ATo identify and preserve a variety of natural and cultural landscapes through coordinated, publicly-based planning activities. The initiatives are to provide for resource preservation, public recreation, orderly development, public health and safety, and an enhanced quality of life for all citizens.@

HISTORICAL SUMMARY

 

The first known inhabitants of what is presently Douglas County were members of the early Amound builders@ culture. These were an advanced group of people that appeared on the shores of Lake Superior and throughout present day Wisconsin and Minnesota after the last glacier receded. These groups were followed by members of the Middle Woodland and Late Woodland cultures who inhabited much of present day Wisconsin until approximately 1200 A.D.

 

The next predominant indigenous group in the area was the Mascoutin (a branch of the Potawatomi nation) who subsisted on the region=s abundant game, wild rice and fish. They remained in the area until about 1400 when they were driven out by the Dakota (Sioux). The Dakota came to what is now Wisconsin from the east; being forced westward themselves by the Iroquois. From this time onward, there were successions of native tribes from the north and east of the United States and eastern Canada moving westward, invading and inhabiting the region. Around 1490, the Ojibwe (also known as the Chippewa) arrived in the area, coming around both the northern and southern shores of Lake Superior. The Ojibwe engaged in numerous bitter and bloody battles with the Dakota, eventually driving them westward into present day Minnesota and the Plains States.

 

Although historically undocumented, the first European reported to have visited the region was French explorer Etienne Brule. Brule, a voyageur for Samuel de Champlain is said to have circumnavigated Lake Superior between the years 1618 and 1623. By 1632, French maps of the area included ALac Superieur@ and the western end of the lake indicated as AFond du Lac@. Other French explorers and missionaries who traversed what is now Douglas County included Pierre-Esprit Radisson and Medard Chouart, Sieur de Grosseillers (1658-1661), Father Claude Allouez (1665), Daniel Greysolon, Sieur du Luht (1679-1680, namesake of the City of Duluth.), Nicolas Perrot (1671), Sieur Randin (1673) and Pierre Charles Le Seuer (1693).

 

The Brule-St. Croix waterway network that cuts diagonally across Douglas County was a vital link between Lake Superior and the Mississippi Basin. These two rivers were connected by the Brule-St. Croix Portage (today in the Town of Solon Springs) were used extensively by both indigenous peoples and Europeans.

 

The acceleration of the fur trade brought increased French presence to the area in the form of trade outposts, forts and Christian missions. A thread of the French legacy remains in Douglas County and across Wisconsin in a variety of French-influenced place names.

 

French rule came to an end in 1763 as New France fell to British control under the Treaty of Paris. The United States assumed control of the region in 1783 and perpetuated the fur trade begun by the French and British. Indigenous control of the area began to erode as increased white settlement took place throughout the upper Midwest. The Ojibwe title to the region was extinguished through a series of treaties in the 1840s that enabled settlers to move northward.

 

La Pointe County was created in 1845 in the northern portion Wisconsin Territory out of what encompassed all of present day Bayfield and Douglas counties and the northeastern counties of what was to become the State of Minnesota up to the modern Canadian border. Wisconsin achieved statehood on May 29, 1848 and government surveys were begun in the county in 1852 and completed by 1860. Douglas County itself was created from La Pointe County (renamed Bayfield County in 1866) on February 9, 1854. Douglas County originally extended as far south as the Namakagon River, but was adjusted first in 1856 and again to its present dimensions by 1864 with the creation of Burnett County.

 

The original name for Douglas County was to be St. Louis County, however, R.R. Nelson submitted an amendment to change the proposed name to Douglas County after his friend, Illinois Senator Stephen A. Douglas. Senator DouglasCfamous for his series of debates with Abraham LincolnChad financial interest in the new northern Wisconsin settlements. Superior was selected as the county seat, a Federal Land Office was opened there in 1855 and the city was formally incorporated in 1858.

 

The first Douglas County courthouse was built in 1871 and the present courthouse completed and occupied in March of 1920. It is an excellent example of the Beaux Arts style of architecture and is constructed of select Bedford blue cut stone and Pavanazza marble.

 

Railroads began to link the northern woods with the rest of the state in the 1870s. The first rail link into Superior and Douglas County was completed on December 17, 1881 as the Northern Pacific Rail line was completed. This marked the beginning of the emergence of Superior-Duluth as a global transshipment point for iron ore from Minnesota=s Mesabi and Vermillion Ranges, timber from the Northwoods and grain from the Plain States.

THE NATURAL ENVIRONMENT

INTRODUCTION

 

Land development policies, explicit or implicit, that are meant to accommodate growth plans and policies for land use location, roadways, sewer/water and extensions of municipal infrastructure. Land development must be based upon and be compatible with certain natural resource considerations that support or hinder land use activities. Natural resources are defined and identified as physiographic, geologic, vegetative, and hydrologic characteristics. Consideration of natural resource elements should shape, structure, and provide the pattern for land development and related activities.

 

The protection of certain natural resources is necessary for the welfare of both people and the environment. By allowing natural processes, such as the hydrologic cycle/system, to function without impediment, property, water supply, and environment are protected. The protection of natural resources also preserves important ecological communities. Certain natural resources have more than merely aesthetic and leisure-time activity values. They are essential to long-term human survival and the preservation of life, health, and general welfare. As such, the protection and/or management of these natural resources clearly are in the public interest. Thus, the analysis of those natural resources found within the study area is done for the purpose of directing development away from those areas not intrinsically suitable for a particular use and given the physical characteristics found within the study area, to at least guide development in a direction that is least disruptive. Many studies have been done to achieve this end, including the following reports that are hereby incorporated by reference.

Note: The Douglas County Land Use Plan is designated for the unincorporated areas (the towns) of Douglas County. The City of Superior, and the incorporated villages of Poplar, Lake Nebagamon, Solon Springs, Superior and Oliver are not included in this plan. These incorporated entities administer their own zoning, whereas zoning and land use controls in the unincorporated towns are administered by Douglas County. The incorporated units are responsible for creating and adopting their own land use plan, comprehensive plans or master plans as they see fit.

TOPOGRAPHY

 

Douglas County is located in the far northwestern corner of the State of Wisconsin and borders the southwestern shores of Lake Superior. Douglas County borders Bayfield, Washburn, and Burnett Counties in Wisconsin and Pine, Carlton, and St. Louis Counties in Minnesota. The county is 1,342 square miles in size. Figure 1 identifies the county=s internal political boundaries and roadway system.

 

Topographically, Douglas County varies from level, swampy lowlands to gently sloping and rolling uplands. The lowest point in the county is approximately 605 feet above sea level in the City of Superior on the Lake Superior lowland. From this low point, the land rises to nearly 1,200 feet above sea level at the top of the Superior escarpment towards the center of the county and then falls to approximately 1,063 feet in the southern portion of the county. Figure 2 illustrates the county=s topography.

 

Douglas County is divided between two of the five geographical provinces of Wisconsin. The Lake Superior Lowland Province covers the northern part of the county, that area formerly occupied by Lake Superior. The boundary closely coincides with the topographic boundary provided by the escarpments at the juncture of the Lake Superior sandstone with the older igneous rocks. In topography, it consists of a clay plain interrupted with moraine hills. The Northern Highland Province occupies that area south of the highest abandoned beach line of Lake Superior. About 70 percent of Douglas County falls within the Northern Highland Province, while the other 30 percent is part of the basin of the Lake Superior Lowland. Figure 3 illustrates the county in shaded relief with the hydrography, roadway networks and wetland areas.

 

The Continental Divide that separates the St. Lawrence (Lake Superior) and Mississippi River drainage systems passes through the middle of Douglas County. The major drainage streams, which lie north of the divide and empty into Lake Superior, are, from east to west, the Bois Brule, Poplar, Middle, Amnicon, Nemadji, and St. Louis Rivers. The St. Croix, Totagatic, and Upper Tamarack Rivers drain the southern part of the county. Streams and their 147 connecting lakes have a total direct drainage area of 1,010.37 square miles, 75.2 percent, of the county=s land surface area. Of this amount, 705.73 square miles drains directly into Lake Superior. The drainage areas of 284 landlocked lakes account for 84.7 square miles of surface drainage, 6.3 percent, while land areas that have no permanent surface waters account for 246.9 square miles, 18.4 percent, of the 1,342 square mile county area.

 

The landscape of Douglas County varies greatly from north to south. The Lake Superior Lowland which adjoins Lake Superior consists of a clay plain about 10 to 20 miles wide and slopes gently from the Superior escarpment to the lake. Short, swift streams flowing north into Lake Superior have cut deep V-shaped valleys below the plain. During the glacial period, the Lake Superior Lowland was submerged under glacial Lake Superior and red clay was deposited on the old lakebed.

 

The Superior escarpment, or Douglas Copper Range, is probably the most noticeable geologic feature in Douglas County. It extends east-west across the county from the Bayfield County line to Foxboro and, in some places, rises 350 to 400 feet above the lowlands. It is not a continuous bedrock range but is divided into three main ridges by the streams which cross it. These streams have cut deep gorges and have many rapids and falls where they drop from the hard rock of the escarpment to the soft clays and sandstones of the lowland. Pattison State Park, 11 miles south of Superior, includes two such falls. Big Manitou Falls on the Black River, the highest waterfall in Wisconsin with a 165-foot drop, is located on the cataract of the Superior escarpment. Little Manitou Falls, a second waterfall having a 30-foot vertical drop, is located about one mile upstream from Big Manitou Falls. Other waterfalls created by the Superior escarpment are located on Balsam, Miller, and Copper Creeks and the Amnicon River at Amnicon Falls State Park.

 

 

GEOLOGY AND SOILS

 

Ancient (Precambrian) sandstone and igneous bedrock underlie Douglas County. The northern part of the county is underlain with Superior red sandstone, over which is a thick mantle of clay and gravel, forming an artesian slope. Crystalline igneous rock underlies the southern two-thirds of the county, with gabbro and basalt outcroppings common along the Superior escarpment and Totagatic River of southeastern Douglas County. Figure 4 illustrates the county=s bedrock geology.

 

Glacial deposits, reaching 200 feet over bedrock in some places, cover most of the county. Those deposits covering the Lake Superior Lowland are generally shallow lake basin deposits; however, deposits in the old buried valley under the St. Louis River are known to have a thickness of nearly 600 feet. A large pitted outwash plain is located in the southeast part of the county. This plain is continuous from Bayfield County down through Douglas and into Washburn and Burnett Counties. The southwestern corner of the county is divided into elongated, narrow watersheds created by gravel eskers deposited during the Wisconsin period of glaciation. Most of these eskers lie in a northeast-southwest direction. Figure 5 illustrates the county=s soil types by their sub-order.

 

The soils of Douglas County, which greatly affect the chemical characteristics of surface waters, have been derived largely from the weathering of various glacial deposits. These deposits include lake deposits, glacial drift, and glacial stream deposits. Glacial lacustrine or red clay soils are found in the old lake plains adjoining Lake Superior. They were laid down under the waters of a larger glacial lake, which once occupied the Lake Superior basin. These calcareous red clay soils are finely textured, resulting in very poorly drained soils. These soils cover about one-fourth of the total county area and large quantities of groundwater. However, the overlying clay deposits effectively prevent this water from reaching the surface as springs and create artesian conditions. The small quantity of water that does reach the surface is usually of high quality and rich in carbonates and nutrients. The >Pine Barrens@ located in southeastern Douglas County, has light textured sandy outwash soils. These soils were formed from sands and gravel carried by water from the melting glacier; and because these deposits were water washed, there is a noted absence of large stones in the area. These acid soils are gray to brown in color and low in humus and nutrients.

FIGURE 1: DOUGLAS COUNTY

FIGURE 2: TOPOGRAPHY

FIGURE 3: SHADED RELIEF

FIGURE 4: BEDROCK GEOLOGY

FIGURE 5: SOIL ASSOCIATION BY SUBORDER

The groundwater in this area is extremely poor in carbonates and nutrients and reflects the low solubility of these overlying sandy soils. The topography is level to slightly rolling, and numerous lakes are located in the glacial sags and depressions of the area.

 

Glacial upland soils are found in the central and southwestern part of the county. These are the most extensive of all county soils and make up about one-half of the total county area. These soils consist of a heterogeneous mass of stones, silt loams, and red clays and belong to the same Wisconsin stage of glaciation. This glacial till varies from a few feet to several hundred feet in thickness and overlays a base of traprock. Lakes, swamps, and marshes are common in the depressions of this rough and hilly topography. In the extreme southeastern portion of the county, there are gray-brown loam soils, which are similar to the rolling, reddish-brown loams of the southwest part of the county.

 

Two other soils of Douglas County are the peat soils of the bogs, resulting from the accumulation of grass, sedge, leaves, and moss in poorly drained areas and the muck soils, resulting from the accumulation of organic and mineral matter in marshes and other wetlands. Exposed bedrock appears at the surface in only a few places.

 

Other geological characteristics that greatly affect water quality in landlocked lakes are the pitted nature of the underlying bedrock and the random, impervious clay pockets in the glacial till. The acidic nature of the soils, along with stabilized water levels, create ideal conditions for encroaching bogs which form in these depressions. The presence of 65 acid bog lakes with their characteristic types of vegetation is evidence of this condition.

 

 

CLIMATE

 

Douglas County has a humid, continental type of climate. This means that the county has long, cold winters with rather short, moderately warm summers. However, this climate is modified somewhat by the tempering influence of Lake Superior and by local variations in topography. Lake Superior acts as a large storage basin for heat (or cold) and thus tends to increase the number of frost-free days along the lake, but it also acts as a coolant during the summer. As a consequence, the extreme northern part of the county adjoining Lake Superior has longer growing seasons, cooler summers and slightly more precipitation than is found in the southern part of the county. The 140 to 160 days growing season along the lake is as long as the growing season in the extreme southern counties of Wisconsin.

 

Annual precipitation (32.1 inches) averages slightly more than the state average (31.0). Of the total annual average precipitation received, about 18.6 inches runs off into stream drainage systems. About 60 percent of the rainfall comes in spring and summer, with an average of 8 inches in March, April, and May and 11 inches in June, July, and August. June is the rainiest month and February is the driest. Mean snowfall in inches varies from 50 near Solon Springs to around 40 along the lake with snow blanketing the ground approximately 120 days in northern Wisconsin. The Duluth-Superior harbor is usually icebound from December until April; but Lake Superior itself normally does not completely freeze over.

 

Unlike most Wisconsin counties, there is some difference in temperature from north to south within the county. The lake modifies the narrow strip, which extends from Lake Superior southward to the Superior escarpment, so that summers are cooler and the winters milder than on the upland south of the escarpment. The waters of Lake Superior are much cooler than the land in summer and relatively warmer than the land in late fall and winter. Winds blowing over the water toward the land in summer keep the air cooler; whereas in fall and winter, winds from the lake tend to raise the air temperatures. However, the influence of the lake does not extend far inland, and southerly winds in summer bring warm days to southern Douglas County. The average annual temperature of Douglas County is 41 degrees Fahrenheit, with recorded extremes being 108 degrees Fahrenheit and B47 degrees Fahrenheit.

 

Douglas County is one of the largest counties in the state and also one of the most heavily forested. Over three quarters of the land area of Douglas County is forested. Large blocks of these forested areas are in a single ownership class, either county forest land or land controlled by paper companies. In addition, the soils of Douglas County in many parts of the county are very suitable for tree growth, more so than for agricultural crop production. This combination of factors results in a forest resource ideally suited for commercial wood and fiber production. A band of light sandy soils, approximately 10 to 12 miles wide, extending from south central Douglas County to east central Douglas County contains most of the pine acreage of the county. North of this band smaller areas of loamy soils and wetland or bog soils contain hardwoods and spruce-fir species, respectively. Aspen and birch predominate in the remainder of the county.

As mentioned previously, 79.8 percent of Douglas County is forested land. According to a Wisconsin Department of Natural Resources survey, of the 1,065 square miles of commercial forest in Douglas County, the present forest types are ranked as follows (square miles of each type):

Figures 6 and 7 illustrate the generalized land type association and habitat regions within the county. Three major land type associations are present; these include the Douglas Lake-Modified Till Plain occupying the northern third of the county, the Pattison and Dairyland Moraine region occupying the central and western areas of the county, and the Sand Barrens of the county=s southeast. Four broad habitat types persist including the Superior Clay Belt (generally corresponding to the Douglas Lake-Modified Till Plain area), Dry Mesic (generally corresponding to the Pattison-Dairyland Moraine region) Dry to Dry Mesic (corresponding to the glacial outwash lakes areas in the towns of Highland, Gordon and Wascott) and Dry to Very Dry (generally corresponding to the county=s sand barrens area). The following table lists the species which dominate each of these habitat regions.

COMMON PLANT COMMUNITIES

 

The forest vegetation of Douglas County is diverse and includes many of the upland and lowland forest plant communities found elsewhere across northern Wisconsin. These forest communities result from the soils, climate, disturbance, fire history, and other natural forces that occur here. Several forest plant communities are dominant here and account for a large portion of the forested landscape:

 

Boreal Forest:

The southern range of the true Boreal forest exists in the clay region of northern Douglas County. This community is commonly associated with shade-tolerant, long-lived species of spruce, fir, white cedar, tamarack, and white pine and associated hardwoods of white birch, aspen, and red maple. Here, past and present agricultural practices often exemplify successful stages whereby spruce, fir, and tag alder begin to invade abandoned farm fields.

FIGURE 6: LAND TYPE ASSOCIATIONS

FIGURE 7: HABITIAT TYPE BY LAND TYPE ASSOCIATIONS

Northern Forest:

Western and central Douglas County is predominated by this biological community. This community contains mixed deciduous and coniferous forests. This community is characterized as a climax habitat type, which is predominantly sugar maple. However, the drier conditions do not allow the sugar maple to develop to its full potential. Therefore, the more shade-intolerant species such as yellow birch, white ash, oak, and white pine will dominate the climax habitat type. Red oak and white pine show excellent growth if they occupy a dominant crown position.

 

Penokee Range:

This biological community is similar to the Northern Forest community. However, limited depth of soil and exposed rock outcroppings of the Penokee Range identify this community. This community lacks the well-drained soils of the Northern Forest community and supports those species more adapted to drier conditions. Habitat fertility enables a wide range of species to exist.

 

Pine Barrens:

This biological community is associated with jack pine, scrub oak, aspen, and red pine dominating glacial outwash sand plains. The climax forest will ultimately be red pine on the mesic sands; and scrub oak and jack pine will climax on the drier, nutrient-poor sands. Therefore, a climax forest would be a patchwork of trees, associated shrubs, and openings throughout.

 

Grassland:

The absence of trees and large shrubs and the dominance of small upland shrubs characterize the grassland community.

 

Wetlands and Bogs:

These communities are characterized by soils or substrate, which is periodically saturated or covered by water and further identified by vegetation types and water quality.

 

Aquatic Communities:

These communities include springs, ponds, lakes, streams, and rivers. These communities are also characterized by water quality.

FIGURE 8: GENERALIZED LAND COVER

WILDLIFE

 

The Douglas County Forest is habitat for a variety of species of bird, mammal, reptiles, amphibian, and insect life. Each species or group of associated species does best under different conditions related to the forest types and management within each biological community found on the county forest.

 

Many plant and insect species also occur on the forest; but unlike vertebrate wildlife species, no complete list is available as an inventory of insect species or native flora found on the forest. At this time, it is safe to comment that there are hundreds of individual species of insects as well as lichens, mosses, grasses, ferns, shrubs, and tree species that occur in the forest. Collectively these mammals, birds, reptiles, amphibians, insects, and plant species comprise the wildlife habitat of the forest.

 

Each type of plant community is important because of the habitat it provides to wildlife. Some types are more important to the wildlife resource because they are both abundant and use by many species such as jack pine, aspen, or northern pin oak. Types of lesser abundance such as white pine, northern red oak, upland brush, spruce-fir, swamp conifer, and grass openings are also important because they may provide the only breeding habitat available for some species or offer a critical habitat type that is needed seasonally.

 

 

ENDANGERED AND THREATENED SPECIES

 

A listing of endangered resources that are present on county-owned lands is available from the Wisconsin Natural Heritage Inventory (NHI). NHI is a database of rare, threatened, and endangered species and natural communities throughout Wisconsin. The following list is a summary of information regarding endangered land resources from NHI.

 

St. Croix Cedar Swamp:

A second growth white cedar and black ash swamp along the banks of the St. Croix River. Though young, the stand contains a diverse herbaceous layer including several orchid species. Last observed in 1994.

 

Mingan=s Moonwort:

This fern species of special concern is rare in its range from Labrador to Ontario south to Vermont and Wisconsin. It is found in a variety of habitats (meadows, riverbanks, sand dunes, and deep woods), and it is found in soils ranging from acid to circumneutral. One population was discovered in a maple-basswood forest in 1979.

 

Black Lake Bog:

This 2200-acre site is an exceptional resource. Identified natural communities are soft bog lake, northern wet forest, northern sedge meadow, open bog, and shrub-carr. Several species of concern are found at Black Lake Bog including LeConte's Sparrow, Northern Harrier, Timber Wolf, Lake Darner, and Green-striped Darner. Last inspection was in 1992.

 

Belden Swamp:

This huge wetland complex is an exceptional and unique resource in Douglas County. The large size and muskeg-like vegetation of this bog is not duplicated anywhere else in northwest Wisconsin. Portions are thinly vegetated with stunted black spruce and tamarack over ericaceous shrubs. Other parts are quite open with wire-leaved sedges and big birch dominating. Healthy populations of jutta arctic butterfly, LeConte's Sparrow, Yellow-bellied Flycatcher, and Northern Harrier have been identified on the bog. Last surveyed in 1989.

 

Moose Lake:

This lake is a small soft water bog lake that forms the headwaters of Moose River. The lake is fringed with alder and bog birch. Surrounding the fringe is a black spruce and tamarack bog. Last inspected in 1994.

 

Amnicon River Pines:

A small area of older red pines located north of the Amnicon River. Last inventoried in 1979.

 

Erickson Creek Forest and Wetlands:

This area is a diverse assemblage of different community types. The remoteness of the communities along with relative absence of recent disturbance elevates this area to a significant natural feature. The completeness of species assemblages in each community and their juxtaposition to each other makes this area unique in all of Wisconsin. Communities represented are open bog, northern wet forest, northern wet-mesic forest, northern hardwood swamp, northern sedge meadow, northern dry-mesic forest, boreal forest, and northern mesic forest. With an exceptional assemblage of natural communities within close proximity, diverse assemblages of species including rare species are possible. There are populations of several rare species found at this site. The bog and sedge meadow harbor populations of 15 special concern species: Three-toed Woodpecker, Great Gray Owl, Boreal Chickadee, Connecticut Warbler, LeConte's Sparrow, Bobolink, Northern Harrier, Sedge Wren, Dragon's Mouth Orchid, Freija Fritillary, Frigga Fritillary, Bog Fritillary, and the only location in Wisconsin for the Titania Fritillary. The denser conifers harbor Cape May Warbler and Swainson's Thrush. The mesic forest has two nesting pairs of the state-threatened Red-shouldered Hawk and the most westerly known population of Black-throated Blue Warbler. In the boreal forest an individual plant of the state-endangered Small Pyrola was discovered. Last inventoried in 1994.

 

Amnicon Boreal Fores:

A ten-acre stand of boreal forest with an overstory of red and white pine located north of the Amnicon River. Fire and past harvests were noted. Last inventories in 1982.

 

Erickson Creek Pine Forest:

Located south of the Amnicon River and west of Erickson Creek. Scattered islands of pine are present in the large open bog. Dominants are red and white pine with characteristic understory plants present. Last observed in 1980.

Ubreitzman Lake Bog:

This 13-acre, soft water bog lake is surrounded by 22 acres of spruce and tamarack forest. The shoreline is a floating bog mat. Boreal birds utilize the area for breeding. Last inventoried in 1994. Part of the area is in private ownership.

 

Lookout Tower Mound:

A series of rounded exposures of igneous rock. The north slope has a series of vertical cliffs that contain the state's largest population of fragrant fern, a species of special concern.

 

Nemadji River Floodplain Forest:

This floodplain forest along the banks of the Nemadji River contains a diverse flora including many canopy tree species. Large diameter silver maple, swamp white oak, basswood, white cedar, white spruce, and three species of ash are present. The spring flora is rich and mesic. Four state-threatened wood turtles were present in May. Last inventoried in 1994.

 

Buckley Creek and Barrens:

The creek is a slow, soft, cold water stream flowing from a spring pond, 4.5 miles to the St. Croix River. Most of the stream flows through swamp conifers composed of black spruce, tamarack, balsam fir, white cedar, and alder. The uplands to the east were burned in a forest fire in 1977. Pine barrens have reformed after the fire. Dominant trees are slow growing jack pine and Hill's oak. The barrens are nearly free of invasive exotic species. Plant and animal species composition indicate a diverse barrens community. Several new county records were found in the inventory. Barrens butterflies of special concern are dusted skipper, cobweb skipper, Henry's elfin, hoary elfin, coral hairstreak, striped hairstreak, and gorgone checkerspot. Last inventoried in 1994.

 

Flat Lake:

A shallow, soft water seepage lake with a fluctuating shoreline. The bottom is composed of muck and sand. Sedges and rushes dominate vegetation. Last inventoried in 1994.

 

Goose Lake:

A soft water seepage lake with a fluctuating shoreline. Sedge and rushes are the most common plants and 20 acres of sedge meadow adjoins the lake. Last inventoried in 1994.

 

St. Croix River:

The reach of the St. Croix a few miles up and down stream from the Highway T bridge has significant populations of rare species including the state-endangered pygmy snaketail dragonfly, the state-threatened gilt darter, and Blanding's turtle and special concern species, the rapids clubtail dragonfly.

 

Lappland Buttercup:

This boreal species was not known to occur in Wisconsin until 1994, when two populations were discovered. One is on DNR land along the Brule River. The other is on Douglas County land east of the St. Croix. Both locations are found in seeps in white cedar swamps. The species will definitely be considered a species of special concern and should be a candidate for endangered status. Further investigations need to be conducted to determine the extent of the populations and their habitat requirements. The Douglas County list of threatened and endangered species of plants animals and insects is listed in the following table.
