Dewey Marsh Wildlife Area


Overview

Location

Within Dewey Marsh Wildlife Area, Portage County. T25N-R8E, Sections 10, 11, 14, 15. 801 acres.

Description

Description

Dewey Marsh contains a large expanse of relatively undisturbed northern sedge meadow including smaller islands of tamarack and black spruce swamp, paper birch and white pine woods, and ericaceous bog. The marsh is dominated by blue-joint grass, steeple bush and wire-leaved sedges, with cat-tails and bur-reed. It forms the headwaters of Hay Meadow Creek. Scattered throughout the area are islands of aspen, birch, and white pine. Tamarack and black spruce swamps are also present. The eastern arm of the marsh is relatively cold and acidic containing an ericaceous bog while the western and southern portions are more alkaline. Rocks are exposed in many areas and there is little peat formation under the sedge mat. Large areas of peat and several acres of tamarack-spruce swamp, shrub carr, and red oak-white pine forest were destroyed in a large fire in 1976. Wildlife use is extensive with a diversity of rare species. Dewey Marsh is owned by the DNR and was designated a State Natural Area in 1976.

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.

Objectives

Site objectives

Manage the site as a northern sedge meadow reserve, as a wetland protection area, and as an ecological reference area. Natural processes and prescribed vegetation manipulation will determine the structure of the natural communities. Provide opportunities for research and education on the highest quality sedge meadows.

Management approach

The sedge meadow species are managed actively through tree/shrub control using tree harvest, brushing and fire to mimic natural disturbance patterns. Other allowable activities include control of invasive plants and animals, and access to suppress wildfires.

Site-specific considerations

  • Roadside easement area may be managed sporadically by township.

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.

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
  • Collecting of plants including seeds, roots or other non-edible parts of herbaceous plants such as wildflowers or grasses
  • Drone use, unless authorized by a SNA research permit
  • Geocaching
  • Horseback riding
  • Rock climbing
  • Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use

For rules governing state-owned SNAs and other state lands, please consult Chapter NR 45 Wis. Admin. Code [exit DNR]
