Plant life and food production for human closely depend on fertile and healthy soil. Knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. In addition, Rangelands cover a very large portion of the earth’s surface and play an important role in food security […]
One of the effective ways for reducing atmospheric CO2 is carbon sequestration by plants and soils. Rangelands with an expanded area have a great potential for Carbon (C) Stocks. In this study, C stocks in three treatments including natural rangelands (NR), Pit- seeding by Agropyrum elongatum (PS) and abandoned dry farming (ADF) were examined in […]
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 […]
Negative impacts of gully erosion in marly areas are severe due to improper landuse practices such as irrigation, tillage, overgrazing and degradation of vegetation cover. The objective of this research was to evaluate gully thresholds related to plant vegetation cover and landuse change in the Agriculture (AG), Fair Rangeland (FR) and Weak Rangeland (WR) areas […]
There are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. The purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands […]
As far as Iran is concerned in arid and semi-arid region and amount of water is limited, improvement of water consuming is very important. One of the ways for storing water is to use superabsorbent polymer. So, this research compared normal and deficit irrigation methods by considering the effects of stockosorb (0.1% and 0.3% by […]
This study was performed to evaluate the forage nutritive value of Cymbopogon olivieri before and after conducting the essential oil extraction in rangelands of Khuzestan province, Iran. In this study, the aerial parts of Cymbopogon olivieri were collected in flowering stage from 10 natural regions located in Khuzestan province in 2016. Regions included ChalGandali, TalkhabKalat, […]
Semi-arid mountainous areas are of special importance in terms of ecological function i.e. vegetation dynamics and its evaluation under environmental- managerial factors is a necessity for their sustainable use. Due to the highly variable environmental characteristics in these areas, proper land management and utilization can severely affect the Range Condition (RC). Here, the relationship between […]
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 […]
