Abstract
The long term effects of continuous grazing by Merino sheep and Angora goats and complete protection on short Karoo shrubveld of the Central Lower Karoo were investigated.
Botanical surveys were done by means of the wheel point method. For statistical analysis the vegetation was grouped into ephemerals, grasses, Karoo shrubs and succulent shrubs each with sub‐classes of palatable and unpalatable.
The results showed that continuous grazing by goats at a realistic stocking rate was less harmful to the palatable perennial component of the vegetation than was continuous grazing by sheep. Complete protection over a period of 11 years resulted in a sustained improvement in the perennial palatable component, thus demonstrating the advantages of a long rest for Karooveld.
Uittreksel
Die langtermyn uitwerking van aanhoudende beweiding deur Merinoskape en Angorabokke en algehele beskerming op kort Karoobossieveld van die Sentrale Laer Karoo is ondersoek.
Botaniese opnames is gedoen volgens die wielpunt metode. Vir statistiese verwerking is die plantegroei onderverdeel in opslagplante, grasse, Karoobossies en sukkulente bossies met sub‐klasse van smaaklike en onsmaaklike vir elke klas.
Die resultate het getoon dat aanhoudende beweiding met bokke teen ‘n realistiese drakrag baie minder skadelik vir die meerjarige smaaklike komponent van die plantegroei was as aanhoudende beweiding met skape. Algehele beskerming het oor ‘n periode van 11 jaar volgehoue verbetering van die meerjarige smaaklike komponent tot gevolg gehad en die voordele van ‘n lang rus vir Karooveld beklemtoon.
