Prairie: a living sea of grass

Wide skies. Deep roots. A landscape alive with flowers, insects, birds, and the movement of wind. A prairie is far more than an empty field—and the closer you look, the more it reveals.

What makes a prairie?

Prairies are grasslands shaped by climate, soils, grazing, and fire. Grasses and other nonwoody plants dominate, with comparatively few trees. Wildflowers—often called forbs—are part of that community, not an exception to it.
A lawn, hayfield, or abandoned farm field may be grassy without being native prairie. The mix of species, the soil’s history, and the ecological processes still at work all matter.

Look beyond the flowers

Notice the height and texture of the grasses. Listen for birds calling from low perches. Look for insects visiting blossoms—and for the subtle changes between a dry rise and a damp hollow.

Who lives in the prairie?

A prairie provides food, shelter and nesting places from the soil to the seed heads. These animals are familiar examples from Midwestern grasslands and their edges. Some rely strongly on grassland; others move between prairie, brush and woodland. Brian’s photographs show the animals, not necessarily a prairie setting in every image.

Below ground: burrows & shelter

Thirteen-lined Ground Squirrel

Short grass & underground shelter. This striped ground squirrel feeds on seeds, plants and insects. It favors low vegetation where it can see approaching danger, and uses burrows for shelter, nesting and hibernation.

Groundhog

A prairie-edge neighbor. Also called a woodchuck, this plant-eater uses burrows and often lives near brushy margins, woodland edges and fields. It can visit prairie edges, but is not a grassland specialist.

Two homes beneath the prairie

Both animals can have multiple entrances and both hibernate. Ground squirrels use narrow tunnels; groundhogs excavate larger burrows with a nest and separate latrine.

Layouts vary. The squirrel illustration combines nesting and winter features for comparison; these may occur in separate burrows.

Simplified cutaways show two connected surface entrances in both a thirteen-lined ground squirrel’s narrow burrow and a groundhog’s larger burrow, with labeled underground chambers.
Simplified examples—not to scale. Burrow layouts and depths vary.

Among the grasses: hunters & browsers

Coyote

A hunter among the grasses. Coyotes search open country for rodents and other small animals, connecting prairie prey with larger predators. They are adaptable residents of many habitats. Brian photographed this one at Midewin National Tallgrass Prairie.

White-tailed Deer

Feeding in openings, sheltering in cover. Deer eat a variety of plants and move between grassy openings, brush and woods. They use prairie landscapes without depending on prairie alone. Look for ears rising above tall vegetation.

Above the prairie: songs & flight

Birds may sing above the grass while nesting or feeding much closer to the ground. A prairie’s vegetation provides more than a perch.

Eastern Meadowlark

A grassland voice. Listen for its clear song from a raised perch. Meadowlarks feed on the ground and conceal their nests among grasses, so the living space below the song perch matters too.

Bobolink

A summer grassland visitor. Bobolinks nest on the ground in grassy habitat. The male’s black-and-white breeding plumage and pale nape stand out above the vegetation. Brian photographed this bird at Glacial Park.

Dickcissel

Song from a sturdy stem. This grassland bird uses prairies, restored grasslands and other open habitats. Listen for its name-like song and look for a singing bird perched above the grasses. Its numbers can vary noticeably from year to year.

Try this on your next walk: pause and listen before moving on. Watch from the trail for a song perch, moving grass or a burrow entrance. Give nests and burrows space.

Tallgrass, mixed-grass & shortgrass

Across the Great Plains, rainfall generally decreases from east to west. Prairie vegetation responds to that broad gradient, although soils, slope, weather, and management create many local exceptions. These are ecological regions, not three neatly separated strips.

The person provides a consistent visual reference, not a measured height scale. Select the illustration for a closer look.

Three prairie landscapes with the same person for scale: tallgrass is generally wetter and taller, mixed-grass intermediate, and shortgrass generally drier and shorter.
A simplified comparison: vegetation height and rainfall vary by place.

Tallgrass

GENERALLY WETTER · EASTERN PRAIRIE
Big bluestem, Indian grass, and switchgrass can tower above a person in favorable conditions. Tallgrass prairie is especially associated with the eastern Great Plains and Midwest.
Picture it: tall grasses threaded with milkweeds, coneflowers, and other wildflowers.

Mixed-grass

A TRANSITION · CENTRAL PLAINS
Shorter and taller grasses grow together. Their proportions change with soil moisture, terrain, and grazing. A mixed-grass landscape can look very different from one slope to the next.
Explore an example: Badlands National Park in South Dakota.

Shortgrass

GENERALLY DRIER · WESTERN PLAINS
Low-growing grasses such as blue grama and buffalograss are characteristic of the drier western plains. Shortgrass prairie is not simply tallgrass prairie that has been cut short.
Explore an example: Colorado’s Pawnee National Grassland.

Meet the grasses

Big Bluestem: a close look at its fingerlike flower head.

Big Bluestem helps give tallgrass prairie its height and structure. Its small flowers are easy to miss until you look closely at the branching heads.

Grass flowers deserve a closer look

The dangling structures are anthers, which release pollen. A prairie is full of flowers even when its most noticeable colors come from grasses.

A prairie is a mixture

Mixed prairie grasses at Scuppernong Prairie, Wisconsin.

Big Bluestem and Little Bluestem can grow together, alongside other grasses and wildflowers. These photographs show a mixed plant community rather than a stand identified as one species. Changes in soil, moisture and management help create the patchwork.

Look closely at the community

Mixed prairie grasses: a closer view of the stems.

A wide view shows the structure of a grassland; a closer view reveals overlapping stems and seed heads. To identify a particular grass, follow one stem to its complete flowering head instead of assuming everything nearby is the same species.

Dry, mesic & wet: another way to describe prairie

Grass-height regions describe a broad pattern. Dry, mesic, and wet describe local moisture conditions. Both labels can apply to the same place: a tallgrass region can contain dry prairie, mesic prairie, and wet prairie.
Dry prairie: water drains away readily or soils hold relatively little moisture; sandy ground, shallow soils, and exposed slopes can contribute.

Mesic prairie: moderately moist conditions—neither especially dry nor persistently wet.

Wet prairie: a high water table or seasonal saturation favors plants able to tolerate wet ground.
Sand, gravel, dolomite, and other substrates add further variety. A short walk can cross several plant communities.

Prairie and marsh meet at Goose Lake Prairie. A landscape can contain several communities side by side.
Open water in this photograph is marsh habitat; it is not what defines every wet prairie.

From dry hilltop to wet hollow

A short walk can cross dry hilltops, moderately moist ground and seasonally wet hollows. Soil and drainage shape the plants you find; this is one possible pattern.

A prairie slope transitions from rocky dry ground through moderately moist mesic prairie to a low wet hollow, with changing grasses and wildflowers.
One possible moisture gradient; soils, drainage and plant communities vary.

Fire is part of the prairie story

A burned prairie can look lifeless at first. Yet many prairie plants keep protected growing points at or below the ground. As conditions allow, shoots emerge again. Fire can help maintain the open, sunny conditions on which prairie communities depend.

From old growth to new shoots

Follow the sequence from accumulated litter to a planned burn, emerging shoots and later flowers. Removing old vegetation can let more sunlight reach new growth.

Recovery depends on the season, moisture and burn conditions. Trained crews plan prescribed burns around the needs of the whole community.

NPS: fire and prairie growth

Four illustrated stages show thick dead grass shading shoots, a prescribed fire removing litter, early regrowth in sunlight, and a later flowering prairie.
A simplified sequence over time; recovery depends on season, moisture and burn conditions.

Keep sunlight on the ground

Fire removes accumulated dead vegetation and can check the spread of woody plants. That opens space and light for prairie plants. The response depends on the species present and the timing and intensity of the burn.

Work with grazing

Grazers respond to new growth after fire. Their feeding can create a patchwork of vegetation heights, rather than one uniform grassland. Bison, fire, and diverse plant communities are connected parts of the story.

Plan for the whole community

Prescribed fire follows a site-specific plan carried out by trained crews. Managers consider weather, fuels, plants, wildlife, and conservation goals. More fire is not automatically better, and one schedule does not fit every prairie.
Indigenous peoples have long used fire to shape and care for grasslands. Lightning-caused fire also played a role. Today’s prairie stewardship draws on ecological research and land-management experience; it is an ongoing process, not a one-time treatment.

The prairie beneath your feet

Much of a prairie’s living structure is hidden. Roots, rhizomes, and other underground organs help perennial plants take up water, store energy, and regrow. Root systems vary: some reach deeply, while others form dense networks nearer the surface.
These living roots and the soil community help stabilize the ground and support the cycling of water and nutrients. Protecting prairie means protecting the soil as well as the flowers.

A remnant cannot simply be replaced

A remnant retains native prairie from an earlier landscape. A restoration improves a degraded community. A reconstruction re-establishes prairie vegetation where it was removed, often on former cropland.
All can contribute to conservation, but newly planted acres do not instantly recreate the soil history and full community of an old remnant.

How much prairie is left?

There is no useful single count of “large prairies” without first defining large, deciding which prairie types to include, and separating intact remnants from restored land and broader ranching landscapes. The examples below are a selection—not a national inventory.

Less than 4%

The National Park Service estimates that less than 4% of the original North American tallgrass prairie remains intact, much of it in the Flint Hills.
This is a tallgrass estimate for North America, not the share of all U.S. prairies remaining.

Large western landscapes

Substantial native grassland landscapes still survive. Nebraska’s Sandhills are among the country’s largest remaining intact grassland systems, including working ranchlands.
A broad region is not the same thing as one protected preserve.

Remnants + recovery

In much of the Midwest, conservation connects small surviving remnants with restored areas. Nachusa Grasslands is one example: more than 4,000 acres include both remnant and restored prairie.
Site acreage should not be read as the acreage of untouched prairie.

The Black Belt: a southern prairie surprise

Prairies are not confined to the Great Plains. The Black Belt curves through Mississippi and Alabama, where chalk-derived soils support a distinctive mosaic of prairie, chalk outcrops, and woodland. Its open plant communities include grasses and wildflowers familiar from farther west, alongside regional specialties.
Its name refers to the region’s dark, fertile soils. Those soils also made it attractive for agriculture. NASA’s 2018 account reported that less than 1% of the prairie documented there in the 1830s remained—a historical estimate, not a new 2026 survey.
Pulliam Prairie is one significant Mississippi remnant. Other pieces survive as scattered patches, and restoration programs work with landowners to expand habitat. The whole Black Belt is not intact prairie today.
Two different names: Black Belt Prairie = Mississippi and Alabama. Blackland Prairie = a separate regional prairie system in Texas.

One prairie, four seasons

These are things to watch for on a Midwestern prairie. Timing changes with latitude, rainfall, and the species present; a prairie does not need to be in peak bloom to be worth visiting.

Return to the same spot through the year and compare what changes. Select the illustration to enlarge it.

The same prairie view in spring, summer, fall and winter shows fresh shoots, flowering vegetation, ripening seed heads and standing stems above snow.
A simplified Midwestern example; timing and species vary by place and year.

Spring

Look low. Early flowers can bloom while last year’s stems still stand above them. Compare fresh shoots with the old seed heads.

Summer

Watch flower visitors and listen for birds. As grasses rise, the prairie becomes a layered world of leaves, stems, and blooms.

Fall

Notice seed textures and changing grass colors. Look for late flowers and watch how wind moves seeds through the landscape.

Winter

Read the structure: standing stems, seed heads, and animal tracks. Many perennial plants persist below ground while dried vegetation remains above.

Try a five-minute prairie challenge

Try this at any prairie. Pause at one spot along the trail. How many can you notice?

  1. Three grass shapes: compare leaves or seed heads without picking them.
  2. A flower visitor: watch an insect approach or land on a blossom.
  3. A sign of animal life: look for tracks, a distant burrow entrance, or moving stems—or listen for a bird.

No flowers today? Look for three different seed heads instead. Observe from the trail and give wildlife space.

Help protect prairies

  • Stay on designated trails. Enjoy a closer view with binoculars or a camera zoom.
  • Leave plants and seeds where they grow. Take photographs and observations home.
  • Support local restoration. Join an organized volunteer workday or support a prairie preserve or conservation group.

Follow each preserve’s visitor guidance and respect restoration closures.
