Range exclosures have been used as a tool to restore degraded communal grazing lands in Tigray region of Northern Ethiopia. Although there seems be ecological evidence success rehabilitation rangelands Tigray, is unclear translation these achievements into socio-economic benefits. It was hypothesized that this could partly attributed poor governance the range occasioned by low participation and...
Gullies are sources and reservoirs of sediments perform as efficient transfers runoff sediments. In recent years, several techniques technologies emerged to facilitate monitoring gully dynamics at unprecedented spatial temporal resolutions. Here we present a detailed study valley-bottom in Mediterranean rangeland with savannah-like vegetation cover that was partially restored 2017. Restoration ...
Abstract Herbivores form an important link in the transfer of energy within a food web and are strongly influenced by bottom‐up trophic cascades. Current hypotheses suggest that herbivore consumption impact on plants should scale positively with plant resource availability. However, depending effect resources quantity quality, may vary different types resources. We test four alternative for rel...
The extent of rangeland is one of the most important characteristics of organic carbon uptake and storage in soil and plants. The present study investigates the indices of plant diversity and organic carbon storage in mountain pastures under grazing and 10-year enclosure in Asadabad. The rangeland is approximately 100 hectares and its rangelands are in good condition and are in the 2S class in ...

subalpine ecosystems are highly fragile as compared to biological andenvironmental factors. landslide is one of the ruinous upshots of this ecosystem. one of theimpressionable areas in the cause of natural factor is masoleh watershed in western alborzmt, (iran). in order to landslide hazard zonation, landslide index and frequency ratio methodbased on twelve causative factors such as slope, slop...
Restoration of degraded grasslands through improved management is among the possible sustainable solutions to compensate for anthropogenic soil carbon (C) emissions. While several studies have shown a positive effect rehabilitation on C, impact CO2 emissions still uncertain. Therefore, this study aimed at quantifying grassland in grassland, South Africa. Commonly used practices were considered,...
