چکیده

Annual climate fluctuations cause changes in production, condition, trends and grazing capacity of rangelands. The present study investigated effect of climatic factors on the vegetation dynamics in Jashloobar, summer rangeland of Semnan province, Iran, in two vegetation types: Festuca rubra in Margesar and Stipa lessingiana in Sefiddasht during 2011–2015. Climatic parameters included temperature (mean daily, absolute maximum, absolute minimum, monthly maximum and monthly minimum), monthly humidity (absolute maximum, absolute minimum and average) and monthly precipitation. These factors were determined by Inverse Distance Weighted method using 19 meteorological stations in Semnan province due to an absence of climatological and synoptic stations on this site. Vegetation cover percent and production were measured within two 400m transects and 20 plots (1×1m2) along transects. Means comparisons were made between the years in terms of vegetation production and canopy cover using Duncan test, and the relationship between climatic factors with vegetation parameters which were determined using linear regression. Results show that production varies significantly over years (P<0.05). The lowest production rates in Margesar and Sefiddasht were observed in 2013-2014 with 254 and 213.3 kg/ha respectively. Although the precipitation significantly decreased from 293 mm in 2011-2012 to 173 mm in 2013-2014(P<0.05), but stepwise regression indicated that finally in Margesar, absolute maximum temperature and absolute minimum humidity in December and in Sefiddasht, absolute maximum temperature in June and absolute minimum temperature in August were entered in production forecasting model. This indicates that forage production is highly sensitive to absolute mentioned climatic parameters in addition to rainfall. Also, due to short period of growing season in these years, grazing period should also be limited; therefore, ranchers and the government should optimize rangeland management and reduce the length of the grazing period, decreasing grazing capacity or alternative livelihoods such as ecotourism, beekeeping and exploitation of medicinal plants.
