Abstract
Uittreksel
‘n Proef is uitgevoer om vas te stel wat die onmiddellike uitwerking van intensiewe beweiding op die plante‐groci, die proefdicre (Merino‐ooie) en die grand oppervlakte is. Twaalf proefkampe is gebruik en bewei teen ‘n vcebelading van 20 skaap per morg vir 14 of 15‐dae periodes per kamp. Die vernaamste resultate hot gewys dat die skape in staat was om die bodem‐, kroon, en kvoonuitgestrektheidsbedekkings betekenis‐vol te verminder. Die verskillende spesies is nie in dieselfde mate afgevreet nie. Die vertrapping en ver‐steuring van die grondoppervlakte en voetpadvorming was die mees opsigtelike kenmerk na intensiewe beweiding. In hierdie stadium word dit beskou as die grootste nadeel van die toepassing van hierdie beweidingsmetode. Geen nadelige nitwerking kon op die proefdiere bespeur word nie.
Abstract
An experiment was carried out to determine the immediate effects of intensive grazing on the vegetation, the grazing animals (Merino ewes) and the soil surface. Twelve experimental camps were used and grazed at a stocking density of 20 sheep to the morgen for 14 or 15 days per camp. The results showed that the sheep were capable of reducing the basal, canopy, and. canopy‐spread cover significantly. The various species were not all grazed to the same extent. The trampling and disturbing of the ground surface, and footpath formation, were the most conspicuous effects of intensive grazing. At this stage this is regarded as the greatest drawback in the application of this method of grazing. No harmful effects could be seen on the grazing animals.
