Chapter 9: Prescribed Burning

Table of Contents

Flames of a prescribed prairie burn around the outside of a field of prairie grass.
Prescribed burning helps most native prairie plants grow while also aiding in the control of weeds and small trees.

Prescribed fire is an essential component of native vegetation establishment and management. Though there are challenges associated with the process, prescribed burning can be executed safely and effectively in the roadside environment.

Prescribed fire is a management tool used for three main objectives:

  • Discourage the growth of invasive and woody plants.
  • Invigorate the growth of native plants.
  • Remove thatch (including crops that end up in the right-of-way from flooding or wind) and biomass to help open ditches to help with water infiltration.

A timely burn can slow the growth and spread of weeds and small trees, both of which are susceptible to the intense heat of the fire. On the other hand, most native prairie species respond positively to fire. Historically, this ecological relationship was critical to the existence of the tallgrass prairie, and today, it continues to be an essential management practice for roadside prairie remnants and plantings.

The keys to a successful and safe prescribed burn are adequately trained staff, the right equipment, and advanced planning.
