Sand Prairie
Characteristics
The different prairie types in Illinois were the result of variations in soil moisture, soil composition, geological substrate, glacial history and topography. Sand prairies developed on the extensive sand deposits that were left when the glaciers melted. They also formed on sand dunes that were blown up by the wind, such as along Lake Michigan. Well‐drained, sandy soils are characteristic of sand prairies.
What Lives Here?
Because the prairie ecosystem is recently evolved, few prairie species are restricted to the prairie habitat and may be found in other habitats as well. Plants tend to be more characteristic of specific prairie habitats than animals. Plants that grow in the sand prairie are adapted to grow in well‐drained soil. These plants are typically shorter than those in black soil prairies. Little bluestem, leadplant, green milkweed, butterfly-weed, purple coneflower, prickly pear cacti, colic root, grass pink orchid, silvery bladderpod, blackjack oak, bearberry and winged sumac are all plants of Illinois sand prairies. The American badger, Strecker's chorus frog, common tern, western meadowlark, yellow mud turtle, gopher snake and plains hog‐nosed snake are animals typically found in this prairie type.
