Biological invasions by non-native or 'alien' species are one of the greatest threats to the ecological and economic well-being of the planet.. Alien species can act as vectors for new diseases, alter ecosystem processes, change biodiversity, disrupt cultural landscapes, reduce the value of land and water for human activities and cause other socio-economic consequences for man.. To help those tackling the invasive species challange, this website provides a 'one-stop-shop' for information on biological invasions in Europe.. This website is the result of the DAISIE project, funded by the European Commission under the Sixth Framework Programme (Contract Number: SSPI-CT-2003-511202).

The current version is only provisional for invertebrates and fungi where a large amount of data is currently being incorporated and corrections are being made.
