Short Time Impact of Enclosure on Vegetation Cover, Productivity and some Physical and Chemical Soil Properties
G. Hosseinzadeh, H. Jalilvand and R. Tamartash

Abstract:
Since the vegetation cover and soil characteristics impose a significant effect on performing a proper integrated management in rangeland ecosystems. We evaluated the changes of vegetation cover and soil characteristics under different grazing treatments in Eskelimroud basin located at west part of Savadkouh (Mazandaran province in Iran). Three adjacent areas under different grazing intensities including critical, key and enclosure (reference) had been selected. Statistical analysis of variance and group mean comparison showed that the enclosure area was mostly covered by vegetations of class I while dominant vegetation covers in the key and critical areas were covered by class II and class III types, respectively. These findings showed that increasing of grazing intensity, palatable species had been gradually replaced by unpalatable species, but in the reference area Graminea and palatable forbs was dominantly covered. Crown cover percentage and productivity was significantly differed at the 1% level between the reference and grazing areas. Analysis of variance of soil data showed that soil in reference area was mainly covered by dense herbaceous species containing more amounts of organic matter, nitrogen, electric conductivity, phosphorus and potassium as compared with grazing areas. In fact, it can be concluded that short term enclosure of vegetation cover and soil quality in Eskelimroud basin was due to its adequate rainfall and climate condition.
