Abstract :
The effects of Range Management Plans (RMP) on soil and vegetation characteristics were studied in Eshtehard rangelands at Alborz province. The parameters of yield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%), Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sites of Ghenzel Cheshmeh as RMP and sanctum of Rahmanyeh village. The data were analyzed using T- test. The results showed that due to the reduction of plant species in the arid and semi-arid areas and the need for vegetation change for long time, the difference of canopy percentage between two sites were not significant but implementation of rangeland management plan increased the yield and improved range condition and trend. RMP had increased the N and OM% of the soils and decreased P, K and bulk density.
