Study on the effect of Livestock Grazing on Plant Species Diversity Components in Semi-arid regions

Reza midipour; Reza Erfanzadeh; Marzban Faramarzi

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


  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

Maryam Azarakhshi; Mohammad Mahdavi; Hasan Ahmadi; Hosein Arzani; Jalil Farzadmehr

Volume 68, Issue 4 , January 2016, , Pages 885-899


  Plants cover composition, condition, trend, production, and grazing capacity of the rangeland change annually. In this research, the role of temporal rainfall distribution on rangeland production was assessed. This research had down in the rangelands of Ilam (with semiarid to semi humid climate) and ...  Read More

Comparisons of different models for landslide susceptibility mapping in Zangvan watershed, Ilam province

Haji Karimi; Fathollah Naderi; Behrooz Naseri; Ali Salajeqeh

Volume 67, Issue 3 , December 2014, , Pages 459-485


  Distinguishing the susceptible areas to landslide using different landslide susceptibility mapping (LSM) models is one of the primitive and basic works to reduce probable damages and reduce risk. The main purpose of this research is the efficiency evaluation of four methods including Information value ...  Read More
