This report presents the new collaborative vegetation-plot database GrassVeg.DE (EU-DE-020; http://bitly/2qgX208) which collects vegetation-plot records (releves) from grasslands and other non woodland and non-aquatic habitats from Germany to make them accessible for ecological research nationally and internationally. Data from GrassVeg.DE are provided to the European Vegetation Archive (EVA) and, in the future, also to the global database "sPlot". Data providers of GrassVeg.DE retain full copyright of their data and becomd members of the GrassVeg.DE Consortium. Thereby, they profit from their contribution via co-authorships and citations as well as the option to propose own projects using the full GrassVeg.DE or EVA data. In July 2017, the fast-growing GrassVeg.DE database contained 3,181 vegetation plots, originating from eight federal states of Germany. In the future, GrassVeg.DE could facilitate the consistent re-Classification of the grassland types within the series Synopsis der Pflanzengesellschaflen Deutschlands. We conclude the report with a call to contribute own releves and releves digitised from the literature to GrassVeg.DE.
