Application of remote sensing information to estimate production and plant cover percentage(Study area: Rangelands around Choghakhor Wetland in Chaharmahal and Bakhtiari Province)

Jamal Imani; Ataollah Ebrahimi; Bahram Gholinejad; Pejman Tahmasebi

Volume 28, Issue 3 , October 2021, , Pages 450-471

Abstract
  The present study was conducted to investigate the differences between several remote sensing indices, four different plot sizes and two different sampling methods to estimate the percentage of plant cover and production in three plant communities in 2013. Ground sampling was performed in three communities ...  Read More

Effect of integrated fire period and intensity grazing on plant species diversity in the semi-steppe rangeland of chaharmahal and bakhtiari province

Ali Mohammadian; Esmaiel Asadi borujeni; Ataollah Ebrahimi; Pezhman Tahmasebi; Ali Asghar Naghipour

Volume 27, Issue 1 , April 2020, , Pages 84-97

Abstract
  This study was was don to investigate the interaction  of fire and grazing effects on index of vegetation diversity in Semi-steppe rangelands in Chaharmahal - Bakhtiari Province.Therefore, 16 sites was selected with different periods of fire and grazing intensity and 18 quadrates along transects ...  Read More

Effects of different grazing management on plant functional traits in a semi-stepp rangeland, Karsanak, Chaharmahal-Va-Bakhtiari Province

Elham Banihashemi; Pezhman Tahmasebi; Esmael Asadi

Volume 25, Issue 3 , November 2018, , Pages 547-561

Abstract
      Livestock grazing is one of the most important factors influencing on the structure and dynamics of the rangeland vegetation. The aim of this study was to identify the plant functional traits as the indicators for the effects of grazing management on Karsanak semi-steppe rangelands ...  Read More

Comparison of NDVI and SAVI in three plant communities with different sampling intensity (Case Study: Choghakhour Lake Rangelands in Charmahal & Bakhtiri)

Jamal Imani; Ataollah Ebrahimi; Bahram Gholonejad; Pezhman Tahmasebi

Volume 25, Issue 1 , April 2018, , Pages 152-169

Abstract
      Identifying and evaluating rangeland ecosystems is the first step in managing these resources. Without knowledge of rangeland condition, no management plan can be developed for it. For this purpose, three sites with different dominant species were selected for sampling. In each site, ...  Read More

Comparison ground samples establishing, number and areas in Landsat 8, 30×30 pixels to aware correlation plant cover percentage with NDVI index in three study areas (Study area: Rangelands around Choghakhor Dam Lake in Chaharmahal & Bakhtiari province)

Jamal Imani; Ataollah Ebrahimi; Pejman tahmasebi; Bahram Gholinejad

Volume 24, Issue 2 , July 2017, , Pages 429-440

Abstract
  The use of satellite data is one of the proper methods, which makes studying ecosystems less costly. This research was carried out to determine the correlation among the vegetation cover of dominant species in three sites with the NDVI index. For this purpose, a study was conducted on three different ...  Read More

Comparison of Species Richness and FAD2 Functional Diversity in Order to Estimate the Biomass Production in the Central Zagros

ali goharnejad; pejman tahmasebi; esmael asadi; javad motamedi

Volume 24, Issue 1 , May 2017, , Pages 1-15

Abstract
  In contrast to the taxonomic biodiversity, based only on the relative abundance of species in the community, functional diversity summarizes various aspects of the biological composition and, hence, the role of populations in the community. Functional diversity may be linked directly to the ecosystem ...  Read More

The effect of fire and grazing on density, diversity and richness of soil seed bank in Semi-Steppe rangelands of Central Zagros region, Iran

Ali Asghar Naghipour borj; Jamaladdin Khaeddin; Hosein Bashari; Majid iravani; Pejman Tahmasebi

Volume 23, Issue 3 , January 2017, , Pages 442-453

Abstract
  The structure and composition of plant communities are mainly affected by fire and grazing, especially in arid and semiarid rangelands. This study aimed to investigate the role of fire and grazing on soil seed bank characteristics (density, diversity and species richness) in semi-steppe rangelands of ...  Read More
