Non Native Species Data - Common Slipper Shell (Crepidula fornicata) around Wales

The dataset contains a series of records of the non-native slipper limpet Crepidula fornicata, around Wales. The records have been extracted from the Phase 1 Intertidal survey from target notes and site species lists and collated with ad-hoc records recorded by Countryside Council for Wales (CCW) staff or supplied by third parties, along with records extracted from CCW's Marine Recorder data holdings. The purpose of this collation is to monitor the spread of non-native marine species across Wales.
