Overview

Location

Within Chequamegon-Nicolet National Forest, Taylor County. T32N-R1W, Section 1 S½SE¼. 38 acres.

Description

Description

Twin Lakes Bog features an undisturbed conifer swamp occupying a depression between two kettle lakes in an area of morainal topography. The swamp is dominated by tamarack with black spruce, red maple, and yellow birch. The understory has an open aspect with characteristic bog shrubs and herbs scattered on a mat of Sphagnum moss. Dominant shrubs are Labrador tea, bog laurel, and leather-leaf with mountain holly, and winterberry. The sphagnum mat contains several sedge species including two-seeded bog sedge and American woolly-fruit sedge with twinflower, cinnamon fern, bunchberry, and buckbean. Insectivorous plants are well represented with bladderwort, sundews, and pitcher plants. The understory is also notable for large number of moccasin flowers. Three small bog lakes, surrounded by quaking bogs, compliment the site. Also present is a small stand of second-growth northern hardwoods dominated by sugar maple and red oak, which surrounds the uplands to the west. Leopard and wood frogs are common. Birds include blue-headed vireo, hermit thrush, black-and-white warbler, and white-throated sparrow. Twin Lakes Bog is owned by the USDA Forest Service and was designated a State Natural Area in 1996.

Maps

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.

Recreation

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.

Non-DNR lands

Hunting and trapping

You can find a link to other owner websites under the "Resource links" heading above.
