The Nationally designated areas inventory (CDDA) was formerly known as the Common Database on Designated Areas. The CDDA data is delivered by each country as spatial information (Type 1) and thematic information (Type 2). The inventory began in 1995 under the CORINE programme of the European Commission. The CDDA is now an agreed annual Eionet core data flow maintained by the European Environment Agency (EEA) with support from the European Topic Centre on Biological Diversity (ETC/BD). The dataset is used by the EEA and e.g. the UNEP-WCMC for their main European and global assessments, products and services. The CDDA is the official source of protected area information from the 38 European countries to the World Database of Protected Areas (WDPA). The CDDA data can be queried online in the European Nature Information System (EUNIS).
