Investigation of forage production, range condition trend and range condition in audition and management plant ranges (A case study in Noudushan's ranges, Yazd)

Nowadays، the rangelands were devastated as result of population and domestic growth and hence unsparing use of food. Thus correct management as restoration، plantation of seedling، fair and rain harvesting techniques is a method that human can use for rangelands improvement. In this research were selected two treatments as have done management plan range and an audition range then were selected three same parts as repetition for every treatment. Then in every replication had been amount of forage production by cutting-weight method and vegetation cover by plot (1×1) m2 and range condition by four factory and range condition trend by balance method. After data collection were analyzed by using T-test. results showed there is significant between forage production and range condition in management plan and audition ranges (P<0. 01). Also range condition trend is not significant between both of them (P>0. 05) and there is significant vegetation cover between both of them (P<0. 05).
