Grazing-index method procedures of vegetation surveys
AbstractIn the past, veld condition in the Karoo was assessed using the ecological index methods. This recently changed to the graxing-index method on account of the of the differently estimated grazing-index values being used. The principles governing the method of survey remain the same. The method employs canopy-spread-cover strikes to record the species composition of different sites. By appropriate management of these line point data, different sites can be compared with one another by emplying the Z-index of agreement(similarity).
