Wisconsin State Natural Areas Program Shaky Lake (No. 180)

Shaky Lake, October 2000

Overview

Location

Outagamie County. T21N-R15E, Sections 7, 8. 221 acres.

Description

Description

Shaky Lake is a marl-bottomed bog lake surrounded by wire-leaved sedge meadow, tamarack swamp, and lacustrine forest. Grass-leaved pondweed, chara, and yellow pond-lily are the dominant submergents. Emergent aquatics include hard and soft-stem bulrushes and arrowhead with scattered clumps of cat-tail. A quaking sedge mat, containing wire-leaved sedges and many plant species characteristic of bog and fen communities, dominates most of the lake basin. A narrow zone of alders and willows form the transition from open mat to the surrounding forest of lacustrine hardwoods and tamarack. Summer resident wildlife includes green-backed heron, black duck, mallard, sharp-shinned hawk, broad-winged hawk, green frog, and bullfrog. The soils of the area are described as Granby, Shawano, and Emmet, all loamy sands and sandy loams, and shallow peat. Shaky Lake is owned by the DNR and was designated a State Natural Area in 1983.

Access

Driving directions

From the intersection of U.S. Highway 45 and County T, 1 mile northwest of Hortonville, go south on T 1 mile, then west on County TT 2 miles, then south on Ledge Hill Road 0.8 miles, just past a private driveway. Park and walk south 0.2 miles on a small volunteer footpath (a legal right-of-way) to the northeast corner of the SNA, which is marked with SNA boundary signs. The no trespassing signs refer to the lands east and west of the 66-foot wide right-of-way.

Ownership

Shaky Lake is owned by:

  • 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 reserve for northern wet forest, northern sedge meadow, and hard water bog lake, as an aquatic reserve and wetland protection site, and as an ecological reference area. Natural processes will determine the structure of the forest and wetlands. Provide opportunities for research and education on the highest quality native ecosystems.

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.

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]
