NBGVD - Nordic-Baltic Grassland Vegetation Database (EU-00-002)
Originally, this database was named "Database Dry Grasslands in the Nordic and Baltic Region" (with a slightly narrower scope). Now all available relevés of natural and semi-natural grasslands in the widest sense and related communities from the study region (Denmark, Faroer Islands, Iceland, Norway, Sweden, Finland, Svalbard and Jan Mayen, NW Russia, Belarus, Estonia, Latvia*, Lithuania*, N Poland*, NE Germany*) are collected (* = new data from these countries are meanwhile collected by specialised national databases). Basically this means the phytosociological classes Festuco-Brometea, Koelerio-Corynephoretea (including Sedo-Scleranthetea), Molinio-Arrhenatheretea, Juncetea maritimi (including Saginetea maritimae), Ammophiletea arenarii (incl. Honckenyo-Elymetea), Juncetea trifidi, Carici-Kobresietea, Calluno-Ulicetea (including Nardetea strictae), Loiseleurio-Vaccinetea, Salicetea herbaceae, Scheuchzerio-Caricetea fuscae, Trifolio-Geranietea sanguinei (including Melampyro-Holcetea) and Mulgedio-Aconitetea. However, if a certain source also contains a small amount of other vegetation types, they are also accepted.
NBGVD is a collaborative database, self-governed by the data contributors who become members of the NBGVD Consortium according to the NBGVD Bylaws. The data of NBGVD are contributed to the European Vegetation Archive (EVA) and the global vegetation-plot database sPlot, thus making the Nordic-Baltic data available for supraregional analyses (with opt-in authorship options for NBGVD members) while at the same time providing access to these megadatabases to its members. Persons with suitable plot data are invited to join.
