Volume 70, Issue 3 , December 2017, , Pages 723-734

https://doi.org/10.22059/jrwm.2017.113281.803

Abstract
  Intensive livestock grazing is one of the most important destructive factors in rangelands that leads to decrease of diversity and causes disappearance of sensitive plants. On the other hand, considering the scales in assessment of diversity is very importance to study the variability of plant diversity ...  Read More
