Fire can be incredibly destructive in nature. However, it is also an integral part of the tallgrass prairie ecosystem. Over thousands of years, this ecosystem adapted to drought and fire and became dependent on it.

Historically, some prairie fires started due to lightning, and others started because American Indians used fire for hunting bison and making travel easier. Burning prairies in the fall caused plants to grow earlier in the spring. This attracted grazing bison.

Frequent fires slow down the invasion of trees and shrubs from the edge of the prairie. This maintains the grasslands and treeless structure of the prairie. Fires also burn up old plant litter, release nutrients into the ground and expose soils that warm faster in the spring. Warm soils increase seed germination and growth of prairie grasses.

Prairie plants survive fires because 50 to 80 percent of the plant is underground. Plants can quickly re-grow using energy and nutrients stored in their undamaged roots.

American Indians and European settlers feared prairie wildfires In dry, windy weather, these fires spread

Prairies Still Need Fire
Fire is still an important tool in managing remnants of original tallgrass prairie and newly restored prairies. Wildfires of the past were often large and could happen at anytime. Today, trained professionals manage controlled burns that are smaller than most wildfires. These controlled burns are conducted during cooler temperatures when wind speeds are lower and the prairie is not too dry.

Despite the risks of fire, many animals and birds thrive in the tallgrass prairie. Behavioral adaptation, such as burrowing underground, keep many smaller animals and some birds safe from fires. Mature birds fly to safety and larger mammals frequently outrun fires. Today's smaller controlled burns create less risk to wildlife and humans.

A glacial land form of rolling hills called Buffalo Ridge rises above the surrounding terrain and stretches 60 miles across the southwest corner of Minnesota.

Tallgrass Prairie
Tallgrass prairie gets its name from some species of grass that reach more than six feet tall by late summer. Some call it an upside-down forest, because roots can reach more than 15 feet underground. This ecosystem boasts more than 900 recorded plant species.

Prairie plants massive root systems can stay alive for decades, and the prairie is always changing. In spring, the shorter plants bloom while the taller plants sprout. In summer, Carly season plants die back and tall grasses and flowers dominate the landscape. Non native plants with shallow roots cannot compete with a healthy prairie. An established tallgrass prairie with natural processes such as fire can effectively stop non-native plants from growing.

Some prairie roots extend more than 15 feet underground and provide many environmental benefits. They control erosion, filter water, resist growth of non-native plants and enrich the topsoil when they decompose. These dense root masses also allow the plants to resist the effects of drought.

Prairie ecosystem Tallgrass prairie is one of the most endangered and fragmented ecosystems in North America. It once stretched from Saskatchewan to Mexico and from east of the Mississippi River west to the Central Great Plains.

Before European settlement, this ecosystem covered one-third of Minnesota. Today, only one percent of the state's original tallgrass prairie remains.
