• Prairie burns discourage weeds and stimulates growth of prairie plants.

• Many plants, species, types of prairies and environmental factors influence how often to burn. Mesic (accumulate litter faster) prairies should burn every 1-3 years. Dry prairies should burn every 4-6 years. More frequent burns may be necessary on weedy prairies.

• Burns should be conducted in March, April or early May.

• Humidity, temperature, wind and rain are important factors in scheduling a burn.

• Fire rejuvenates a prairie- More plants flower, more seeds produce, and plants grow taller and more robust than previous years.

• Serves as a fertilizer- Fire increases nutrients through stimulation of microbial activity in the soil and by releasing small amounts of nutrients from the ash.

• Lengthens the growing season- Most prairie plants grow best in warm soil. Fire burns off leaf litter, exposing a darkened soil surface to the warming rays of the sun, therefore warming up soil, promoting growth. Plants are not damaged by fire because buds lie beneath the ground.

• Fire shortens the growing season for Eurasian weeds, warm soil causes their roots to stop growing.
