After this group held its facts and views on the mechanisms of vegetation dynamics. final meeting two years earlier it decided to continue its Then a group of contributions follows in which data on species behaviour, plant demography and diversity during activities, but in a wider scope. Most members of the succession are discussed. This includes Faliriski's study on Group felt that the original aim, i. e. the introduction of data-processing and multivariate methods for use in the sex structure and dynamics of pioneer woody species, a systematic description of plant communities, was more or fynbos diversity study by Campbell & van der Meulen and less fulfilled.
