Overview

Location

Bayfield County. T50N-R7W, Sections 1, 2. T51N-R7W, Sections 35, 36. 646 acres.

Description

Description

Bark Bay Slough consists of a coastal barrier spit, lagoon, springs, and wetlands occuping an embayment between two rocky headlands along Lake Superior. The wetlands are extensive and include two major types: coastal fen and coastal bog. The fen dominants are woolly sedge, twig rush, sweet gale, water horsetail and buckbean . The coastal bog is composed of a mat of Sphagnum mosses, ericaceous shrubs, sedges, carnivorous plants and scattered small tamarack. Both communities are floristically diverse, in excellent condition, and support many rare species. A forested interior sand spit parallel to the coastal barrier spit (or 'bay-mouth bar') breaks the wetlands into two major sections. The sandy, 2-mile long barrier spit contains red pine and white pine with an understory of blueberry, bearberry, alder, sweet gale, and beach grasses. A large lagoon occupies the center of the site and supports submergent and floating-leaved aquatic plants. Together, the wetlands and 28-acre lagoon form a bay-mouth bar lake. The shallow (8 foot maximum depth), hardwater lake supports mostly panfish and northern pike. The Bark River, and a spring complex on the eastern end of the natural area supply water to the lake and wetlands. Birds present during the breeding season include bald eagle, sandhill crane, Brewer's blackbird, and American bittern. Substantial numbers of migrating shorebirds make use of the property. Bark Bay Slough is owned by the DNR and was designated a State Natural Area in 1977.

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.

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
  • Geocaching
  • Horseback riding
  • Rock climbing
  • Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use
