Abstract :

Abstract More than the half of Iran area included rangelands that are as important as an economic and social revolution bed of Iran tribes. Vegetation determination and rangeland statue detection using recognized methods help us for optimum using and destruction prevent and needed balance consideration of rangeland. Ala region of Semnan is considerable as a rangeland in order to great area and species rich that in this study was investigated. In this study vegetation map and floristic list of region was prepared using satellite images and geographical information system and desert visits and we use 4 factors method for rangeland statue analysis. In this study at the first working unit were provided in 3907.4 area for vegetation research of Ala region. Major rangeland species of each type for each working unit were identified based on regulated tables and forms and the type name was determined according to medium dominance of canopy. There dominant plant type was detected in this region included Artemisia, Holxylon and Peganum. The results show that rangeland statue in studied region is poor with considering measuring and estimations and tendency go toward retro gradation. So in this rangeland the management methods and their applying methods are so important.
