Bush encroachment is an increase in woody plant density typically resulting in impenetrable thickets, suppressing palatable grasses and herbs. Moreover, bush encroachment is a globally observed phenomenon. Besides, increasing the density of unpalatable shrubs and trees has reduced the carrying capacity and threatens the sustainability of grazing animal production, especially in arid and semi-arid grasslands […]
Mohammad Hossein Hakimi Meibody was born in 1963 in Meibod, Yazd province. He gets his diploma in Meibod and then for higher education, he went to Isfahan university and exceeded direction of plant science for 4 years and graduated in 1989 with excellent grade. Then, he went to Tehran university and passed course of Plant […]
Enclosure and Acacia shade availability to plants are basic variable in arid and semi-arid rangelands. the aim of this study was investigation the impact of patch enclosure and Acacia shade using four treatments which are Inside Enclosure Under Acacia shade (IEUA), Inside Enclosure Without Acacia shade (IEWA), Outside Enclosure Under Acacia shade (OEUA) and Outside […]
This study was carried out in Bale Eco-Region (BER) which is located in Southeastern Ethiopia with the objective of addressing the cause and effect of ecological damage, particularly rangeland degradation. Both purposive and stratified random sampling approaches were used to select HouseHolds (HH). Individual interview, key informants and Focus Group Discussion (FGD) were the main […]
The rangeland in the Khangai mountain region in Mongolia has degraded for the last decades mainly because of overgrazing and climate change. Livestock production is important part of the economy and is based on natural rangeland. In this research we seek to elucidate the influence of five years (2004-2009) of protection from grazing on vegetation […]
Soil microbial biomass plays an important role in nutrient transformation in terrestrial ecosystems. Microbial biomass is also an early indicator of changes in total soil organic carbon. Thus, the main objective of this study was to identify and quantify the present status of soil microbial biomass carbon and nitrogen with various management practices in Himalayan […]
Artemisia melanolepis Boiss. is an endemic, rare and endangered species inhabiting high altitudes at Sabalan Mt., Iran. This study aimed to identify the effect of environmental variables on the distribution of A. melanolepis, in southeast faced slopes of Sabalan Mt., Iran, in 2016. In the habitats of A. melanolepis two sites (A and B) were […]
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 […]
Rangelands represent a potential resource with a high socio-economic value. This value remains unmonetarized and therefore, not taken into account in public policies, which does not reflect the real value of this Ecosystem Services (ES) and negatively affects the sustainable management of rangelands. This study was carried out in 2019; it aims to estimate the […]
Fire occurrence may lead to a significant impact in many terrestrial ecosystems. This basin scale study attempted to evaluate the effects of fire on the water balance components in the Central Zagros, Iran in 2019. Two modeling frameworks including WetSpass-M spatial model and Bayesian Belief Networks were used to investigate the effect of fire on […]
