Echo Lake

County: Forest and Vilas

Forest: Nicolet

Ranger District: Eagle River-Florence

Established: 2014

Acres: 478

Description: Echo Lake RNA protects several eastern hemlock (Tsuga canadensis) and hardwood stands (yellow birch (Betula alleghaniensis) and sugar maple (Acer saccharum)) that are among the oldest, least disturbed, structurally and compositionally intact communities on the Chequamegon-Nicolet National Forest. The principal features of Echo Lake RNA are a soft-water seepage lake with a surrounding bog mat, and several stands of mature hemlock/hardwood forest situated on rolling moraine. The RNA also contains a mosaic of wetland types that includes northern wet forests dominated by black spruce (Picea mariana) and tamarack (Larix laricina), white cedar swamp, alder thicket, and open bog.  The mix of community types in this RNA supports several rare species including the gray jay (Perisoreus canadensis) and American ginseng (Panax quinquefolius).

Ecological Information

Physical and Climatic Conditions:

Nearest weather station, with distance and direction from RNA: Eagle River (station no. 472314) located about 13 mi (21 km) to the west of the RNA.

Annual precipitation (type, seasonal distribution): Annual precipitation averages 30 inches (76 cm), 69% of which falls between April and September. Average seasonal snowfall is 53 inches (134 cm).

Maximum and minimum temperatures: Daily summertime temperatures average 57° F; average daily maximum temperatures average 51° F. Average temperature in the winter is 23° F; average daily minimum temperatures average 30° F.

Elevation: Elevations range from 1,680 feet (512 m) to 1,750 feet (533 m) MSL.

Geology and Soils: Bedrock of the area includes igneous, metamorphic, and volcanic rock. Bedrock is greater than 100 feet from the land surface. Geomorphologic processes were glacial meltwater deposition with a surface of collapsed outwash plain.

A large area of the central and southern portion of Echo Lake RNA includes the Stambaugh soil series. Other soils include Carbondale, Greenwood, Pence, and Padus series.

Aquatic Features: Aquatic features include Echo Lake, a 13-acre (5 ha) slightly acidic, very clear, soft-water seepage lake with a maximum depth of 12 feet (3 m). There is no development along the 0.57 mile (0.9 km) lakeshore but there is an unimproved carry-in boat access.  A small tributary of Ninemile Creek flows from a conifer swamp through the northern part of the RNA into Upper Ninemile Lake impoundment.  It is a soft-water stream with slightly alkaline, light brown-stained water and is likely inhabited by brook trout (Salvelinus fontinalis). The stream bank is predominantly sedge mat or alder but a portion is shaded by boreal-like forest.

Common Fauna: Echo Lake RNA has not had a detailed faunal inventory, however two Nicolet Breeding Bird Survey points are located within the RNA.  The RNA provides nesting habitat for numerous neotropical migrant birds, habitat to rare birds such as the yellow-bellied flycatcher (Empidonax flaviventris) and several protected bat species. This site is embedded within an area recognized by the Wisconsin Bird Conservation Initiative as an Important Bird Area, which by definition provides essential habitat to one or more species of breeding or non-breeding birds.

Common Shrub Species: The understory is open with few shrubs and contains small canopy gaps filled with sugar maple saplings. Shrubs present include beaked hazelnut (Corylus cornuta), leatherwood (Dirca palustris), American fly-honeysuckle (Lonicera canadensis), and velvet-leaf blueberry (Lonicera canadensis).

Common Herbaceous Species: The groundlayer is dense in some areas and supports American ginseng (Panax quinquefolius) which is a species of viability concern on the CNNF. Characteristic species include jack-in-the-pulpit (Arisaema triphyllum), shining club-moss (Huperzia lucidulum), intermediate wood fern (Dryopteris intermedia), three-leaved goldthread (Coptis trifolia), and blue cohosh (Caulophyllum thalictroides).

Potential Research Topics: Echo Lake RNA contains two long-term monitoring plots in the Nicolet Breeding Bird Survey, providing a useful baseline for studies of bird population dynamics.  It also provides opportunity for studies of old growth northern mesic forests, wet mesic forests, acid bog lake systems, and rare plants including the economically important ginseng.
