Volume 25, Issue 1 , April 2018, , Pages 54-62
Abstract
Awareness of annual and monthly production of various rangeland types is essential for efficient management of rangelands. It would be achievement by determining the relationship between plant forage production and climatic variables affecting them especially rainfall which would make easier management. ...

Volume 22, Issue 2 , August 2015, , Pages 205-215
Abstract
In order to study thechanges of seasonal production and consumption of range species during the growing period and grazing season, SarAliAbad rangelands were selected, representing a semi-steppe area. Production was measured inside an exclosure and consumption was estimated outside the exclosure under ... Read MoreVegetation changes in semi-steppe rangelands of Golestan province (Case study: Maraveh tapeh)
Volume 21, Issue 4 , March 2015, , Pages 685-697
Abstract
Studies on vegetation changes in rangelands, under grazing and exclosure conditions are important in planning range management programs. This research was aimed to investigate the changes in vegetation inside and outside three exclosures of Maraveh tapeh during 1997-2005. The canopy cover was measured ...

Volume 19, Issue 2 , September 2012, , Pages 321-332
Abstract
In range management, appropriate time for utilization is set based upon plant life stages. Accordingly, phenology of Stipa hohenackeriana was studied in three research sites of Roudshor, Hasaan Abad and Khojir. This study was performed during three growth stages in 3 years. Twenty ... Read MoreEffects of exclosure and grazing on vegetation changes in Arquin site of Zanjan
Volume 16, Issue 4 , January 2010, , Pages 493-504
Abstract
As the documents and reports reveal, the condition of rangelands of Iran is poor or very poor in most areas; therefore, the percentage of invader species is dominant. The study of vegetation changes under strict exclosure and grazing is critical to understand the extreme problems of rangelands of Iran. ...
