Annually, 200 ha of Agh Ghala rangelands in Golestan, Iran are under Alkaligrass Puccinella distans”s cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. The current study aims to reduce such costs through the examination of apt sites to grow P. distans in northern […]
Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian […]
Information on quality characteristics of forage species help the range managers to select a suitable grazing program that minimizes the damages to vegetation. Water Soluble Carbohydrates (WSC) -the main photosynthetic products- are stored in various plant parts and are more likely to be consumed when plants require them. In order to investigate the changes of […]
Salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide Approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. This study was conducted to determine the ion exchanges in Halocnemum strobilaceum and Halostachys […]
Climate changes and global warming are considered as very important challenges of sustainable development. Carbon sequestration is the easiest and cheapest way to reduce the greenhouse gases, especially carbon which constitutes the largest portion of them. In the present study, the potential of carbon sequestration in four plant species of Atriplex canescens, Haloxylon persicum, Artemisia […]
In recent years, rangelands have been regarded as potential carbon sinks. One of the most widely suggested options to sequester more C in rangelands is the restoration of the degraded rangelands through grazing the exclusion. In present study, the effects of exclusion on the carbon sequestration of Gomishan rangelands were investigated. Three transects were established […]
One of the main objectives of ecosystem management is to preserve the species diversity. Many researchers regard higher species diversity as the stability of ecological systems. The aim of this study is to investigate the stability and relationships between topographical factors with diversity indices in Ghorkhud mountainous rangeland in northern Khorasan province, Iran. For data […]
The overgrazing and excessive utilization of rangelands has caused vegetation and soil degradation in many rangelands. In the rangeland management, the soil and vegetation elements, environmental factors and livestock should be considered as decision making agents. Various methods are applicable for the rangeland restoration as contour furrows and mortar stone dam. In order to evaluate […]
Tragacanth Gum is one of the most important medicinal and industrial products of rangelands and is obtained from the incision of gum tragacanth-producing Astragalus including Astragalus keyserlingii. The conservation of Astragalus species in rangelands has a special place in terms of economic profit and soil conservation. The increase in price of gum tragacanth in recent […]
Plant life and food production for human closely depend on fertile and healthy soil. Knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. In addition, Rangelands cover a very large portion of the earth’s surface and play an important role in food security […]
