The rangelands, as one of the largest dynamic biomes in the world, have very capabilities. Regulation of greenhouse gases in the Earth's atmosphere, particularly carbon dioxide as the main these gases, is one of these cases. The attention to rangeland, as cheep and reachable resources to sequestrate the carbon dioxide, increases after the Industrial Revolution. Rangelands comprise the large par...

sustainable range management needs the accurate estimation yield and determining of grazing capacity in rangelands. it is easy to obtain yield estimation with indirect methods. for this purpose, the relation between cover and forage yield of range species were studied in steppic rangelands of yazd. measurements of cover and forage yield were carried out with plot area and clipping and weighting...

Abstract Grazing exclusion has been proved to be an effective approach for naturally restoring degraded rangelands. Still, the effect of this management practice on plant community composition and structure is ambiguous, especially under prolonged repeated drought events. Here, we investigated responses (i.e. incidence-based) abundance-based) short-term sheep grazing severe episode in arid step...

more than half of the area of the country are rangelands. implementing the principles of proper rangeland management and optimal use of rangeland requires proper stock grazing management. considering the quality and quantity of forage plants, palatability and preference value of species and rates of species utilization are information needed for proper management of livestock grazing in rangela...

the present research was done in steppic rangelands of dehno, kerman province to study theeffects of different harvesting intensities of artemisia sieberi applying simulation method. theexperiment was conducted using split plots in a completely randomized experimental designof ten replications to find the best grazing intensity. treatments are including no harvest (as acontrol), 25, 50 and 75% ...

a major part of the rangelands of iran are located in arid and semi-arid regions. in this climate, rainfall fluctuation is an important factor which affects vegetation and forage production. in dry years that rainfall decreases, surface vegetation and forage production is damaged. this study was conducted on semi-steppic rangelands of ardebil over nine years (1999-2007), to study of vegetation ...

Livestock grazing potentially has substantial influence on fuel characteristics in rangelands around the globe. However, information quantifying the impacts of grazing on rangeland fuel characteristics is limited, and the effects of grazing on fuels are important because fuel characteristics are one of the primary factors determining risk, severity, continuity, and size of wildfires. We investi...
