Rangeland Condition and the Appropriate Rangeland Management Methods

Improvement, development and proper exploitation of currentrangelands conditions and selecting a range management method(balanced, natural and, artificial) to be implemented in the form of arange management plan (RMP). Data was collected from therangelands of Haraz River watershed. Information including the totalpercentage of vegetation and each of the increasing species,rangeland condition and production were studied in 2016. Todetermine the best range management method, the analysis ofvariance was used. To compare the quantitative characteristicsmeasured before and after the implementation, a two-sampleindependent t-test was used. Mann-Whitney U test was used tocompare qualitative characteristics. Results showed that thevegetation percentage of palatable species composition did notincrease, the balanced and natural methods were the best methods ingood and fair rangeland condition. The reason for the lack of increasein the number of palatable species was the unsuccessfulimplementation of planned programs in RMPs. The artificial methodwas performed in the RMPs with poor vegetation types, theimplementation of these plans had no significant effect on therangeland condition of the study rangelands due to the high livestockpopulation. Rangeland plans will be more effective when there is abalance between grazing capacity and livestock population.
