Overview

Location

Within Big Eau Pleine County Park, Marathon County. T26N-R5E, Section 13. T26N-R6E, Section 18. 87 acres.

Description

Description

Big Eau Pleine Woods is an old-growth northern mesic forest located on a sloping peninsula that projects south into the Big Eau Pleine Reservoir, an impoundment of the Big Eau Pleine River. Sugar maple dominates the old growth forest with basswood, yellow birch, hemlock, and red oak. The largest trees occur on a small hilltop with a younger mixed-species forest occurring on the slopes. The gently rolling moraine contains numerous tip-up mounds and fallen, decaying trees afford a variety of microhabitats for plants and animals. The understory is rich with a diversity of spring ephemerals such as trillium, violets, hepatica, and bloodroot. Rare and uncommon nesting birds include cerulean warbler (Dendroica cerulea), Acadian flycatcher (Empidonax virescens), olive-sided flycatcher, and yellow-throated vireo. Big Eau Pleine Woods is owned by the Marathon County and was designated a State Natural Area in 1990.

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
