Abstract

The need for a classification of the vegetation of the fynbos region is stressed. In the present work we have evaluated some structural-functional approaches that could be used to classify and describe fynbos.  A priori and  a posteriori approaches to classification are reviewed. The a posteriori approach appears to be superior.Test data derived from 21 plots from a range of fynbos types were used to test some methods of collecting and analysing structural-functional information for an  a posteriori  classification. With respect to data collection, no single method was superior. However, a major improvement on our methodology would be possible if the growth-form system used were to be extended. The classifications that were erected were produced by means of computer-based numerical methods. These methods are essential if large data sets are to be analysed. However, the structural-functional classifications produced by numerical methods should only be regarded as working hypotheses; refinement of the classifications should proceed by intuitive methods. We feel that the a posteriori approach, even though it has its problems, will provide a suitable methodology for an ecologically meaningful classification of fynbos vegetation.
