Access data
Availability: Restricted
The data are withheld from general circulation and disclosure but access may be obtained on a case-by-case basis through negotiation

Notes: Part of this dataset is sensitive and restricted. The sensitive data is as follows: o King Scallop Pecten maximus (below 10km square) o Queen Scallop Aequipecten opercularis (below 10km square) o Native Oyster Ostrea edulis (below 10km square) o Crayfish Palinurus elephas (below 10km square) o Seahorse Hippocampus guttulatus (below 10km square) o Short snouted seahorse Hippocampus hippocampus (below 10km square) o Grey seal Halichoerus grypus (below 5km square) o All cetaceans (below 10km square) o Oyster bed habitat IMX.Ost (biotope code) (below 20km square) Sensitive data must be kept confidential; general release is not permitted due to risk of harm to the environment or third parties. Sensitive data may only be released under an appropriate NRW Licence. Requests should be referred to NRW's Access to Information Officer. Data may be released freely if the sensitive records are removed in advance, or shown only at a coarser scale.

Description
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. more

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.
