چکیده

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.
