At the beginning of twenty-first century, the water crisis in the priority policy and management is inside and outside of the country as principle thoroughly human, social, economic and political rulers of the country is considered abundant. The World Bank has announced that during 1960 and 2025, water resources in Middle East, from 3430 m3 […]
Vegetation cover is the first barrier for the raindrops resulting to the interception and infiltration loss. Interception as one of the main components of ecohydrology equation plays a major role in the water balance of rangelands. However, few studies have been done on the interception of rangeland plants in Iran. This study was carried out […]
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), […]
This study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. The study was carried out in steppe rangelands of Saveh, Markazi province, Iran. Four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. To study […]
One of the ordinary methods to protect, rehabilitate, and enhance an ecosystem function in arid and semi-arid areas of the world is sand dune stabilization using biological practices. Plantation of species on the soil plays a great role in sustainable management of the ecosystem. This research studies the effects of cultivation of Haloxylon ammodendron and […]
The purpose of this study was identifying rangeland development and restoration operations targets. This study was conducted in Hossein Abad Bazoft basin with 7162 ha area, located in south east of Farsan County, Chaharmahal and Bakhtiari Province, Iran. The basin has various land uses including rangeland, forest, irrigated farm and garden, dry farm, residential area […]
This research was conducted to investigate the relationships between soil (organic matter, potassium, phosphorous, sodium, fine gravel, soil texture, EC, lime, gypsum, nitrogen) and environmental (elevation, slope) factors with distribution of vegetation types in rangelands of Sabzdasht, located in Bafgh, Yazd province at 2012. For this purpose, four vegetation types were selected as follows: Artemisia […]
Environmental pollution with heavy metals is a global disaster that is related to human activities. This study was conducted to determine the extent of heavy metals accumulation by plant species in Lia industrial city (Qazvin, Iran) and to investigate the remediative capacity of native plant species grown in the contaminated soils. Soil and industrial wastewater […]
Understanding the plant species diversity could be used as an important indicator applied for the natural areas management. The aim of this study was to investigate the relationships between soil characterizes with distribution and diversity of plant in vegetation types in Karvan district (located in west of Isfahan province). For this purpose, three vegetation types […]
Growth and productivity of plants are mainly affected by various environmental factors in different ecosystems and natural habitat in the world. This research aims to study the existing relationships between the phytosociology characteristics of Thymus kotschyanus and environmental factors in order to find the most important factors governing development of the species in middle Taleghan […]
