متن کاملStudying Short-Time Dynamics of Vegetation and Soil Organic Carbon in a Semi-arid Rangeland (Case Study: Zharf, Khorasan Province, Iran)
Abstract. Rangeland vegetation dynamics encompass all processes of changes in vegetation composition and structure over time. Investigating the rangeland ecosystem dynamics makes it possible to determine the effects of climatic and management conditions on qualitative and quantitative changes of the vegetation in a specific period of time. Accordingly, data collection and measurements for evalu...
متن کاملRangeland management and animal production sustainability under arid and semi arid conditions: Egypt overview
Livestock fodder needs in nearly all developing countries now exceed the sustainable yield of rangelands and other forage resources. In Africa, overgrazing has reduced range productivity virtually everywhere. It is important to provide animals with adequate nutrition to ensure the high productive and reproductive performance. Meanwhile, it is necessary to avoid the deterioration of the pasturel...
متن کاملThe effects of exclosure on plants in the semi-arid rangeland of North Khorasan province, Iran
Abstract Over the last fifty years, most of the semi-arid rangeland in Iran has been converted to cropland without an equivalent reduction in grazing animals. This shift has led to heavy grazing pressure on rangeland vegetation. The present study has been conducted in Sisab Research Station in the North Khorasan Province to evaluate effects of long-term grazing exclosures on biodiversity of ra...
