Iowa

Home of the

Prairie

Two hundred years ago, most of

Iowa was a tall grass prairie.

Prairie grasses and flowers

made up about 85 percent

of Iowa’s countryside.

Plants and animals lived and

thrived in the prairie ecosystem.

Plants are the primary producers

of food in the prairie food chain.

Insects and small mammals like

rabbits and mice ate the flowers

and grasses.

Predators like coyotes, snakes

and hawks ate the plant eaters.

Sitting at the top of the food

chain were cougars, bears and

wolves.

Scavengers and decomposers like

vultures and earthworms broke

down dead plants and animals.

Plants and animals formed a

healthy prairie community for

many years.

During the 1800s, people began

to settle in Iowa. Unfortunately,

this began to upset the stability

of the prairie.

European settlers plowed up

much of the prairie and turned

Iowa’s rich soil into farmland.

Also, there were no restrictions

on hunting at the time so some

animals became scarce and that

also upset nature’s balance.

Iowa’s woodlands and wetlands

also suffered, but the prairies

were the most affected.

Without the plants, other

members of the prairie

food chain had to find

new homes or face extinction.

Herds of buffalo would no longer

roam freely through Iowa’s tall

grass prairie.

Of the 30 million acres in Iowa

that once were covered in

prairie, less than 1/10th of 1%

remains.

Fortunately, there is something

we all can do about it.

Today, many individuals and

groups are working to preserve

and restore prairies in Iowa.

Prairie grasses and flowers are

popping up along Iowa’s

roadsides.

State and county workers are

planting grasses and prairie

flowers in roadside ditches.

They are using the native plants

to stop soil erosion and eliminate

pesky weeds.

By restoring prairie land in Iowa,

we improve the health of our

environment.

These and other remaining

prairie wildlife areas are home to

insects that pollinate the crops

and birds that control other

problem insects.

The roadside prairies offer

beauty as well as more habitat

for wildlife.

Native Iowa plants with their

deep root systems increase soil

fertility and stability.

People are working to preserve

prairies around the state, such

as at Loess Hills in western Iowa.

Other people are starting prairie

plots at schools or in their own

backyards.

You can make a difference.
