Countryside Council for Wales (CCW) Freshwater Fish Ad-hoc Records for Habitats Directive (Council Directive 92/43/EEC) Reporting under Article 17

Natural Resources Wales

Description

Freshwater fish species records collected by CCW staff, contractors or members of the public. N.B. this dataset is an interim upload to allow Article 17 reporting to be completed. The data are being entered into Marine Recorder and a regular export will be carried out once this is complete. This export will replace this dataset.

This dataset is a collation of records that constitutes a gap filling exercise rather than a coherent dataset in itself. Consequently it should not be viewed as being spatially or temporally representative. However, it may be used in combination with other data to make assessments of the range and / or occurrence of relevant species. We have high confidence in the taxonomic quality of the records.

Geographic Description

All Wales.

Purpose

There are numerous reasons for this data capture. This dataset is a compilation of numerous records from different sources complied for Habitats Directive Article 17 reporting, related to freshwater fish species. 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.

Data quality

This dataset is a collation of records that constitutes a gap filling exercise rather than a coherent dataset in itself. Consequently it should not be viewed as being spatially or temporally representative. However, it may be used in combination with other data to make assessments of the range and / or occurrence of relevant species.

We have high confidence in the taxonomic quality of the records.

Methods

There were numerous methods of data capture including formal site condition assessments, monitoring through surveys, and a compilation of ad hoc records. This dataset includes records collected by various methods, including hydroacoustic monitoring, netting, electrofishing and visual surveys. Records come from various sources, including members of the public. These records in particular are normally validated with photographic or video evidence. Survey effort varies greatly and the dataset should not be assumed to be statistically representative. National Grid References (NGRs) have been reported to the highest level of accuracy, where available. In most cases this is 6 figures or more (e.g. AB123456).
