Scope: All phytosociological relevés and related vegetation plot records from the Czech Republic.
Abstract: The Czech National Phytosociological Database was established in 1996 at Masaryk University in Brno. Currently it is hosted by the Department of Botany and Zoology of this university. It is an electronic archive of phytosociological relevés and related records of species composition from vegetation plots which have been sampled on the territory of the Czech Republic. The data stored in the database are used for the development of new national vegetation classification of the Czech Republic, biodiversity analyses at local, regional, national and international level, as a source of information about distribution of plant communities and species, and for development and testing new methods of analysis of large sets of vegetation-plot data.
