Considering the poor condition of most rangelands of Iran, evaluation of rangeland potential and determination of suitability for continuous and optimal utilization seems necessary. The purpose of this study was to investigate the rangeland suitability for sheep and goat grazing using FAO and GIS methods. Therefore, three criteria including vegetation cover, water, and soil were studied. The ...

One of the key factors in managing a rangeland is to determine the relative preference of its major plant species by thegrazing livestock. Preference value of each plant species is affected by plant type, companion plants, availability byanimals, phenological stage, climate condition, and the livestock species. We investigated the grazing behaviour of anative goat (Garizi) in the steppe rangela...

Wissman, J. 2006. Grazing regimes and plant reproduction in semi–natural grasslands. The dominating grazing regime in semi-natural grasslands today is continuous grazing throughout the season, and a high grazing pressure is often advised in order to avoid litter accumulation. Traditional management, on the other hand, included late mowing and grazing, which favoured plant flowering and seed pro...

Routes of transhumance movement as well as both summer and winter destinations are subjected to intense grazing that over the years may shape landscapes. The aim of this study was to investigate land use changes in Aspropotamos area, Trikala from 1985 to 2000 that serves as a summer destination of transhumance flocks. Changes in land cover were explored with the post classification comparison a...

Land degradation is one of the most significant environmental problems in the semi-arid and arid savannas of Southern Africa. Degradation affects vegetation structure, cover and patchiness and this result in the loss of vegetation resources used by rural populations (grazing, fuel wood, and other non-timber forest products) and wildlife. Land degradation processes are influenced by rainfall, la...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...

This study was conducted at Eldebeibat area, in South Kordofan State, Sudan. The aim of this study was to assess the role of competition on rangelands’ utilization on occurrence of conflicts between land’s users in the semi-arid areas of Eldebeibat, Sudan. Two target questionnaires were designed to collect data from two groups of land users namely nomadic pastoralists and sedentary farmers that...
