Frequently asked questions

Prescribed fire is a carefully planned activity, and controlled burns are conducted under specific weather conditions by trained professionals. Many Illinois ecosystems — including prairie, oak savanna and woodland — evolved with periodic fire. Prescribed burning helps:
- Control invasive species
- Encourage native plant growth
- Recycle nutrients
- Maintain healthy ecosystem structure
Burns are conducted with public safety as the top priority.
Sites are prioritized based on ecological quality, presence of rare species or communities, restoration potential and their importance in supporting larger landscape-level conservation goals. Protecting and buffering the best remaining natural areas ensures the greatest long-term ecological benefit.
