Abstract: The Hellenic Woodland Database (GIVD ID EU-GR-006) includes relevés from 59 sources, approximately, as well as unpublished relevés. In total 4,571 relevés have already been entered in the database, but the database is going to continue growing in the near future. Species abundances are recorded according the 7-grade Braun-Blanquet scale. The oldest relevés date back to 1963. For the majority of relevés (more than 90%) environmental data (e.g. altitude, slope aspect, inclination) exist. Relevés entered in the database represent both evergreen and deciduous forests, as well as scrubs and they belong (according to the original publications) to the classes Quercetea ilicis, Rhamno-Prunetea spinosae, Erico-Pinetea, Quercetea pubescentis, Querco-Fagetea, Vaccinio-Piceetea and Populetea albae. Most relevés (approximately 69%) concern northern Greece (floristic regions of northeastern, north-central Greece and northern Pindos), while the remainder concern the rest of Greek mainland as well as the islands.
