Effect of management and rangeland's area on vegetative characteristics (case study: Taleghan watershed)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 7
Abstract
Property rights are one of the main tools to achieve sustainable development and natural resource management which encourage the owners to continue their ownership. In Iran, range management plans are considered as one of the main tools for management and utilization of rangelands and also establishment of owners' rights. In this research, effects of property type and rangeland's area on vegetation and soil factors were studied. Twelve summer rangelands of Taleghan watershed were investigated. Rangelands were selected as two types of management (rural and collective) and three areas of 0-550 ha, 550-1100 ha and more than 1100 ha were included. In each rangeland, Physiognomic-Floristic method was applied to determine the vegetation types. Area of the sampling quadrates was calculated based on the minimal area method and number of quadrates was statistically determined with regard to the variations of the vegetation. In each unit, sampling was carried out along with three transects with a length of 150 m. Fifteen quadrates of 1m2 with intervals of 10 m were established on each transact and vegetation and soil factors were evaluated at the time of range readiness. All collected data were statistically analyzed by SPSS software based upon factor analysis and factorial experiment in a completely randomized design. According to the results, a better condition was identified for vegetative factors in rural rangelands and also in those categorized in an area of more than 1100 ha compared to the collective rangelands and those with an area of 0-550 ha, 550-1100 ha.
