Lower Chippewa River on sand bars) or horseback riding (e.g. 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.Īlthough a handful of sites allow activities like primitive camping (e.g. In general, the activities listed below are allowed on all DNR-owned SNA lands. However, please contact the landowner for more information. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. A GPS unit or compass and detailed topographic map are useful tools for exploring larger SNAs.Įntrance fees: Excepting Parfrey's Glen, the Cambrian Outlook in the Dells of the Wisconsin River, SNAs within State Parks and some within State Forests, all other DNR-owned SNAs do not have any admission fee. Hiking trails may be nonexistent or consist of undeveloped footpaths. Parking lots and lanes are not plowed during winter. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. The good majority of SNAs are isolated and have few or no facilities. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. Trails, if present, are typically undesignated footpaths. Parking lots or designated parking areas are noted on individual SNA pages and maps. Generally, there are no picnic areas, restrooms, or other developments. Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Bibon Swamp is owned by the DNR and was designated a State Natural Area in 1992. Other communities of lesser areal extent include northern sedge meadow composed of Carex species and blue-joint grass, and patches of riparian woodlands, dominated by American elm, green ash, and red maple, along the White River. Vast shrub swamps composed of slender willow, red-osier dogwood, and speckled alder, blanket portions of the wetland. Birds found in these coniferous peatlands include palm warbler, yellow-bellied flycatcher, boreal chickadee, and sharp-shinned hawk. Deep sphagnum hummocks form a continuous ground cover upon which ericaceous shrubs grow including leather-leaf, bog laurel, and Labrador-tea. North of the river conditions are very different, with a large complex of peatland communities including open bog, spruce-tamarack muskeg, and black spruce swamp. Black and white warbler, veery, and red-eyed vireo are common nesting birds. Bordering the cedar swamp is wet forest dominated by black ash, with a groundlayer of speckled alder, sensitive fern, wood nettle and poison ivy. Resident birds include Nashville, parula, and Canada warblers, and winter wren. Bunchberry, twinflower, small bishop's-cap and a number of orchid species are representative of the groundlayer here. Portions are forested with a rich wet-mesic conifer swamp of medium-sized white cedar, although trunk coring revealed that at least parts of the stand are in excess of 150 years old. The community types of this 15-square mile lowland are unusually varied for such a topographically uniform basin. Description Descriptionīibon Swamp, the largest wetland in Bayfield County, occupies the basin of an extinct glacial lake drained by the White River, a hard, cold water trout stream.
