Waupee Lake Swamp

County: Oconto

Forest: Nicolet

Ranger District: Lakewood-Laona

Established: 2015

Acres: 335

Description:The most important features of Waupee Lake Swamp RNA include a shallow seepage lake surrounded by swamp conifer forest plus thickets of alder and black ash.  The north and west edges of the lake are bordered by a muskeg-like forest of stunted tamarack and black spruce.  A diverse community of sedges, ericads, orchids, and insectivorous plants is also present, including three rare plants and six rare bird species. Plant communities include northern wet and wet-mesic forest, open bog, northern sedge meadow, and emergent aquatics.

Ecological Information

Physical and Climatic Conditions:

Nearest weather station, with distance and direction from RNA: Lakewood 3 NE (station no. 474523). The station is located about 15 mi (24 km) to the northwest of the RNA.

Annual precipitation (type, seasonal distribution): Annual precipitation averages 33 inches (84 cm), 65% of which falls between April and September. Average seasonal snowfall is 65 inches (164 cm).

Maximum and minimum temperatures: Daily summertime temperatures average 58° F; average daily maximum temperatures average 53° F. Average temperature in the winter is 25° F; average daily minimum temperatures average 30° F.

Elevation: Elevations range from 920 feet (280 m) to 950 feet (289 m) MSL.

Geology and Soils: The RNA is underlain by precambrian metamorphic rock.  Because  the area was glaciated during the Pleistocene, there are no surface exposures of this rock within the RNA.  The present surface material was deposited by the Green Bay lobe during the middle Woodfordian substage of the Wisconsin ice advance. Geomorphologic processes were glacial meltwater deposition.  Glacial sediment is less than 30 meters thick and landforms include ground moraine and outwash plains. 

Soils are loamy sand over sand.  Nutrient status is poor and moisture regime is dry to dry-mesic. Upland soils of the RNA are deep, moderately well-drained and formed in sandy loam aeolian material overlying loamy sand glacial till.  The area is covered by 0.5 meter or more of wind-blown sand. Wetland soils are organic, very poorly drained, slightly acid to neutral.

Aquatic Features:The 34-acre (14 ha) Waupee Lake is a hard-water seepage lake with a maximum depth of 2 feet (0.6 m).  The lake’s shoreline is 90 percent coniferous wetland and the entire littoral zone is silt.  Waterfowl make moderate use of the lake during migration. Emergent vegetation occupies sixty percent of the lake basin.  Waupee Lake has an intermittent outlet at the south end, which drains south through a large wetland area to Little Waupee Creek, a tributary of the North Branch Oconto River.

Common Fauna: Common mammals of the area include snowshoe hare (Lepus americanus), red squirrel (Tamiasciurus hudsonicus), white-tailed deer (Odocoileus virginiana), and black bear (Ursus americanus).  A variety of avian species have also been recorded by the Nicolet Breeding Bird Survey.  Waupee Lake is a shallow lake and does not support a significant fishery.

Common Tree Species: Most of the forested swamp surrounding Waupee Lake is dominated by northern white cedar (Thuja occidentalis).  Associated trees include tamarack (Larix laricina), black spruce (Picea mariana), balsam fir (Abies balsamea), black ash (Fraxinus nigra), red maple (Acer rubrum), paper birch (Betula papyrifera), yellow birch (Betula alleghaniensis), and eastern hemlock (Tsuga canadensis).  An open bog also supports a variety of bog dwarf-shrubland species.

Common Herbaceous Species: Characteristic ground flora includes bunchberry (Cornus canadensis), creeping snowberry (Gaultheria hispidula), three-leaved goldthread (Coptis trifolia), Labrador-tea (Ledum groenlandicum), and cinnamon fern (Osmunda cinnamomea).  Surrounding the lake are open wetlands dominated by sedges, bulrushes, bluejoint grass (Calamagrostis canadensis) and other grasses.  Associate species include eastern marsh fern (Thelypteris palustris), marsh cinquefoil (Potentilla palustris) , blueflag iris (Iris versicolor), and poison sumac (Toxicodendron vernix).  Emergent and floating-leaved vegetation include softstem bulrush (Schoenoplectus tabernaemontani), cattail (Typha latifolia), and American white waterlily (Nymphaea odorata).

Potential Research Topics: This would be a good area to study ecological aspects of the flora and fauna of this large contiguous complex of wetland communities.  Areas of focus include: amphibians, reptiles, birds, rare plants, regeneration of cedar and the natural dynamics of other wetland tree species complexes and wetland ecological adaptation to climate change.
