La végétation des sources thermominérales salées d’Auvergne

The authors accomplish a phytosociological study of the salt thermomineral spring vegetation in Auvergne. They follow a ‘braun-blanqueto-tuxenian’ approach of the association. Despite a large number of releves carried out on the salty sites of Auvergne, the communities stay unknown as it seems necessary to synthesize them and clarify their phytosociological status.The authors carry out an analysis and a synthesis of 176 phytosociological releves illustrating the communities of the twenty salty localities known in Auvergne. From 16 sites, 69 releves were specifically produced as part of this study.Nine communities are presented on the floristical and synecological plan : three new associations and six new sub-associations are described.
