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 […]
Information on different rangeland plants’ nutritive values during various phonological stages is of importance for the rangelands management. This information helps rangeland managers to choose proper grazing times to achieve higher animal performance with no detrimental effects on the rangeland vegetations. Effects of various plant parts’ phenological stages and vegetation types on reserve carbohydrates and […]
The effects of Range Management Plans (RMP) on soil and vegetation characteristics were studied in Eshtehard rangelands at Alborz province. The parameters of yield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%), Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sites of Ghenzel Cheshmeh as RMP and […]
Groundwater is among the most important resources of drinking water supply of the worldwide population. Use of recharge area is one of the methods for artificially recharging groundwater. Selection of suitable sites for artificial recharge is very important and must be carried out accurately. There are different types of land use, only rangelands are appropriate […]
There are some barriers for rangers to take part in range plan projects and evaluation. Their participation is very useful for range managers to plan and provide solutions for solving problems. This study aims at comparing barriers of participating from rangers and experts point of view in Lar moor rangelands, Tehran, Iran. In this research, […]
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. […]
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 […]
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 […]
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 […]
