Recognizing the herbaceous plant species diversity could use as an important indicator applied for the rangeland and forests management. Considering the presence of vegetation and animal husbandry in Zagros region, Iran, being aware of the diversity and richness of plant species is necessary to management or the destructed vegetation restoration. In order to study the […]
Species diversity, richness and biomasses (aboveground biomass) and their relationships are the key variables of ecosystems. This study was conducted to determine the relationship of Species Diversity (SD) and Species Richness (SR) with Above-Ground Biomass (AGB) at a local scale at 5 different habitats (shrubland, forbland, grassland, shrub-forbland and forb-shrubland) in Zagros mountains in west […]
TThe Leguminosae family plays a significant role in rangeland ecosystems with biological nitrogen fixation for soil fertility. The grasses significantly increase rangeland production and sustainability. Legume-Grass Ratio (LGR) is an indicator of soil fertility. This study was aimed to investigate the LGR and some soil properties in four vegetation types (Stipa arabica Trin.-Medicago sativa L., […]
The use of modern methods in the analysis of rangeland ecosystems has received much consideration. The study of the diversity of medicinal and sometimes toxic species in rangelands can be regarded as an indicator of ecological status changes in rangeland ecosystems. In the present study, Javaherdeh mountain rangelands in north of Iran were selected under […]
Economic, social, and ecological factors in rangelands affect range management. By integrating and studying these factors, a more appropriate method can be applied to assess the sustainability of rangelands. In the present study, Analytical Hierarchy Process (AHP) as well as the experiences and views of rangeland exploiters and nomadic and natural resources experts in Kerman […]
This research was conducted in Mustang district to see the effect of plant diversity and soil properties on aboveground biomass in altitudinal gradient. Above ground biomass estimation was done using various mathematical equations. Soil properties determination was done using calorimetric, Kjeldahl Dry-block method, feel method and core sampling methods. Simpson’s Diversity Index and Shannon-Wiener’s diversity […]
