Since Renaissance, the natural ecosystems have fallen into a complete state of disarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of the major sources of carbon storage, and plays a paramount role in the global equilibrium of carbon as well as carbon sequestration. Given that Iran […]
The study of the exclosure effects on the vegetation changes under grazing and non-grazing conditions in the rangeland areas has particular importance in the rangeland improvement and revivification projects. The research was accomplished in semi-steppe KhoyBilehvar area, from 1999 to 2005. Vegetation cover was annually measured within fixed plots during transact. The results showed that […]
Overgrazing, via harvesting of forage species and decrease the other herbs, is of progressive factors in biodiversity destroying. In order to investigate the animal grazing impacts on changing of plant structure and diversity, we selected the comparison between this effect with exclosure area, and proving of the excluded area effects on plant diversity; two sites […]
Studies on vegetation changes of rangelands under grazed and non-grazed conditions are of great importance in the range management planning programs. To determine the change process of vegetation, this study was performed in Inche Shorezar site of Golestan province for nine years (1997-2005). The vegetation parameters were measured every year in several fixed plots inside […]
The range conditions explain its health as a management tool. Obviously, the implementation of this important assessment requires the most appropriate study method for each region. In order to select the most appropriate methods of range conditions in Kabirkooh grasslands of Zagros in Iran, five estimation methods (i.e. six-factor, fourfactor, vegetation and soil combination, value […]
In recent years, rangelands have been regarded as potential carbon sinks. One of the most widely suggested options to sequester more C in rangelands is the restoration of the degraded rangelands through grazing the exclusion. In present study, the effects of exclusion on the carbon sequestration of Gomishan rangelands were investigated. Three transects were established […]
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 […]
The Naâma steppe rangelands in Algeria are undergoing continuous degradation due to overgrazing, land clearing, silting up and desertification. Given the seriousness of this situation and the ecological deterioration of these steppe rangelands, the need for an action plan to preserve and rehabilitate the degraded rangelands is becoming more and more urgent. Among the solutions […]
Economic valuation of rangelands is one of the best methods for conservation goals. A study was conducted to assess the economic value of forage loss under the two main forms of traditional pastoralism i.e. sedentary pastoralism and nomadism in historic grazing semiarid rangelands in Khabr National Park, Kerman province, Iran in 2019. Forage production was […]
