Prairie Restoration Ignites Wisconsin’s ‘Sea of Grass’ with Biodiversity
Madison, WI – August 16, 2025 – Once a vast expanse described as a boundless “sea of grass,” teh American prairie is experiencing a renaissance. Restoration efforts in Wisconsin, exemplified by the Schurch-Thomson Prairie, are meticulously re-cultivating these vital ecosystems, bringing back a vibrant tapestry of life that rivals a bustling festival crowd. Experts and volunteers are working tirelessly to revive these landscapes, which have faced meaningful decline due to agricultural development and habitat loss.
A Living Canvas of Color and Scent
Early August at Wisconsin’s Schurch-Thomson Prairie transforms the landscape into a pointillist masterpiece. golden black-eyed Susans, the distinctive spires of blazing star, and vibrant purple coneflowers create a dynamic palette that shifts from April through October. Britta Petersen of Pheasants Forever highlights the constant evolution of the ecosystem, stating, “Its always different, it’s always exciting. You don’t know how diverse it is until you get in there.”
The olfactory experience of the prairie is equally captivating. Visitors can inhale the minty notes of Bee Balm, the citrusy aroma of purple prairie clover, and the earthy scent of Prairie dropseed. Rich Henderson, site steward for The Prairie Enthusiasts, notes that Prairie dropseed’s fragrance can be reminiscent of buttered popcorn as its seeds ripen. Ann Calhoun of The Nature Conservancy humorously counters that it can also smell like “dirty socks.”
The crucial Role of Prairie ecosystems
historically, prairie ecosystems stretched from the Rocky Mountains to east of the Mississippi River. Today, onyl a fraction of this natural heritage remains, with much of Wisconsin’s prairie and oak savanna transformed by agriculture and urban development.This conversion has led to diminished pollinator populations, a significant loss of ground-nesting birds, and increased issues with soil erosion and water runoff.
Restoration projects, such as those at Schurch-Thomson Prairie, are actively working to reverse this environmental damage. This 193-acre site, part of the 95,000-acre Military Ridge Prairie Heritage Area, was used for crops until the mid-1980s. Years of sod redevelopment have helped rebuild the soil, now paving the way for the reintroduction of native prairie plants. Henderson estimates that it could take two centuries for these restored areas to fully resemble the original prairie.
The prairie is a complex ecosystem with profound environmental benefits that are often overlooked.
Collaboration: A Team Sport for Grasslands
Grassland conservation is a collaborative effort, as emphasized by Andy Bingle, Coordinator for the Southern Driftless Grasslands Partnership. In areas like southwest Wisconsin, where 95% of the land is privately owned in small parcels, engaging thousands of landowners is essential. The partnership, which includes organizations like The Nature Conservancy and Pheasants Forever, works to restore grasslands across the upper Midwest.
Volunteers play a critical role, planting native seeds and removing invasive weeds to allow native grasses to re-establish. “Some species move easily, the wind carries them, and others don’t,” Henderson explains. “It’s going to take a long time, so we’re accelerating the recovery process.”

reviving Bird populations and Soil Health
The restoration of grasslands is crucial for the recovery of rare grassland birds, whose populations have seen a significant decline. Since the 1970s, these bird groups have experienced a 43% decrease, more then any other avian group. Fortunately, even non-pristine grasslands can support many bird species, and many are already returning to restored habitats.
The rich biodiversity extends beyond birds, encompassing a dense community of insects. Monarch butterflies, as a notable example, rely on milkweed for their caterpillars. Beneath the surface, prairie grasses boast root systems that can extend two to four times deeper than their above-ground growth. this makes well-managed grasslands significant carbon reserves, contributing to climate change mitigation.
Did You Know? The extensive root systems of native prairie grasses can extend several feet into the soil, aiding in carbon sequestration and soil stabilization.
Fire: An Ancient Tool for Prairie Rebirth
For millennia, Indigenous peoples understood the vital role of fire in prairie ecosystems. Prescribed burns stimulate seed production,encourage deeper root growth,and prevent woody encroachment-a major threat to grasslands worldwide. Following a 20th-century suppression of natural fire cycles, conservationists are reintroducing controlled burns to foster this natural regeneration process.
“It stimulates the native plants that are used to the fire and gives them a competitive edge,” Henderson explains. Volunteers are also actively involved in seed collection and processing. Using methods ranging from simple sieves to hammer mills,they prepare seeds for planting,ensuring the propagation of native species. This hands-on approach is crucial for accelerating the ecological recovery.
Evergreen Insights: the Enduring Value of Prairies
The prairie ecosystem, often perceived as a simple grassland, is in reality an incredibly diverse and dynamic environment. Its restoration offers profound ecological benefits, including enhanced biodiversity, improved soil health, and significant carbon sequestration potential. Understanding the historical role of natural processes like fire and the collaborative efforts required for conservation provides valuable lessons for ecological management globally. As seasons change, so does the prairie’s appearance and the chorus of its inhabitants, reminding us of nature’s continuous cycle of renewal.
Pro Tip: Supporting local conservation organizations through volunteering or donations is a direct way to contribute to the preservation and restoration of these vital natural landscapes.
Frequently Asked Questions About Prairie Restoration
- What is the primary goal of prairie restoration efforts?
- The primary goal of prairie restoration is to revive biodiversity, improve soil health, and re-establish the ecosystem’s natural functions, including water filtration and carbon sequestration.
- How long does it take for a restored prairie to resemble an original prairie ecosystem?
- Estimates suggest it can take up to 200 years for a restored prairie to fully replicate the complexity and appearance of an original prairie ecosystem, though significant ecological benefits can be observed much sooner.
- What role does fire play in prairie ecosystems?
- Fire is a natural agent of rebirth in prairies, stimulating native plant growth, enhancing seed production, encouraging deeper root development, and preventing the encroachment of woody vegetation.
- Why is grassland conservation considered a “team sport”?
- Grassland conservation is a team effort because much of the land is privately owned, requiring extensive collaboration with numerous landowners, conservation groups, and government agencies to achieve restoration goals.
- How do prairie root systems contribute to environmental health?
- Prairie grasses have extensive root systems that can be several times deeper than their above-ground growth, which is crucial for stabilizing soil, preventing erosion, and sequestering significant amounts of carbon underground.
