Range management needs information on distribution of livestock. The better the distribution of the livestock, the more uniform the use of the rangeland. This study was conducted to record the path of the herd steering by the shepherd. A GPS was attached to a three year old ewe which was moving with the flock. The […]
The efficiency of three statistical models, AHP surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in Chehel-Chai watershed in Golestan province, Iran. In current study the hazard map was prepared according to the top model of landslide hazard map. Chehel-Chai watershed is located as one of Gorganrud river […]
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 […]
The diversity and richness of species are of important components to evaluate the health of ecologic system of rangelands. This research was conducted to investigate the biodiversity in riparian and neighboring areas via comparison of indices in Javaherdeh rangeland of Ramsar. Plot-transects was randomly used to estimate diversity, richness, dominance, and evenness indices in two […]
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 […]
Medicinal species of mountain’s kelavs, scientifically named (kelussia odoratissmia Mozaffar.) is an endemic species in Iran. Kelussia odoratissima is a perennial species and belongs to the umbelliferae. From the ancient times, the local and nomad societies had believed that the species traditionally have anti-ache, anti-inflation and anti-cough effects. Seed and root of this species are […]
The genus Thymus is perennial medicinal plants belong to the Lamiaceae family that is used for different propose in pharmaceutical industry. Environmental stresses, particularly salinity, are considered as the major factor reducing plant growth. The purpose of this study was to investigate the effects of salt stress on germination characteristics and seedling morphology in two […]
Renewable natural resources are the wealth that not only belongs to the current generation but also to future generations. Diversity in rangeland user viewpoints and policy makers has caused these lands to face some damages. This study was conducted to compare viewpoints of ordinary members as rangeland users, and board of directors as executives of […]
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 […]
In order to estimate the nutrient value of three dominant range species; Festuca ovina, Trifolium montanum and Alopecurus textilis via proximate analyses and gas production technique, samples were collected in three stages during grazing period from 26th May to 1th September in six areas of Sabalan Mountain in North West of Iran. Results showed that […]
