| Résumé : |
"The vegetation relevés stored electronically in the Czech National Phytosociological Database arereviewed. The database was established in 1996, with the central database located in theDepartment of Botany, Masaryk University, Brno (www.sci.muni.cz/botany/database.htm). On 15November 2002 this central database contained 54,310 relevés from the Czech Republic, collectedby 332 authors between 1922–2002. Ca. 54% of the relevés were taken from published papers ormonographs, 21% from theses and the rest from various unpublished reports and field-books. Theserelevés include 1,259,008 records of individual plant species. Territorial coverage of the country bythe reléves is irregular as the areas with attractive natural or semi-natural vegetation are moreintensively sampled, with gaps in coverage of less attractive or poorly accessible areas. Mostrelevésareofbroad-leaveddeciduousforests(Querco-Fagetea),meadows(Molinio-Arrhenatheretea), dry grasslands (Festuco-Brometea), and marsh grasslands (Phragmito-Magnocaricetea). The quality of the data is discussed, such as researcher bias, preferentialselection of sampling sites, spatial autocorrelation and missing values for some data elements" |
