Physical impact of sheep grazing on arid Karoo subshrub/grass rangeland, South Africa
________________________________________________________________________________ Abstract Grazing levels and rotational schemes need to be tailored to each individual farm or pasture, and more studies are needed on the resilience of rangelands and on separating the effects of grazing and climate. The direct short-term impact of three rates of stocking (4, 8 and 16 Small Stock Units-SSU/ha) was ...
متن کاملEcogeomorphological processes within grasslands, shrublands and badlands in the semi-arid Karoo, South Africa Short title: Ecogeomorphological processes in the semi-arid Karoo, South Africa
2 Abstract Vegetation type and cover play an important role in the operation of geomorphological processes by controlling runoff and sediment dynamics. In drylands, land degradation is particularly sensitive to these eco-geomorphic interactions. Whilst many geomorphological studies of land degradation focus on the change in hydrological response as a function of vegetation cover, few have inves...
متن کاملDegradation of Non-Photosynthetic Vegetation in a Semi-Arid Rangeland
Land degradation in drylands is the process in which undesirable conditions emerge due to human and natural causes. Despite the particularly deleterious effects of degradation, and it’s potentially irreversible nature, regional assessments have provided conflicting extents, rates, and severities of degradation, both globally and regionally. Current monitoring of degradation relies upon the dete...
متن کاملForage quality of three life forms of rangeland species in semi arid and semi humid regions in different phenological stages
For determination of grazing capacity, information of forage quality is essential which is influenced by various factors. The main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. Species were two grasses (Bromus tomentellus and Dactylis glomerata), two forbs (Ferula ovina and Coronil...
