GIVD Database ID: EU-DE-013	Last update: 2019-08-28
VegetWeb Germany	Web address: https://www.vegetweb.de/
Database manager(s): Florian Jansen (florian.jansen@uni-rostock.de); Jörg Ewald (joerg.ewald@hswt.de)
Owner: Federal Agency for Nature Conservation, Working Group Vegetation Databases
Scope: Central Vegetation Database of Germany. Designed to collate all available vegetation data within Germany. Capable of different taxon concepts. Import possibility from Turboveg (XML)
Abstract: VegetWeb is an online archive for vegetation plot data from Germany and can be viewed through the website FloraWeb. The data model of VegetWeb allows upload, storage and interactive search of plot data with different original formats and taxonomic reference. Due to lack of funding only a small proportion of Germany's legacy of plot data has been captured so far. VegetWeb co-operates with the journal Tuexenia, for which it provides an interactive online archive of relevé tables by capturing and distributing all newly published data.
