Prescribed Burns

  • Those are the results of prescribed burns (also called controlled burns), an essential practice for restoring and maintaining healthy natural areas at the Arboretum. Trained stewards use safe techniques to burn dead stalks and undergrowth. This practice is essential to the health of native plants and the birds and other wildlife that depend on them. Forests managed with controlled burns are not only healthier, but safer. Without periodic controlled burns, dry, dead undergrowth builds up and eventually can provide fuel for dangerous forest fires.

  • Small areas are burned at a time in a very controlled way. The stewards who conduct the burns are highly trained and use special safety equipment. A technician uses a special torch to burn away the undergrowth in a small area, while others help extinguish the fire as soon as it is safe and has done its work. The flames stay low and contained. Ideally, the fires go out by themselves, but technicians are always nearby to douse them if needed.

  • Burns are only conducted when the weather is appropriate, with no high winds to spread the fire or blow smoke off the site. Arboretum guests do not have access to areas with active burns. Every controlled burn at the Arboretum has the required permits.

  • The Environmental Protection Agency has found that smoke from prescribed burns has no significant effect on air quality.

  • Prescribed burns are done only when there is dead, dried plant material that is not wet from rain or snow. Most burns are undertaken in early spring, when dead stalks and leaves are still on the ground but spring rains have not yet started. Some are done in autumn, after trees’ leaves have fallen but before it snows. Burns are only done on days with little wind, when no rain or snow is forecast.

  • Fire is a normal part of the life cycle of natural ecosystems in many areas of the United States. Before non-Native settlers inhabited the Midwest, Indigenous Peoples used fire to burn prairies and woodlands. Non-Native settlers, however, did not use fire, which allowed invasive plants and other woody vegetation to grow thick in natural areas beginning in the late 1800s. In the last half-century, scientists who study ecology have come to understand how crucial fire is to maintaining prairie and oak-dominated woodland ecosystems. The Arboretum recognizes the importance of Indigenous ecological knowledge and seeks to better incorporate it into its work and understanding of this landscape.

  • The Arboretum has been conducting controlled burns on the prairie since the 1960s and throughout its other natural areas, including woodlands, since the 1980s.

  • Burns help control many weedy and invasive plants that compete with native plants. In spring, the black soil that is left after a burn absorbs sunlight and warms up quickly, so seeds can germinate and native plants can start growing. The ash from burned plants recycle nutrients back to the soil.

  • Within two to three weeks in spring, prairie plants will sprout and grow back taller, more vigorous, and often with more flowers. When a prescribed burn is done on the forest floor, wildflowers are usually more abundant the next spring. If you look closely, you may see evidence of fire, such as lightly charred fallen logs, but in general, burns make the woods and the prairie more green and beautiful.

  • The fire consumes only the dried-out top growth, which has already died. The roots and growing points of the plants are still alive, safe underground, ready to sprout once the ground is cleared by the fire. Since these native plants evolved with fire, they are well adapted to regular burning. Some plants’ seeds even need fire to sprout.

  • Oak trees, which dominate our woodlands, have thick, fire-resistant bark and tolerate fires as a normal part of their life cycle. Controlled burns in the woods do burn away many small tree seedlings, but this helps keep the woodlands open and filled with sunlight, which helps other saplings grow. Burning conserves the forest ecosystem overall.

  • Prescribed burning is a fundamental and widespread practice for managing natural areas. Burns are conducted in many state and national parks, forest preserves, national forests, and other natural areas.

  • The Arboretum offers classes through its Natural Areas Conservation Training (N-ACT) Program.
