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...

Soil moisture is generally regarded as the limiting factors in rangeland production. Although many studies have been conducted to estimate soil moisture in semiarid areas, there is little information on mountainous rangelands in west of Iran. The present study aims to investigate the soil moisture estimation in rangelands as compared to the other land uses over a mountainous area in central Zag...

Agro-sylvo-pastoral systems are common around the Mediterranean Basin, where they provide a variety of goods and services to local populations. Their sustainability relies on efficient grazing management, especially in rangelands. The diversity pastoral resources, combined with management techniques farming objectives, has slowed down development digital tools assist these conditions. However, ...

Mountainous landscapes in Central Zagros are mainly used as grazing rangelands to feed animals and are heavily degraded. Overgrazing may impose a negative effect on rangeland productivity and sustainability through significant changes in soil properties. Soil nitrogen (N) mineralization is one of the key biological processes that might be affected by biotic and abiotic factors including range g...

Application of existing and novel management techniques can alter traditional livestock grazing patterns and significantly improve the sustainability of arid rangelands. Livestock often congregate and heavily graze riparian areas and other sensitive rangeland, while abundant forage remains in other areas. Increasing the uniformity of grazing can help protect fisheries, wildlife habitat, and oth...

Livestock grazing potentially has substantial influence on fuel characteristics in rangelands around the globe. However, information quantifying the impacts of grazing on rangeland fuel characteristics is limited, and the effects of grazing on fuels are important because fuel characteristics are one of the primary factors determining risk, severity, continuity, and size of wildfires. We investi...
