natural ecosystems provide many goods and services for human beings via their multiple functionalities. one of these important functions is the role of natural ecosystems in regulation of hydrologic cycle and increasing the infiltarion and retention of water in soil context and preventing from water runoff which may cause in unfavorable consequences like soil erosion and flooding. quantificatio...

Alto Minho (in northwestern Iberia) is one of the European regions most affected by fires. Many these fires originate from rangeland management Atlantic heathlands, and, while being illegal, often are not actively suppressed. In this study, pastoral (autumn-to-spring unrecorded authorities), spring wildfires, and summer wildfires were independently mapped dated remote sensing. burned at a mean ...

Rangeland degradation is one of the global concerns affecting the pastoralists and those who suffer from its negative environmental consequences. Grazing exclosure has been extensively used among the techniques implemented by the government to protect the fertility of threatened rangelands. The impact of exclosure has been a controversial issue; therefore, it is important to understand its effe...

Soil microbial biomass plays an important role in nutrient transformation in terrestrial ecosystems. Microbial biomass is also an early indicator of changes in total soil organic carbon. Thus, the main objective of this study was to identify and quantify the present status of soil microbial biomass carbon and nitrogen with various management practices in Himalayan rangeland. To meet the aforeme...

Information about the distribution of grass nitrogen (N) concentration is crucial in understanding rangeland vitality and facilitates effective management of wildlife and livestock. A challenge in estimating grass N concentration using remote sensing in savannah ecosystems is that these areas are characterised by heterogeneity in edaphic, topographic and climatic factors. The objective is to te...

In the countries surrounding the Mediterranean basin, most of the semi-natural grazing lands are covered by rangelands. Rangelands can be defined as highly heterogeneous natural vegetation communities with high conservation value, growing in harsh environments (poor soils, unfavourable climatic conditions). In the recent socio-economic context, traditional livestock grazing practices that enabl...

Biodiversity in rangelands is decreasing, due to intense utilization for livestock production and conversion of rangeland into cropland; yet the outlook of rangeland biodiversity has not been considered in view of future global demand for food. Here we assess the impact of future livestock production on the global rangelands area and their biodiversity. First we formalized existing knowledge ab...

ecological studies on range plants enhance our knowledge on the rangeland ecosystems which are useful for their planning and management.  by doing field and laboratory experiments during 2008-2009, ecological conditions were studied in the main habitats of z. atriplicoides in the rural and winter rangelands of northern khorasan province (nkp). forage quality was also studied at different phonol...
