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 main objective of an ecosystem sustainable management is to preserve its capacity to respond and adapt to current disturbances and/or future changes, and maintain the provision of environmental goods and services. Two very important properties linked to this objective are the ecosystem resilience and resistance to disturbance factors. The objective of this paper is […]
Erosion is one of the important social-economic problems in Iranian catchments that have been posed by surface water vastness and runoff production. So, the study of water resources, soil erosion and effective factors is of high importance. Gully erosion also extends in many parts of Iran and its study particularly in viewpoint of sediment yield […]
This research was conducted to investigate the factors contributing to the failure in the forestry and rangeland by-product cooperative companies in Lorestan province, Iran. A descriptive-correlative research design was used. The statistical populations were 1100 people divided into two groups of experts from natural resource agency in Lorestan province and members of cooperative companies. The […]
Five common range forage including Agropyron intermedium, Bromus tomentellus, Hordeum bulbosum, Cousinia bakhtiarica and Scariolla orientalis, were sampled during three phenological stages, from controlled rangeland stations over five locations in Chaharmahal and Bakhtiari province, Iran. All samples were chemically analyzed for Crude Protein (CP%), in vitro Dry Matter Digestibility (DMD), Organic Mater Digestibility (OMD), Ether […]
This research was conducted to identify the limitative factors of forage production suitability in order to achieve the sustainable exploitation of natural ecosystems in Aliabad Watershed in Lorestan in 2013. The field measurements have been done through cutting and weighing method to estimate the forage amount, four-factor method to determine the range condition, trend scale […]
Using satellite imagery for the study of Earth’s resources is attended by many researchers. In fact, the various phenomena have different spectral response in electromagnetic radiation. One major application of satellite data is the classification of land cover. In recent years, a number of classification algorithms have been developed for classification of remote sensing data. […]
Plant biomass is an important factor for determining arid and semi-arid rangelands capacity. Due to the lack of proper and annual sampling of rangelands, there are no suitable data to determine biomass, range condition and proper range management operations. Plant biomass is one of the measurable attributes that can be assessed in rangeland studies. Since […]
In recent years, studying the dietary preferences and livestock grazing behavior has attracted lots of attention due to manage and improve the efficiency of rangelands. So, in this study the foraging behavior and diet selection of Tali goat was investigated in the Chabahar Rangeland during 2008-2010. Data were collected and analyzed for speeds of livestock, […]
In order to study of ecological and phenological traits of Ferulago angulata as an important medicinal plant, this research was conducted in Hezar Mountains and Bondareh Henza in Kerman province, Iran. Random samples of this plant were taken and their vegetation habitat conditions and their growth characteristics including height of collar leaves, height of flower […]
