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 Douglas Cfamous
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.

County in five categories including, urban/developed, forest, agricultural
open space, wetlands and open water. The following table describes the

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.
