It is located on Lake Michigan at the Illinois state line and includes grassy wetlands, wooded areas, and the Kenosha Sand Dunes at its northern tip.

In 1947, a group of developers led by Joseph E. Shaffron bought most of the land to build homes for middle-class families.

[6] In the 1960s, a group of concerned citizens, led by Phil Sander and Al Krampert, organized to save the prairie by acquiring undeveloped tracts of land.

In 1993, WEC Energy Group donated 62 acres to the Nature Conservancy adding the Kenosha Sand Dunes to Chiwaukee Prairie.

In 2015, the entire Lake Plain from Chiwaukee Prairie south was designated a Ramsar wetland of International Significance.

Since 2014, the Nature Conservancy has acquired another 150 acres just east of Sheridan Road from 116th Street south towards the Illinois border.

And is there is a bewildering assortment of flowers including blazing stars, black-eyed susan, goldenrod, tickseed, milkweed, Queen Anne's-lace, lobelias, asters, thistles, and sunflowers.

[10] The prairie is home to more than 75 types of birds including gulls, ducks, vireos, swallows, wrens, finches, orioles, woodpeckers, turkey, hawks, kestrels, and bald eagle.

The prairie supports an abundance of insects, butterflies, amphibians, and reptiles, including the rare Blanding's turtle (a species of special concern).

The prairie is also home to many mammals such as woodchucks, minks, red foxes, coyotes, and the rare Franklin's ground squirrel.
