AbstractThe Big Burro Mountains in southwest New Mexico has been undergoing a decrease in herbaceous vegetation and an increase in woody vegetation. Through numerous unnamed ephemeral drainages this area contributes a significant amount of sediment into Mangas Creek, which is a tributary of the Gila River. In 2004, a prescribed burn was conducted to remove the woody vegetation and encourage the growth of herbaceous cover vegetation to reduce the amount of hillslope erosion. The Hillslope Erosion Model was utilized to predict sediment yield occurring in both a burned area and a nearby unburned area. Erosion bridges were established onsite to measure sediment yield. A data logging rain gauge was also located at the monitoring site to measure rainfall duration and intensity. Preliminary data indicates that the Hillslope Erosion Model was found to be a reliable tool for predicting hillslope erosion following rain events greater than one inch.
