Effets de la fauche tardive sur la diversité végétale des bords de routes de la Communauté

Abstract : Today, the urban managers are more and more involved in the management of the roadsides and handle this with the objective to promote the biodiversity. The exporting late mowing seems to be the best way of managing. The main purpose of this study was to quantify the plant diversity of the roadsides which are handled in late mowing within the urban Community of the Grand Nancy. The second purpose was to visualize the evolution of this diversity in time and space in order to understand the dynamics in plant communities, supplementing the taxonomic approach by a functional approach. The presence of a great taxonomic diversity in road edges could be emphasized by various indices of diversity: Shannon-Wiener (H’), species richness (S), equitability (D), Sorensen (S8). The study of the functional diversity has been carried out on three main easy traits: SLA (Specific Leaf Area), LDMC (Leaf Dry Matter Content) and the height of the plants. It helped to confirm the importance of light in the dynamics of the plant communities. Nevertheless, other factors which play an important role in communities’ assembling in the roadsides still remain to be discovered and clarified.
