Aurora Prairie


Surrounded by encroaching development, Aurora Prairie preserves and protects a rare piece of land for future generations — an original, intact prairie. From the Topeka Shiner a nearly-extinct minnow to one of the state’s rarest plants, the small white lady’s slipper, this preserve supports an abundance of plant and animal life.

Standing amid the wetlands flanking Medary Creek, one can begin to understand the diversity of life that once flourished here— from the beavers whose dam pools water in the dry summer months, to the snapping turtles that call it home and the waterfowl that fly overhead.

Many people don’t realize that America’s great prairies rivaled Africa’s Serengeti in its amazing diversity of wildlife and flora — from the herds of bison, elk and antelope to colonies of prairie dogs feasting on more than 250 species of plants – the American plains truly were breathtaking. However, of  the world’s many grasslands, America’s tallgrass prairie shows the greatest change, with only 1 percent of native prairie remaining.

Location
From Brookings Holiday Inn, travel 2.7 miles east on Highway 14. Turn right on the gravel road and travel south 3.5 miles. The preserve is on the east side of road and is marked by a large wood sign. Visitors may walk in from the gate located in the southwest corner of the preserve.

Plants
Each week, from March to October, at least a dozen different species of wildflowers bloom, each one taller than the last to stay eye-to-eye with the rising grasses. Aurora Prairie — with 120 species of plant life — offers an opportunity to see many of these wildflowers, including common lousewort, black-eyed Susan and Maximilian’s sunflower.

The majority of this preserve is dominated by tallgrass prairie plants with mesic prairie forbs. An area that drains into the nearby creek supports an abundance of grasses, rushes and sedges. Look for cattails and smartweed along the backwaters of the beaver dam.

Animals
Stately-looking great blue herons call this land home. They often arrive at dusk to dine on their favorite fish from Medary Creek. The rare webbed-toed Wilson's phalarope also can be found along this waterway. With its special toes, this bird spins on the water surface, creating tiny whirlpools that concentrate their aquatic prey for easy pickings.

Wood ducks and mallards frequent the waters of the beaver pond, and red-winged and yellow-headed blackbirds make their home in the nearby wetland vegetation. Bobolink, upland sandpiper, yellowthroat, grasshopper sparrow, savannah sparrow and the short-billed marsh wren also nest here.

Why the Conservancy Selected This Site
Native prairie is rare and precious in South Dakota.

In the 1970s, two conservation-minded citizens spent a year exploring South Dakota for these remaining ecological gems. They uncovered Aurora Prairie and launched a campaign to save it. The Nature Conservancy joined their mission of preserving and protecting this land for future generations.

The Conservancy has a long tradition of working collaboratively with partners — like these two men. By working together, more can be accomplished. Throughout South Dakota, the Conservancy enlists the help of communities, businesses, government agencies, multilateral institutions, individuals and other non-profit organizations.

What the Conservancy Has Done/Is Doing
Fire plays a natural role in prairies, clearing brush and encouraging the growth of native plants. Over time, plants on the prairie have evolved to thrive amid fire, which the Conservancy uses extensively as a management tool.

In the 1980s when scientists were just beginning to uncover the importance of restoring fire to ecosystems, Aurora Prairie was the site of a study that examined the importance of fire to control harmful, nonnative species.
