Abstract

RANGELAND EXCLUSION to livestock is one of the management methods for range management as well as WATERSHED MANAGEMENT that are applied for range rehabilitation and improvement. This management is used for increase in VEGETATION COVER in watershed area that leads to increase in amount of land cover and consequently, causing stabilization of soil, reduction of soil loss rate and SEDIMENT YIELD. In order to determine quantitative effect of RANGELAND EXCLUSION to livestock on reduction of rainfall loss in terms of SURFACE RUN-OFF, soil loss (i.e. soil EROSION) and SEDIMENT YIELD, The five years excluded rangeland on Raeis-Ali Dam watershed locating in Dastestan Districk of Boshehr Province – Iran, was selected as the study area and amount of VEGETATION COVER, SURFACE RUN-OFF depth and amount of SEDIMENT YIELD were studied. The needed data were collected of homogenous units both in the excluded rangeland as a treated area and in the no tread rangeland as a control area. Explanatory and statistical methods were applied to analyze data (i.e. t- student test and correlation analyses between depth of SURFACE RUN-OFF and amount of SEDIMENT YIELD with VEGETATION COVER changes). Results of the study are shown that there is significant deference between VEGETATION COVER density in excluded rangeland and control rangeland. Negative correlation between amount of VEGETATION COVER and depth of run-off SEDIMENT YIELD rate (r = 0.92 and r = 0.84 respectively, a= 0.01) indicates that there is a significant relationship between exclusion of rangelands with decrease in soil loss and SEDIMENT YIELD rate as well as SURFACE RUN-OFF loss on rangelands. Thus, it can be concluded that RANGELAND EXCLUSION to livestock is a simple and low cost management program for rehabilitation and improvement of rangelands if and only if socio-economic problems could be resolve properly. Therefore, this management method can be considered as a workable method for solving soil EROSION and SEDIMENT YIELD problems and achieving to the goals and objectives of SOIL CONSERVATION and WATERSHED MANAGEMENT program.
