Floristic studies are fundamental for the applied sciences such as rangeland management and conservation. Unique ecological and climatic conditions in the Northern Khorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant species were collected from 50 field sites, representing major habitats of winter and rural rangelands. Surveys were conducted during active […]
This study was conducted to compare the methods of seed bed preparation in rangelands of Khash region in Sistan and Baluchestan province in Iran. A split plot design was conducted based on Randomized complete block design with three replications in 1999. Five seed bed preparation methods were used as main plot as: 1) Seed sown […]
In order to study the effects of three operations of rangelands on the properties of vegetation in rangelands, this research was conducted in Chaat Gonbad, Golestan province, Iran in 2004. Chaat area is located in 50 km of border road of Dashlibroun to Maravetappeh in North of Attract River (border of Iran and Turkmenistan). The […]
Ecotones are zones of gradual changes from an ecological system to another. Ecotones monitoring could be important to find out the reason for changes and limits. In this research satellite data were used to analyze the ecotone boundary in Fars steppic rangelands using IRS LISS III and Pan data of year 2006. The real vegetation […]
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 […]
Harvester ants are known as one of the most renowned bio-disturbances in the arid and semi-arid ecosystems that affecte vegetation by collecting seeds and harvesting plants. It seems that physiognomy of plant association in steppe shrub land of Roodshoor, Saveh, Iran has been highly changed by harvester ants’ activities that caused to conduct this research. […]
Natural resources have been attracted a great deal of attentions and have been frequently exploited for many years. Dust is one of natural disasters mainly in recent years; here, in south west of Iran, it had destroyed the rangelands. The dust has detrimental effects on the rangelands, livestock and livestock production. High concentrations of dust […]
Maharloo Lake is one of the salty lakes located in the southeast of Fars province, Iran. Presence of salt domes has a significant role in its salinity. Magnesium-sodium chloride and sodium sulfate are dominant salts of the lake. Due to the drying up of lake, widespread lands surrounding the area are exposed to secondary salinity. […]
Natural resources play a fundamental role in the economy of country and create the situation to achieve the goals of sustainable society, these valuable resources have to be conserved and used with care. Destroying the forests and rangelands will lead to a dark future full of poverty, starvation and environmental pollution. Forests and rangelands play […]
Adverse changes in rangeland vegetation can be considered as one of the criteria for land degradation. Some of these changes can be evaluated through monitoring the spatial changes of landscape parameters. This study aimed to investigate the landscape changes in Kezab rangelands of Yazd province, central Iran. Landsat satellite images of 1990, 2002, and 2013, and […]
