"Historically, a blanket of bison covered the savanna landscape of southeast Texas. Large herds consumed vast quantities of grasses and their hooves disturbed the soil, and dispersed seed. Though the grazing was intense, the bison moved, allowing the savanna time to recover.
Fires regularly spread through the savanna. These fires were typically very large and continued until stopped by a change in topography or storms smothered them. These fires stimulated growth of the grasses and forbs, suppressed invading woody plants and ultimately contributed to the incredible species diversity of the grasslands."
