Overview

Location

Within Jefferson Marsh Wildlife Area, Jefferson County. T6N-R15E, Sections 5-9, 16, 17, 18. 1,633 acres.

Description

Description

Jefferson Tamarack Swamp harbors the largest forested wetland in Jefferson County and one of the most extensive in southeastern Wisconsin. The wetland is dominated by large stands of mature tamarack with extensive patches of sedge meadow, and thickets of willow and dogwood along the periphery. Associated with the tamarack are American elm, red maple, and black ash. A hummocky cover of sphagnum moss blankets the ground and poison sumac is abundant throughout the site. Other common shrubs include red osier dogwood, common winterberry, and willows. Bog birch is found in more open areas. Groundlayer species include cinnamon, royal, crested shield, sensitive, and spinulose wood ferns, skunk cabbage, and pitcher plant. Southern sedge meadow and emergent marsh of cat-tails and arrowhead border the tamaracks. The meadow is dominated by bluejoint grass, tussock sedge, lake sedge, spotted Joe-pye-weed, marsh fern, and marsh bellflower. The extensive acreage of the site makes it an important refuge for many bird and animal species. Located within the site is a 10-acre upland oak island containing one of the largest Native American mounds in Wisconsin. Jefferson Tamarack Swamp was originally purchased by Pheasants Forever and later transferred to the DNR in 2004. The site was designated a State Natural Area in 2003.

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.

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.

Entrance 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. For more information, see Wis. Admin. Code NR 45. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.

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

Although a handful of sites allow activities like primitive camping (e.g. Lower Chippewa River on sand bars) or horseback riding (e.g. S. Kettle Moraine), the activities listed below are generally prohibited on DNR-owned SNAs.

  • 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
  • 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]
