Fire helps maintain healthy prairies and assists with our oak savannah restoration. Fire reduces thatch and helps control spread of weeds and undesirable woody vegetation while putting nutrients back into the soil. Even invasive red cedars can be destroyed when small (1-2 years old and less than 3 feet tall). Prescribed fire promotes the growth and abundance of oak savanna understory or the ground vegetation by rejuvenating native grasses and forbs. Burned habitats quickly respond to warmer temperatures that provide greater forage and improve wildlife habitat.
