Artemisia is the major component of the vegetation of a large portion of arid lands in Iran. Determining the utilization rate is an essential element in the management of these rangelands. Methods of determining the utilization regime for woody plants and shrubs include clipping and weighing, reference unit, ocular estimate, twig length, branch diameter and production index. These methods were ...
