First phases of regeneration in three types of heath communities after fire, cutting and uprooting in experimental plots have been studied, devoting a particular attention to the herbaceous species. Greater rate of perennial than annual species has been observed in most of the burned and cut plots and still no regeneration response in most of the uprooted ones. Diversity, richness, evenness and heterogeneity values have been analysed. The regeneration response after the different process has been compared by affinity analysis.
