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...

Some chemical characteristics of root, shoot and litter of index species such as Salsola rigida, Artemisia sieberi and Stipa barbata commonly used in rangeland development projects were evaluated and compared. Chemical properties of soil under and between the above mentioned species were also studied. For this purpose, vegetation types of Stipa barbata and Artemisia sieberi - Salsola rigida wer...

to assess the effects of livestock grazing on soil compaction (density changes), the trampling action of livestock was simulated. the research field was located to the south west of nazarabad in savojbolagh district, south west of tehran province. samples were annually collected based on a completely randomized design. from the triple regions (reference, key and critical) 36 cylindrical cores w...

in order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. physical and chemical properties of soil are effective in distribution of plant species in local area. to determine the effects of some soil properties on species distribution of eurotia ceratoides and stipa barbata in baghedar summer region of bafgh, three ...

abstract. the purpose of this study was to investigate the effects of topographical factors on the classification of grassland plant communities in the rangelands of ghorkhud, northern khorasan province, iran. for sampling, land units were specified. a floristic list was prepared using minimal area method based on the nested plot (braun-blanquet method). 116 10m2 furrows were selected. within e...
