The distinctive historical vegetation pattern of alternating tallgrass prairies on clay soils and oak woodlands/savannas on sandy soils in North Central Texas and East Texas has been described for more than a century. Many authors have attributed this pattern to relatively high levels of soil moisture available for tree growth on areas of sandy soil, and conversely, inadequate levels of soil moisture for tree growth on clay soils. However, this explanation is not consistent with present day observations of rapid invasion of clay soils by woody vegetation. We propose an alternative hypothesis, that the historical distribution of prairies and woodlands in North Central and East Texas can be explained by soil-dependent variations in grass biomass and resulting differences in fire frequency and intensity.
