Scope: The European Weed Vegetation Database consists of vegetation relevés from the European continent, the great majority of which is not yet included in other registered databases. The main scope represents annual vegetation of the cultivated land and ruderal places. Additionally some other vegetation types are included when they were published in the same publication or the stands were of transitional type (e.g. Artemisietea vulgaris, Polygono-Poetea, Epilobietea angustifolii, Molinio-Arrhenatheretea ...)
