Database manager(s): Veronika Kalníková (v.kalnikova@seznam.cz); Helmut Kudrnovsky (alectoria@gmx.at)
Owner: Vegetation Science Group, Department of Botany and Zoology, Masaryk University
Scope: The database contains relevés of different European and Caucasian gravel bar vegetation types. It comprises the data which were digitized from the literature and data from our own field work. Most of the relevés are not stored in any other vegetation database.
