Name ETC delivery Common Database on Designated Areas (CDDA)
Short Description Dataservice definition: The dataset contains data on individual nationally designated sites and designations in EEA member and collaborating countries.
Definition Updated European inventory of nationally designated areas is a delivery prepared annually (or as decided) by the European Topic Centre on Biodiversity. The dataset is a result of processing and merging of latest quality assured national CDDA deliveries, collected under the CDDA data collection process and of latest updated delivery of data from WDPA. After it is approved by the EEA the dataset is published via the EEA Data Service web site.
Methodology for obtaining data This dataset is based on the Data Dictionary dataset CDDA (

All CDDA data reported by countries under the ROD obligation Nationally designated areas (CDDA-1) in the CDR ( or national repositories are to be processed, quality assured and merged into one, European dataset.

It is expected that the national data reporters use for the reporting the latest Microsoft Access templates pre-filled with the data reported by country last time. If the data is reported differently (old templates, different file formats etc.), and country do not properly redeliver the data on a request, the ETC data managers should anyway try to transfer as much data as possible into the proper structure. They have to however keep in mind the reporting deadlines and do not spend too much time waiting for the redelivery or by processing of data of inconsistent quality or delivered in incompatible structure.

The complete and updated European dataset is to be created by the responsible ETC data mangers by importing the quality assured data into Microsoft Access template, which is downloadable here in the Quick links section. The structure, data definitions or functionality of the template can not be modified.

Important: Sites and designation records flagged by the reporters for deletions are to be kept in the European datasets as these are used in further QC, to generate data quality reports and to update CDDA Site code vocabulary.

The delivery is to be then upload to Reportnet SVN Workdata repository:
