Apart from their exotic names, these species all have something else in common: they are all aliens which have or could be recorded in North Wales! Together with many other introduced species they pose a threat to our native wildlife. That's why the North Wales and Dee Invasive Non Native Species Forum have picked these species for their 'Record An Alien' project, hosted by Cofnod.

Knowing where these species occur will help stop their spread. So if you've seen any of these Aliens, please submit the record to us, ideally using our Online Recording System (more details below). Otherwise you can email us or use our standard recording spreadsheet (see the Submit Records page). Please submit records of Chinese Mitten Crab using the new Mitten Crab Recording Project website.
