An Evaluation of Cover Type as a Predictor of Soil Surface Roughness in a Semi-Arid Grassland.

Abstract

Sites dominated by perennial grasses were significantly rougher than sites dominated by ephemerals and the the character of the surface cover did not explain the variation in surface roughness at most sites. Rougher sites dominated by grasses have a greater water storage capacity, enhanced and are probably more biologically active than sites dominated by ephemerals.
