Welcome to CyDAS, the Cyprus Database of Alien Species

CyDAS is based on the initial work of Dr Kelly Martinou, who collated lists of alien species on Cyprus from several existing databases. See her report for more information on this work. As a part of the RIS-Ky project, we have transferred this information into a new database, with the aim of making a "one stop shop" of information on alien species on Cyprus. This database will be curated by local and international experts in the future.

This page will be updated with more information about the CyDAS database soon (e.g. the fields of the database and their associated terms); the species accounts will also become more complete as time goes on.


The CyDAS database is based on a collation of existing information by Dr Kelly Martinou. The design of CyDAS itself was led by Dr Oliver Pescott, with support from John van Breda of BiodiverseIT. John van Breda engineered the database and the web presentation. Charlotte Johns collated and reformatted the existing Martinou compilation to the new CyDAS fields and uploaded the majority of the species' data. Sara Boschi checked and formatted several new datasets from our contributors.


The initial compilation of the database is outlined by Martinou (n.d.), but included data from DAISIE, EASIN, GBIF, and data from the unpublished ELNAIS database maintained by Dr Argyro Zenetos at the Hellenic Marine Research Centre. Since this initial compilation, data has also been contributed by Nikolas Michailidis from the Department of Fisheries and Marine Research (Republic of Cyprus Government).

It is expected that the database will be continuously updated. Please contact us if you would like to contribute.


Currently the most appropriate citation for the CyDAS compilation is through GRIIS (the Global Register of Introduced and Invasive Species). However, please contact us directly if you would like an export of the latest content of CyDAS.
