The European inventory of Nationally designated areas (CDDA) holds information about designated areas and their designation types, which directly or indirectly create protected areas. The inventory is delivered by the Eionet partnership countries as spatial and tabular information. 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 39 European countries to the World Database of Protected Areas (WDPA). The CDDA data can be queried online in the European Nature Information System (EUNIS). Geographical coverage of GIS vector boundary data: Albania, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo under UNSC Resolution 1244/99, Latvia, Liechtenstein, Lithuania, Luxembourg, North Macedonia, Malta, Montenegro, the Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom. The dataset ("CDDA_2019_v01_internal") includes the entire geographical coverage including nationally designated areas in overseas entities and is provided in GDB and GPKG formats. NOTE: EEA does not have permission to distribute some or all sites reported by Estonia, Finland, Ireland and Turkey. Therefore, this data set is available only for internal use of the European Environment Agency. The public version dataset is available with the title "Nationally designated areas (CDDA) polygons for public access - version 17, June 2019", which is derived from this dataset.

Riparian zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water. They provide a wide range of riparian functions (e.g. chemical filtration, flood control, bank stabilization, aquatic life and riparian wildlife support, etc.) and ecosystem services. The Riparian Zones products support the objectives of several European legal acts and policy initiatives, such as the EU Biodiversity Strategy to 2020, the Habitats and Birds Directives and the Water Framework Directive. Land Cover/Land Use (LC/LU) classification is tailored to the needs of biodiversity monitoring in a tailored buffer zone along large and medium-sized European rivers (with Strahler levels 3-8 derived from EU-Hydro). LC/LU is extracted from VHR satellite data and other available data in a buffer zone of selected rivers. The classes follow the pre-defined nomenclature on the basis of MAES typology of ecosystems (Level 1 to Level 4) and Corine Land Cover, providing 80 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The production of the Riparian Zones products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme.

Two versions of the dataset are provided. The "CDDA_2018_v01_internal_EuropeEPSG3035" version includes only continental Europe, i.e. excludes the overseas entities. The full dataset ("CDDA_2018_v01_internal") includes the entire geographical coverage including nationally designated areas in overseas entities. Both versions are provided in GDB and GPKG formats.

Riparian zones represent transitional areas occurring between land and freshwater ecosystems, characterised by distinctive hydrology, soil and biotic conditions and strongly influenced by the stream water. They provide a wide range of riparian functions (e.g. chemical filtration, flood control, bank stabilization, aquatic life and riparian wildlife support, etc.) and ecosystem services. The Riparian Zones products support the objectives of several European legal acts and policy initiatives, such as the EU Biodiversity Strategy to 2020, the Habitats and Birds Directives and the Water Framework Directive. Green Linear Elements (GLE) are ecologically significant, structural landscape elements which act as important dispersion vectors of biodiversity. GLEs comprise hedgerows and lines of trees and offer a wide range of ecosystem services: they are linked to both landscape richness and fragmentation of habitats, with a direct potential for restoration, and contribute also to hazard protection. Green linear elements form part of the Green Infrastructure and are specifically addressed in the EU Biodiversity Strategy 2020. The GLE product provides reliable and detailed geospatial information on the occurrence and spatial distribution of: Small linear vegetation features such as hedgerows, scrub and tree rows with a minimum length of 100m and a width of up to 10m; Isolated patches of trees and scrub with a size between 500 m² and 0.5 ha. Green linear elements including trees and hedgerows with 100m minimum length and 500 m² Minimum Mapping Unit (MMU). The production of the Riparian Zones products was coordinated by the European Environment Agency in the frame of the EU Copernicus programme.

EEA does not have permission to distribute some or all sites reported by Estonia, Finland, Ireland and Turkey. The public version dataset is available with the title "Nationally designated areas (CDDA) for public access - version 18, May 2020", which is derived from this dataset. Two versions of the dataset are provided. The full dataset ("CDDA_2020_v01_internal") includes the entire geographical coverage including nationally designated areas in overseas entities. The "CDDA_2020_v01_internal_EuropeEPSG3035" version includes only continental Europe, i.e. excludes the overseas entities. Both versions are provided in GDB and GPKG formats. The dataset is accompanied by the following tabular data: CDDA_2020_v01_internal_DesignatedArea.csv, which includes information on all the nationally designated sites and designated boundaries; and CDDA_2020_v01_public_DesignationType.csv, which contains information about designation types and the national and international legislative instruments, which directly or indirectly create protected designated areas in Europe.

The vector dataset presents the percentage of green space in densely built-up areas for a series of individual European cities (included in Urban Audit) for the year 2012. The presence and proportion of green space in densely built-up urban areas is an important aspect of adaptation to climate change. Green space regulates the microclimate of the city, reducing the temperatures. It also reduces the risk of flooding related to heavy precipitation, as vegetation and permeable surfaces retain and infiltrate rainwater, reducing the amount that comes into the drainage system. Data on green space was obtained from Copernicus Urban Atlas 2012, extracting the Urban Atlas classes treated as green space. The Urban Morphological Area (UMZ) dataset for 2012 and the Eurostat Urban Audit dataset (polygon, 2011-2014) were been used to calculate the total area within the core city. The values were then allocated to the city centroids from the same Eurostat Urban Audit dataset.
