This dataset is a compilation of numerous records from different sources complied for Habitats Directive Article 17 reporting, related to freshwater pearl mussels Margaritifera margaritifera. Every six years, Member States of the European Union are required (by Article 17 of the Directive) to report on implementation of the Habitats Directive. The reporting format set by the European Commission requires a separate analysis for each species and each habitat in each biogeographic region which that country covers. This dataset comprises of Environment Agency and Countryside Council for Wales surveys. The aim of this collation has been to ensure that the 10 km distribution maps on the NBN accurately reflect the known position of this species. Records have been compiled with this in mind and hence no attempt has been made to collate every single record for each 10km square within the designated time period.

The sensitive data is as follows - location of Pearl Mussels. 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 Data Distribution Team. Data may be released freely if the sensitive records are removed in advance, or shown only at a coarser scale. no limitations © CNC/NRW 2008 Recipients may only re-use sensitive data in strict confidence under the terms of an appropriate NRW Licence or equivalent. No publication or dissemination is permitted, except if sensitive records are removed in advance, or shown only at a coarser scale. At a spatial scale at which the records are considered non-sensitive then there are no use restrictions on this data, including for commercial and research purposes. Recipients may re-use, reproduce, disseminate this data free of charge in any format or medium, provided they do so accurately, acknowledging both the source and NRW's copyright, and do not use it in a misleading context.

Records are taken from CCW’s biological database and the Environment Agency (Wales) GIS system and relate to in-house and contracted surveys of Welsh rivers carried out in the past eight years. Surveys have been undertaken as part of monitoring programmes and Wales-wide distribution surveys. The majority of records in this dataset are collated with six or eight figure grid-references, although where surveys have reported on individual river sections then four-figure references may have been used. The dataset represents the distribution of the pearl mussel across Wales during the data capture period.
