Marine Non-native species records from Natural resources Wales (NRW) monitoring research and ad-hoc sightings

Other

This dataset comprised marine surveys undertaken by the Natural Resources Wales (and previously Countryside Council for Wales) for Marine alien and non-native species, currently held in Marine Recorder. The surveys represent ongoing non-native monitoring, sightings and ad-hoc records of invasive and non-native species supplied to NRW or noted outside of other research and monitoring work. Purpose of data capture: To collate and monitor the spread of non-native around Wales and feed information into the UK non-native portal. This dataset is kept separate from others provided by NRW to allow it to be updated more often.

Methods of data capture: Field observations and incidental records taken by field staff. Presence/absence surveys of marinas around Wales.

Geographical coverage: All Wales, although the majority of data is collected for habitats know to be colonised by non-native species, such as ports and harbours.

Data quality: Not stated.
