Rangelands are important for plant productivity, livestock production, wildlife, conservation of soil and water resources, and etc. One of the main problem of rangeland is that has not been used based on its potential that leads to more degradation of rangelands. The purpose of this study was to evaluate the range management capability of Badreh […]
One of the influential tools concerning the rangeland and vegetation sciences is the technology of remote sensing and satellite data. Satellite data have played essential roles in preparing the needed information for studying the vegetation. Vegetation has been widely recognized as one of the best indicators for determining the land conditions. Using vegetation indices is […]
Subalpine rangeland as a rara avis ecosystem is very important because of ecological features. Consistency and resistance of this ecosystem is so frangible and its natural equilibrium is instable due to the effects of biotic and abiotic factors. The landslide as one of negative consequences in upland area is seen in Masoleh watershed (north of […]
The major aim of processing satellite images is to prepare topical and effective maps. The selection of appropriate classification methods plays an important role. Among various methods existing for image classification, artificial neural network method is of high accuracy. In present study, TM images of 1987, and ETM+ images of 2000 and 2006 were analyzed […]
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 […]
Grass pea (Lathyrus sativus L.) has a high potential for forage production in both rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas of west and north of country where annual rainfall is 250–350 mm. To study the seed and Dry Matter (DM) yield and agronomic traits, six genotypes of […]
Soil erosion is a serious problem especially in northern parts of Iran. One the most important side effects on soil erosion may be the decline in qualities of soil refers to agricultural productivity. So it is very important to assess the soil erosion risk for the sustainable development of agriculture. This study outlines ways undertaken […]
