The widely area of each state consist of rangeland with special vegetation and livestock in which are compatible to existing conditions. Livestock has special grazing and feeding behavior in pasture. Due to the large scale of rangelands area and high costs of improvement projects, this is essential to identifying the animal requirements and preference value of plant species for them before any practices. Winter and summer pastures in GarmSar city are mainly used to feeding livestock such as camel, sheep and goat. This research was conducted by using timing method to evaluate the preference value of the plant species for camel in summer and winter pastures for three consecutive years (86 -88). The results showed that camel feeds on thorny forb and thorny shrub such as Alhagi psedoalhagi, Halocnenum strobilaceum and Tamarix leptopetata in summer and winter rangelands. Other life form plant was consumed less than thorny plants and grasses such as psathyrostachys fragilis and does not used generally.
