The plants and animals of the prairie ecosystem are
adapted to fire, and thrive with it as part of their life cycle.
The above-ground parts of grasses die every fall, creating thatch that
keeps the ground cool and moist. But, in the spring plants need light
and heat. Fire recycles nutrients from the thatch into the soil,
so other plants can use them. In the spring, fire-blackened soil
warms quickly, which helps plants get an early start.
To restore prairie landscape at the Neal Smith National Wildlife Refuge,
staff are imitating natural prairie fire. Prescribed burns
are carefully planned and controlled. Refuge biologists prepare
fire management plans tailored to the needs of each restoration area on
the Refuge. Only a few days after a fire, the ground begins to green
up. A burn helps native prairie plants grow, and kills trees,
shrubs, and exotic plants.
