Soil loss from wildfire in semi-arid grassland

The authors measured the results of a wildfire on soils in a grassland of southwestern Kansas.  They compared burned areas in grassland and shrubland communities to unburned ones.  Soil types were similar across the study.  They found that soil repellency was greater in the shrublands.  Furthermore, greenness (NDVI) in the grassland areas recovered more quickly from the burn and less soil was lost to wind erosion.  This study indicates the value of maintaining grassland communities where shrub encroachment is a threat.
