To keep invading trees out.
In Illinois, the seven types of prairies include tallgrass prairies, wet prairies, dry prairies, mesic prairies, sand prairies, limestone prairies, and shortgrass prairies. Tallgrass prairies are characterized by rich soils and diverse plant life, while wet prairies are found in low-lying areas with saturated soils. Dry prairies thrive in well-drained, sandy soils, and mesic prairies exist in intermediate moisture conditions. Sand prairies are specifically located in sandy areas, limestone prairies are associated with calcareous soils, and shortgrass prairies have shorter vegetation and are less common in the state.
Usually lightning caused fires. In reality the fires were good for the prairies because the grass seeds were released. Some Native American tribes would start fires to move the buffalo toward them so they could hunt them.

it is called the prairies
In prairies, fields, or dry open deciduous woods.
you put out camp fires and do not set fires near dry brush
For a bad, dry cough.
The central lowland region is primarily tall-grassland prairies due to its fertile soils, periodic fires that maintain the grasslands, and optimal growing conditions for grass species like big bluestem and switchgrass. The region's climate also supports the growth of grasses over trees, creating the ideal conditions for prairies to thrive.
Dry weather doesnt cause a fire but it does contribute to the conditions that a fire needs. Lightning strikes cause most fires in dry weatrher. Carelessness of campfires and cigarette butts are other sources as well.
Some fires in the desert are caused by lightening, especially dry lightening. However, many fires are caused by the carelessness of man.

Fires are important to prairies because they help maintain the ecosystem by controlling invasive species, promoting nutrient cycling, and stimulating the growth of native grasses and forbs. The periodic burning encourages biodiversity and helps prevent tree encroachment. In contrast, dunes are typically shaped by wind and water processes, and fire can disrupt the delicate balance of their ecosystems, which often rely on specific plant adaptations to survive in harsh conditions. Thus, while fire plays a crucial role in prairies, it is generally detrimental to dune ecosystems.
