Wisconsin State Natural Areas Program Ekdall Wetlands (No. 150)


Overview

Location

Within Governor Knowles State Forest and the St. Croix National Scenic Riverway, Burnett County. T40N-R19W, Sections 25, 35, 36. 367 acres.

Description

Description

Ekdall Wetlands lies in a low terrace, 0.25 to 0.75 mile wide, where the St. Croix River has meandered away from the steep escarpment. The site contains northern wet forest and alder thicket plus a southern wet-mesic forest, here at its northern range limit in Wisconsin. Flat uplands above the escarpment are about 80 feet above the swamp and consist of barrens openings and dense stands of young oaks and jack pine. The escarpment slope also exhibits a continuum from xeric oaks at the summit to more mesic species midslope to swamp species at the wet base. Numerous seeps near the base contribute water to an open swamp of white cedar, tamarack, black spruce, black ash, and alder with scattered balsam fir and yellow birch. Typical understory species are sphagnum moss, Labrador-tea, pitcher plant, cat-tail, and sedges. Closer to the river are shrub-dominated thickets and small marshy pockets. The soils include wet alluvial land near the river, Cathro muck in the swamp, and sandy soils on the terrace escarpment. Deer use in the area is heavy. Other disturbance includes a ground fire that burned 75 percent of the understory in 1980 and some windthrow in 1977. Ekdall Wetlands is owned by the DNR and National Park Service. It was designated a State Natural Area in 1979 and later expanded to include the St. Croix River.

Access

Driving directions

From the junction of County Highways D and F in Grantsburg go north on County Hwy. F 6.9 miles, then north on Nelson Landing Road (when F turns east) 0.6 mile to a boat landing. Walk north along the river into the site.

Ownership

Ekdall Wetlands is owned by:

  • National Park Service
  • WDNR

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 floodplain forest reserve, an aquatic reserve and wetland protection site, and as an ecological reference area. Natural processes will determine the structure of the forest. Provide opportunities for research and education on the highest quality native floodplain forests.

Management approach

The native species are managed passively, which allows nature to determine the ecological characteristics of the site. Exceptions include control of invasive plants and animals, maintenance of existing facilities, and access to suppress fires. Salvage of trees after a major wind event is not considered compatible with management objectives.

Site-specific considerations

  • Although removal of hazardous trees from over and near trails is an allowed activity, manipulation/removal of vegetation and soil disturbance should be minimized to the extent possible.

Management

Management objectives and prescriptions

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.

Hunting and trapping

This SNA has multiple landowners: Opportunities for hunting and trapping depend on the land owner. In general, most DNR-owned land allows hunting and trapping. Partner-owned land may have other rules (for example, university-owned lands do not allow hunting or trapping). Please contact them directly to find out about their rules for hunting and trapping. You can find a link to other owner websites under the "Resource links" heading above. More details regarding allowable uses on the non-DNR land may be found under the "Access" tab above, if available.

Allowable activities: DNR-owned land

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: all 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]
