Account A: A Blog Post by Teresa Vang, Burn Crew Leader at Tallgrass Hills Prairie Preserve
1Last Saturday morning, our crew carried out the spring burn on the east field of Tallgrass Hills Prairie Preserve. We had planned this day for months. A safe burn needs the right weather: a gentle, steady wind and grass that is dry, but not too dry. When the forecast finally matched our plan, we posted a notice on our web page and at the town hall.
2Before we lit a single flame, our crew mowed a wide strip around the field. This strip, called a firebreak, has very little grass left to burn, so the fire stops when it reaches the strip. Two water trucks waited nearby, and every crew member wore fire-resistant clothing. We lit the fire at nine o'clock, and by two o'clock the whole field was black. Around noon, the wind shifted for a short time and carried some smoke toward Elm Road.
3Why burn a prairie at all? Prairies need fire to stay healthy. Long ago, fires started by lightning and fires set by Native American peoples swept across the prairies. Many prairie plants have roots that reach deep underground, where the heat cannot harm them. Fire clears away old, dead grass so that sunlight can warm the soil, and it stops young trees and shrubs from taking over. In a few weeks, bright green shoots will cover the black ground. Come see them for yourself!
