Kelussia odoratissima is a perennial species and belongs to the umbelliferae. From the ancient times, the local and nomad societies had believed that the species traditionally have anti-ache, anti-inflation and anti-cough effects. Seed and root of this species are […]
Infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. The most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to […]
Plant biomass is an important factor for determining arid and semi-arid rangelands capacity. Due to the lack of proper and annual sampling of rangelands, there are no suitable data to determine biomass, range condition and proper range management operations. Plant biomass is one of the measurable attributes that can be assessed in rangeland studies. Since […]
Rangelands are one of the most vulnerable parts concerning the climate changes‟ impacts. These impacts are even stronger in the arid and semi-arid areas where rangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out the actual dynamics of climate variations on the rangelands. The aim of this research was to determine […]
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We […]
Rangelands are known as one of the main income resources for their exploiters. In the recent century, management of Iran rangeland has undergone vast transformations because of vulnerable socio-economic conditions of pastoralists. A study was done to provide a clear picture of the status and utilization of Aq Qala rangelands via assessing internal and external […]
Natural resources have been attracted a great deal of attentions and have been frequently exploited for many years. Dust is one of natural disasters mainly in recent years; here, in south west of Iran, it had destroyed the rangelands. The dust has detrimental effects on the rangelands, livestock and livestock production. High concentrations of dust […]
FAO and World Bank promote livestock rearing as a way of poverty alleviation and food security especially among rural poor. Villagers are usually involved in mixed crop-livestock farming. Interviews with villagers in the HableRud basin revealed that some changes have happened and comparing with past decades, fewer villagers keep livestock. They believed that number of […]
The aim of this study was to investigate the members’ opinions regarding the influencing factors contributing the success of range management cooperatives in three provinces as Markazi, Tehran and Isfahan of Iran in 2014. The study populations were board and ordinary members of cooperatives (N=750) and the samples were selected using Krejcie and Morgan method […]
There is less published research on ecosystems of forested rangeland in Iran. This research was conducted to investigate the forested rangeland area based on legal definition via comparison of indices species richness, diversity, and morphology of the trees and shrubs in Sabzkouh watershed, Chaharmahal Bakhtiari province, Iran. Quantitative characteristics of trees and shrubs were measured […]
