the present study aimed to investigate the success rate of three rangeland cooperatives in the villages of Barabad, Negin Baniyabad, and Mehrabad in Khaf County, the factors affecting their success, and the obstacles and limitations in 2019. In order to sample from the statistical population of cooperative members, a stratified random sampling method was used. The study was conducted using a questionnaire and the sample size was 98 people, including 80 cooperative members and 18 cooperative managers. The validity and reliability of the questionnaire were examined based on the opinions of experts and the average value of Cronbach's alpha coefficient. In order to investigate the factors affecting the success of rangeland cooperatives, Pearson correlation coefficients and chi-square values were used. Then, with the help of stepwise regression, the effective factors were extracted. Also, Student's t-test was used to compare the success of rangeland cooperatives from the perspective of ordinary members and rangeland cooperative managers. Friedman test was used to prioritize variables. Participants in the study reported the success rate of Khaf County rangeland cooperatives as good with an average of 4.26. Among the managerial competencies, the ability to establish appropriate and effective communication with rangers was selected as the most important competency of managers of rangeland cooperatives. Three educational and extension activities, including extension visits, contact with natural resource promoters, and educational and extension classes, have the greatest impact on the success of cooperatives. Among the socio-cultural factors, active and effective communication between rangeland cooperatives and the level of education of cooperative managers, both with a score of 4, are among the most important factors affecting the success of rangeland cooperatives. Among all the factors studied, management factors and carrying out side activities with respective scores of 4.13, 3.98, and3.95, had the greatest impact on the success of cooperatives. The results of prioritizing obstacles and limitations showed that the lack of effective government support and interference instead of support, weakness and financial problems are the main obstacles to the success of these companies (R2=60). It is recommended that an integrated program be implemented to empower the managers of the cooperatives.
