Cattle pasture some 40 acres immediately south of highway 72 and nec 
canopy or shrub layer is present. 
There are 28 man-made lakes and ponds covering 70 acres following 
the dashed line (Fig. 1). These lakes and ponds are largely steep-sided. 
and afford little emergent wetland or marsh vegetation. Bordering most of 
these water bodies is a narrow band of sedges, spikerush spp., cattail, and 
bullrush spp., but these plants are not extensive enough to attract many 
breeding aquatic or littoral zone birds. Most lakes and ponds are replete 
with such submergent or floating food-bearing plants as sago, curlyleaf. 
and leafy pondweed; lesser, and star duckweed, and broadleaf water milfoil 
Approximately 40 acres are planted to escape and nesting cover anc 
food plants for upland and song birds. These units have an equal acreage 
of grain food plants in a ratio of 3:1:1 as listed for the Fox River property 
Volunteer food plants growing within these strips are the same species 
as were recorded on the Fox River plantings. 
White pine, red pine, several crabapple spp., arrowwood virburnum. 
amur honeysuckle, tartarian honeysuckle, autumn olive, Russian olive, and 
silky dogwood have been planted for wildlife use. Herbaceous plants cul- 
tivated as nesting cover are wooly, sericea, and prostrate lespedeza; three 
varieties of switchgrass; creeping foxtail; reedcanary grass; crown vetch, 
and birdsfoot trefoil. 
The remaining 100 acres consist of the game farm, kennels, 13 miles 
cf interior roadways, parking lots, buildings and lawns. 
EASTERN FARMLAND UNIT—tThe eastern unit (Table 1) of 610 acres 
of farm land to the east of highway 25 (Fig. 1-C) is relatively flat with an 
elevation between 810 and 880 feet above mean sea level. 
Six soil types form the great majority of this unit, and three of the 
six types make up 70 percent or more. All six have definitely calcareous 
substrate. The three most prevalent types represent a deep, dark-colored 
surface soil formed on a region that was either timbered or a prairie in 
the past. They are well drained, with a high water supplying capacity, and 
are well suited for pasture, woods, agriculture, and wildlife. The other 
three soil types possess the same general characteristics, but they are 
less fertile. 
About 360 acres were planted to field corn in 1967. This corn is har- 
vested and only waste corn is taken by avian species as food. When mature, 
these cultivated plants form good escape cover. Alfalfa was planted on 120 
acres. This forms excellent escape cover when the plant is mature, and 
good nesting cover for late nesters. 
Fifty acres were planted to upland game-bird food strips systematically 
spread over the eastern unit, with the same species and ratio used here as 
on the Fox River and central unit plantings. Although primarily used for 
food, these plants provide useful escape cover. 
Two units of 15 acres each were planted, a number of years ago, as 
nurseries. Native and foreign species of coniferous and deciduous trees, 
as well as a wide variety of shrubs, were planted in dense rows. These 
nurseries have fallen into disuse as far as horticultural activities are con- 
cerned, but songbirds, some gamebirds, and small mammals use them 
extensively throughout the year as escape-nesting cover and food.
