Grazing-index method procedures of vegetation surveys


PCV du Toit

Abstract

In 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).
