When most people picture the Midwest before settlement, they imagine endless fields of corn and soybeans. In reality, much of Illinois, Iowa, Wisconsin, and the surrounding states were once covered by vast expanses of native tallgrass prairie. These ecosystems supported incredible biodiversity, healthy soils, abundant wildlife, and thriving pollinator populations.
An Endangered Ecosystem
Today, prairie is one of the most endangered ecosystems in North America. Less than 1% of the original tallgrass prairie remains across much of the Midwest, and some states have lost more than 99% of their native prairie due to agriculture, development, and changes in land management. Before settlement, tallgrass prairie stretched across millions of acres from Indiana to the Dakotas. Illinois was once covered by nearly 22 million acres of prairie. Today, less than 0.01% of that original prairie remains in an undisturbed state. Iowa tells a similar story. More than 75% of the state was once prairie, but less than one-tenth of one percent remains today.
As fertile prairie soils were converted to cropland, most native grasslands disappeared. Fire suppression, urban expansion, invasive species, and intensive land use further reduced the remaining remnants. What survives today are often small, isolated pockets along railroad rights-of-way, cemeteries, preserves, and steep areas that escaped the plow. The largest remaining prairie is in the Flint Hills of Kansas which contains approximately two-thirds of the remaining native prairie in the U.S.
These remnants serve as important reminders of what once existed and provide a blueprint for restoration efforts across the Midwest.
The good news is that landowners can play an important role in bringing prairie back. With proper planning, site preparation, and long-term maintenance, a prairie planting can provide lasting benefits for wildlife, soil health, water quality, and the overall value of your property. Whether you’re establishing prairie through the Conservation Reserve Program (CRP) or creating habitat on your own, understanding the process is the key to success.
Why Prairies Matter
Prairies are much more than fields of grass and wildflowers. They are highly complex ecosystems made up of dozens, and sometimes hundreds, of native plant species.
A healthy prairie provides benefits to the land and habitat that cannot be easily achieved in other ways.
Exceptional Wildlife Habitat
Native prairie offers food, nesting cover, and shelter for a wide variety of wildlife. Pheasants, quail, meadowlarks, bobolinks, deer, rabbits, and countless other species depend on grassland habitat at some point during their life cycle.
Grasslandbirds have experienced some of the steepest population declines of any bird group in North America, largely because native grasslands have disappeared. According to the Illinois Department of Natural Resources, pheasant populations in Illinois have fallen by 84% since the 1990’s. Iowa and Missouri have seen similar declines while Kansas numbers fluctuate greatly due to weather and expiring Conservation Reserve Program enrolled acres. Restoring prairie helps slow or reverse this decline by creating critical nesting and brood-rearing habitat.
Pollinator Benefits
Prairies support an incredible diversity of pollinators, including native bees, butterflies, moths, beetles, and other beneficial insects.
Unlike traditional landscapes that may only bloom for a short period, a well-designed prairie mix provides flowers from spring through fall. This continuous food source helps sustain pollinators throughout the growing season.
Species such as milkweed, coneflower, blazing star, black-eyed Susan, and native asters provide critical resources for monarch butterflies and many native bee species.
Improved Soil Health
One of the most impressive features of prairie plants is what happens below ground.
Many native grasses develop root systems extending six to ten feet deep, with some reaching even farther. These deep roots:
- Improve soil structure
- Increase organic matter
- Reduce erosion
- Improve water infiltration
- Increase drought resilience
- Store carbon in the soil
In many ways, prairie acts as nature’s soil-building system.
Water Quality Protection
Native vegetation slows runoff and helps filter sediment and nutrients before they enter streams, ponds, and rivers.
Research has shown that incorporating native prairie vegetation into agricultural landscapes can dramatically reduce soil erosion and nutrient loss while improving overall water quality.
Start Small and Build Over Time
One of the biggest misconceptions about prairie establishment is that it requires hundreds of acres. In reality, even small prairie plantings can make a significant impact.
Landowners can start by converting:
- Field corners
- Low-yield crop acres
- Filter strips
- Pond edges
- Hillsides
- Hunting food plot borders
- Rural home acreages
Many successful prairie projects begin with just a few acres and expand over time. Less than one acres is helpful for plant diversity and attracting pollinators. One to five acres is beneficial nesting cover for grassland birds while greater than five acres makes a significant improvement for wildlife.
If budget is a concern, consider planting a simple native grass mix first and adding additional forbs and wildflowers through overseeding in future years.
The important thing is getting started today for all species to benefit in years to come.
