Scope: All vegetation plot records from the Czech Republic.
Abstract: The Czech Vegetation Database (formerly the Czech National Phytosociological Database) was established at Masaryk University in Brno in 1996. 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 sampled across the territory of the Czech Republic. The data stored in the database were used for the development of the national vegetation classification of the Czech Republic, and currently, they are used for biodiversity analyses at local, regional, national, and international levels, as a source of information about the distribution of plant communities and species, and for the assessment of vegetation change. The database also contains small number of vegetation plots from neighboring countries (Slovakia 1%, Austria, Poland and Germany < 1%), which are not included in the statistics. The complete data from the Czech Republic are freely available online at https://czechveg.github.io/ and in the GBIF database (https://doi.org/10.15468/94bfqd).
