Some of arid regions problems of Iran are saline and sodic soils. In improvement and reclamation of Iranian arid rangelands, some foreign species of Atriplex had been imported and adapted for many years ago. The most adapted species was Atriplex canescens. At the present research, some environmental factors, vegetative characteristics (Na, Ca, Mg and K), […]
Livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. This research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of Artemisia aucheri. Hence, two rangelands of enclosure (Shahtappeh-Chah Mahmood) and […]
Today, in the rangeland management science and determination of range capacity, accurate and true information about range production is crucial. In fact, range production is considered as a basis for range management. The aim of this study was to compare different methods for the estimation of forage production with four sampling methods in the rangelands […]
Classifying remote sensing imageries to obtain reliable and accurate Land Use/Cover (LUC) information still remains a challenge that depends on many factors such as complexity of landscape especially in arid region. The aim of this paper is to extract reliable LUC information from Land sat imageries of the Pishkouh watershed of central arid region, Iran. […]
Awareness of the effects of fire on various aspects of an ecosystem after the fire, is important for range management. Changes in soil physical and chemical properties caused by fire can be the cause of changes in the vegetation. In this study, effects of fire on physical and chemical characteristics of soil were investigated. This […]
Soil salinity is one of the important factors which can influence the growth and distribution of plant species. Saline and alkaline rangelands of Golestan Province, Iran with low-deep underground water level are considered as a halophyte plant species growing area. Attempts have been made to determine soil salinity and its relationship with Frankenia hirsuta L. […]
We have studied the medicinal plants of Ghasemloo and then surveyed the usage percentage of different parts from each specimen for the medicinal or diet consumptions at three sites from the adjacent villages of Ghasemloo valley, villages of West and East Azerbaijan including 17 questioners.

The aim of this research was to investigate the effect of index species, Astragalus ammodendron on the associated plants of Agropyron tauri and Bromus tomentellus from different aspects in Shazand rangeland in southwest of Markazi province. The effects of species density and distribution pattern and then index species on the soil properties were studied. Based […]
In the present study, the Tangrah region located in the vicinity of Golestan National Park was selected for exploring the changes in the amount of the secondary essential of hypericin in Hypericum perforatum in different highlands of the eastern Golestan province. The aerial flowered parts of the herb were collected randomly and in three replications […]
