Natural resource managers start a prescribed prairie burn in a restored tallgrass prairie in Central Ohio. Used as a management technique, controlled burns mimic natural fire processes, which allow prairies to thrive by inhibiting many invasive annual weeds, stopping growth of invading native tree and shrub species, returning critical nutrients to the soil, and stimulating germination by allowing the sun to warm the soil. Such burns are usually performed in the early spring before most prairie perennial forbs and grasses green up, utilizing accumulated dead vegetation as fuel. The native tallgrass prairie ecosystem has been mostly lost to use of land for agriculture in the United States, with less than 5% of native prairie surviving.
