Marine Non Native Species records from Natural Resources Wales (NRW) Monitoring Research and Ad-hoc Sightings
This dataset comprises of marine surveys undertaken by the Natural Resources Wales (NRW) (and former Countryside Council for Wales) for Marine non-native species, currently held in Marine Recorder. The surveys represent on-going non-native monitoring, sightings and ad-hoc records of invasive and non-native species supplied to Natural Resources Wales (NRW) or noted outside of other research and monitoring work.
All Wales, although the majority of data is collected for habitats know to be colonised by non-native species, such as ports and harbours.
The purpose of this data capture was to collate and monitor the spread of non-native species in Wales. These collations of datasets contains records specifically for Sargassum muticum around Wales, and ad hoc macro-algae invasive species around Welsh marinas and invasive crab species within the Dee Estuary.
The majority of the data where recorded by experienced staff or are verified with known experts and staff through the use of photographs, video or specimens, however volunteer records are also included.
Field observations and incidental records taken by field staff. Presence or absence surveys of marinas around Wales. Fyke netting within estuaries.
