Wisconsin State Natural Areas Program Seagull Bar (No. 37)

Overview

Location

Marinette County. T30N-R24E, Sections 9, 16. 43 acres.

Description

Description

Seagull Bar is a sand spit and marsh on the margin of Green Bay off the City of Marinette. It contains the only true dune complex along Green Bay and is an important migratory bird staging area. The sand spit shelters a lagoon and large area of shallow water with emergent vegetation. The eastern edge of the bar has a system of sand ridges and dunes that have resulted from wave action and sand deposition. The rich dune flora ranges from rush species in the wetter, sandy areas to marram grass, Canada rye, and beach pea on the dry dunes. The remainder of the area consists of mud flats and emergent aquatics. The acreage of exposed land is always changing due to the bay's fluctuating water level. The area is a noted bird migration stopping point on Green Bay. During some spring and fall migrations, shorebirds by the thousands congregate here. The lagoon in particular is attractive to waterfowl. Seagull Bar is owned by the DNR and was designated a State Natural Area in 1962.

Access

Driving directions

From the junction of Ogden Street and Leonard Street in the southeastern corner of the City of Marinette, follow Leonard Street east and south about 0.5 miles to Red Arrow Park along Lake Michigan. Walk southeast into the natural area.

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 reserve for Great Lakes beach and dune, as rare bird nesting habitat, as a significant geological site, and as an ecological reference area. Natural processes and beach enhancement will determine the structure of the natural communities of this site. Provide opportunities for research and education on one of the highest quality native Great Lakes dune and beach ecosystems.

Management approach

The native Great lakes beach and dunes are managed actively to reduce competition from woody and invasive species to enhance habitat for the federally-endangered Piping Plover. Other allowable activities across the entire site include control of invasive plants and animals, maintenance of existing facilities, and access to suppress wildfires.

Site-specific considerations

  • Predatory excluder devices are placed if Piping Plovers attempt nesting.
  • Access to the beach may be limited during the on nesting time for Piping Plover.
  • Other limits on access may be temporarily placed on the site when piping plovers are present.
  • Salvage of trees after a major wind event can occur if woody material affects trails and access, though 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.

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]
