ABSTRACT

 

Rangelands in Iran are still commonly exploited by traditional utilization system in particular live stock production. Stakeholders in this system find surplus livestock as main factor changing vegetation composition as well as rangeland degradation, in turn results in livestock production losses. According to the importance of allowable livestock in Iran and impact on the improvement or degradation of rangelands, the aim of present research is to management the factors affecting range condition and forage production in Damavand Summer Rangeland (Northern Iran). To this end, number of seventy one stakeholders with public and council exploitation system was chosen as per Kokaran formula within eleven ranches. To determine range condition and forage production, four-factor clip and weigh methods were undertaken in given ranches or vegetation types respectively. Spearman correlation test showed that stocking rate within each ranch related negatively to range condition and production. Also, according to the results, allowed number of livestock determined by experts significantly from those real numbers in rangelands at probability level of 99% (t=17.29).
