In this paper we describe the historical background and contents of the DUMIRA vegetation plot database (GIVD-code EU-NL-003). It contains 13,046 relevés, collected between 1995 and 2018 at military ranges in the Netherlands, and it is updated regularly with new data. Historical circumstances led to the placement of military ranges at the most nutrient poor, dry, sandy soils, and as a result, the database is built up mainly by plots of Calluno-Ulicetea and Nardetea heathlands, Koelerio-Corynephoretea grasslands, and Quercetea robori-petraeae woodlands. These classes account for more than 50% of the database. Coastal communities (e.g. from the Juncetea maritimae and the Therosalicornietea) and scrubs (e.g. the Lonicero-Rubetea plicati and Salicetea arenariae) are other important sources. Notably, throughout the database, Rubus species are identified to species level. Although the DUMIRA database was initially used for management related vegetation mapping projects, the data gave rise to several more scientific studies and papers. Taxonomic reference: Van der Meijden (2005) for vascular plants; Van de Beek et al. (2014) for Rubus; Kleukers et al. (2004) for Orthoptera. Syntaxonomic reference: Mucina et al. (2016).
