How did controlled burning change the landscapes used by Indigenous peoples of the American Southeast?

Indigenous peoples of the American Southeast significantly altered their environment through the controlled use of fire, a practice that served as a vital tool for landscape management.1

By regularly burning the forest understory, these groups achieved several ecological and subsistence goals:

• Creating Secondary Growth: Controlled burning cleared dense undergrowth, which encouraged the development of secondary-growth flora. This environment favored the growth of berry bushes and other useful plants.1
• Supporting Wildlife: The resulting mosaic of forest openings and edges provided essential habitats for game animals, including deer, squirrels, rabbits, and wild turkeys, which were primary food sources for the population.1
• Enhancing Resource Production: Fire was used to maintain stands of fire-tolerant species, such as oak. By reducing competition and increasing sunlight exposure, these fires encouraged greater nut production.2
• Facilitating Movement: Beyond subsistence, fire was used to keep forests open, which made the landscape easier to traverse for hunting and travel.3

These environmental modifications allowed Indigenous groups to maintain a productive balance with nature, supporting large populations through a combination of hunting and agriculture.1
