H istorically, fires set by lightning and American Indians kept the prairies from becoming brushlands and forests.
Fire kills the above ground parts of shrubs and small trees.
Prairie plants grow more vigorously when built-up plant materials and shade are removed. Spring fire uncovers the soil, so it warms sooner, thus extending the growing season. Prescribed fire is a carefully planned and controlled fire conducted to manage natural areas such as prairie, oak savanna, wetlands and oak woodlands. It is conducted only under safe conditions. Prescribed fire initially requires experienced help, plus a good working relationship with neighbors and the local fire department.
