect. Nesting birds include wood thrush, veery, crested flycatcher, ovenbird, northern oriole, and goldfinch. VanderBloemen Bog is owned by Silver Lake College and was designated a State Natural Area in 1966.

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.

The good majority of SNAs are isolated and have few or no facilities. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. Parking lots and lanes are not plowed during winter. Hiking trails may be nonexistent or consist of undeveloped footpaths. A GPS unit or compass and detailed topographic map are useful tools for exploring larger SNAs.
