Investigating the effects of range management plans on condition, production and rangeland’s trend of rudan and hajiaba cities, Hormozgan province, Iran

Rangeland management projects considered to be a management tools to increase the quantity and quality of the rangelands. Persomably, It could work more efficintley in areas where the grazing pressure is high and consequently their condition and trend are regressive. In this study, production, range condition and range trend were examined before and after the implementation of the range management projects in 2018. For this purpose, 10 more or fewer uniform rangelands were selected. To collect the data 30 plots 1*1 size were established. In each vegetation type, production factors, condition and trend at the time of rangeland preparation (mid-October to mid-April of each year) were measured and evaluated. Statistical analysis of data was performed by t-test using SPSS software. Results showed that the rangeland condition in all sites with ling lasting the rangeland plan coverage, more than 12 years, were selected. Results showed that implementation of the plan has improved the situation. With the exception of the Hajiabad kafeh shour kahgum which has not been changing. The difference between the average production and the condition before and after the implementation of the rangeland plans at the error level of 1% was significant. The results of t-test in 5 sites of Rudan city before and after the implementation of the rangeland management plan showed significant differences at the level of 99%. For low quality pastures howeve the level was 95%. The average total forage production the implementation of the range management project, production has increased from 54.7 to 63 kg per hectare per year. In the two low-range rangelands of Kamrome and the Tomb Mirh Bahar, the average production increased from 63 to 124 kg and 40 to 78 kg, respectively. This study indicated that implementing range management plans can enhance forage production, range condition and trend therfore it can conserve rangeland sustainability in the long term.
