"Background: Landscape fragmentation constitutes one of the most severe causes of global biodiversity loss.. Aims: We analyze Fagus sylvatica forests with different levels of fragmentation, addressing the following question: do the fragmented and non fragmented forests present a similar ﬂoristic composition and richness, structural parameters and ecological features?. Methods: Vascular plant species were randomly sampled based on a beech forest map classified into three fragmentation levels. We compare overall native and focal species richness patterns of the different fragmentation levels by rarefaction curves and by the ratio between focal and all species curves. We also contrast different fragmentation levels of beech forests, focusing on ﬂoristic information, structural parameters, standard ecological features and the distribution of edge and clearing species. . Results: Rarefaction analysis showed two opposite trends: the diversity of diagnostic species decreased in fragmented forests as the overall diversity increased. In more fragmented forests we found significantly higher values for therophytes and phanerophytes frequences, light Ellenberg indicator values and edge and clearing species diversity.. Conclusions: The integration of floristic analysis, particularly some diagnostic groups, with structural and ecological studies is more sensitive and significant than species richness per se and could offer a useful information for forest conservation and management..
