Observing livestock grazing time in rangelands is quite important for conservation of rangelands and protecting them against degradation. This study was aimed at assessessment of factors that contribute to observing grazing time in rangelands of Kouhdasht County in Lorestan province. This study is a survey research and the statistical population is composed of nomadism pastoralists of Koohdash County. Based on Cochran formula, sample size was defined 310 persons out of 1038 pastoralists. Many different variables including socio-economic conditions of users and factors contributing to grazing management were assessed in this study. Among the econometric models, Logit Model was used in order to assess factors impacting on time management of grazing. Logit model parameters were estimated with maximum likelihood method. Coefficient of determination and accurate prediction percentage were used in order to assess the finesses of sample’s data. Results showed that there is a significant differencebetween different groups of users in terms of considering grazing time. Having winter pastures, early arrival date, and late exit of pastoralism from summer rangelands had the highest effect. Based on achieved results, when heads of families were pastoralists, households were much more dependent on rangelands as a source of livelihood. Therefore, they entered earlier to summer rangelands. Besides, those who did not have winter pastures were less inclined to care about grazing time. In this regard, if they are further supported through handy feeding, they will be motivated to observe grazing time. Kuhdasht is an active center in livestock farming. Entrance into and exit of livestock out of the rangeland leaves direct and indirect impacts upon local life. It has as well negative effects on rangeland vegetation. Defining factors that affect on livestock entrance and exit will help planners to take appropriate measures for removing problems.
