rangelands are among the natural resources which have a considerable effect on environment and man’s life. iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. the main objective of this study is to evaluate ecological capability and land suitability of gheshlagh dam’s watershed a...
rangelands are the main sources of forage for livestock feeding by localpeople. beside forage production, rangeland ecosystems provide many other goods andservices such as medicinal plants, recreation, soil and water conservation, wildlife habitat,fishing, hunting, hiking, etc. nevertheless, there are no much information about the waythat local communities think about the rangelands goods and s...
desert and marginal lands of playas which are covered with halophyte shrubs, play a great role in supply of forage for livestock as winter rangelands. in this research, plant samples were collected from four palatable halophyte species for zandi sheep of qom desert rangelands including seidlitzia rosmarinus، halocnemum strobilaceum، alhagi camelorum and tamarix passerinoides in two phenological...
