The variation of vegetation factors along the grazing gradient in Steppic Rangelands of Nodushan, Yazd Province, Iran

Elham Fakhimi abarghoie; Mansur Mesdaghi; ghasem ali Dianati tilaki

Volume 18, Issue 2 , September 2011, Pages 219-230

Abstract
  The large scale degradation of rangelands in Iran can be largely attributed to overgrazing. So investigation on the effects of grazing on vegetation parameters is vital to control the rangeland ecosystems degradation. The object of this study is to investigate the effect of heavy, moderate, and ...  Read More
