Infiltration rate and sediment production were observed over two years in Texas in an intensive rotational grazing system. Midgrass-dominated interspaces were characterized by significantly higher infiltration rates and lower sediment production than shortgrass-dominated interspaces. Infiltration rate declined and sediment production increased following the short-term intense grazing periods inherent in the rotational system. The most important factor in this study was that the most negative impacts to the soils hydrologic condition occurred during the dormant season, rather than in the growing season. The authors recommend that riparian areas receive lower stocking rates or longer periods of rest during the dormant season in order for those areas to recover to a healthy hydrologic condition.
