Czech National Phytosociological Database
The aim of the Czech National Phytosociological Database is to gather computerized vegetation-plot data (phytosociological relevés) from the territory of the Czech Republic in a large database, which will facilitate easy access to relevant data for the purposes of vegetation survey, ecological analyses and applications in nature conservation. These activities are a part of wider European projects co-ordinated by the Working Group for European Vegetation Survey of the International Association for Vegetation Science.
The data are stored in the TURBOVEG database management program developed by Stephan Hennekens, which is a European standard software for phytosociological databases. Current network of Czech TURBOVEG users was established with the help of the UK Government funding for the Darwin Initiative project "Safeguarding the Biodiversity of Eastern Europe" (1995–1998), co-ordinated by John Rodwell at Lancaster University, UK. Since 1999 the database project has been funded from various projects of Masaryk University, most of them provided by the Czech Science Foundation.
The Czech National Phytosociological Database is co-ordinated at the Department of Botany and Zoology, Masaryk University, Brno, with several local co-ordinators in other academic institutions in the Czech Republic. The co-ordinators of the database are Milan Chytrý (chytry_at_sci.muni.cz) and Dana Michalcová (danmich_at_sci.muni.cz). An integral part of the database project is the development of methods for data analysis. Major procedures developed so far are available in the JUICE software developed by Lubomír Tichý.
Current state of the database
On 26 January 2012 the central database contained 98 098 relevés from the territory of the Czech Republic. Most relevés belong to phytosociological classes of broad-leaved forests (Querco-Fagetea), meadows and mesic pastures (Molinio-Arrhenatheretea), marshes (Phragmito-Magno-Caricetea), dry grasslands (Festuco-Brometea) and disturbed vegetation of wet to mesic habitats (Galio-Urticetea). Phytosociological bibliography of the Czech Republic, with indication which data have been included in the database, is available here.
Relative number of relevés (17 March 2010)
Nomenclature of vascular plant species in the Czech National Phytosociological Database follows an updated version of Liste der Gefäßpflanzen Mitteleuropas (Ehrendorfer 1973), prepared by Harald Niklfeld and Walter Gutermann, with additions of species included in Key to the flora of the Czech Republic (Kubát et al. 2002). Names of bryophytes and lichens follow Frey et al. (1995) and Pišút et al. (1993). Species list used in the Czech National Phytosociological Database, called Czechia_Slovakia_2010, is identical with that used in the Central Database of Phytosociological Relevés in Slovakia. The list of syntaxa used in the Czech installation of TURBOVEG is according to Moravec et al. (1995).

There are three regimes of data availability:
- Free data available online
- Data available upon request from database managers for the purposes of academic research or applications in nature conservation, but not for commercial purposes. Data requests should be sent by e-mail to Dana Michalcová (danmich_at_sci.muni.cz) or Milan Chytrý (chytry_at_sci.muni.cz) with a description of the intended use of the data and criteria of data selection (e.g. area, vegetation type and time period) and the required format.
- Non-public data which are stored in the central database but not made available to the public, or made available only for specific purposes specified by the data provider.
Data use in publication should be acknowledged using the standard database citation:
- Chytrý & Rafajová (2003): Czech National Phytosociological database: basic statistics of the available vegetation-plot data. Preslia 75: 1–15.
At the same time the papers where the data were published or authors of unpublished data should be cited. These citations can be omitted if a set of data from many different sources is used in which no source is notably prevailing, and if the type of publication does not allow citing all the sources (e.g. papers with restriction on the number of references used).
Other vegetation databases
An overview of vegetation databases over the world is available in the Global Index of Vegetation-Plot Databases (GIVD). A list of European databases including contact information is available here.
