Natural Resources Wales Regional Data : Mid-Wales

Quality Control

Records are validated for geographical area on import to BIS database. BIS makes every effort to exchange with county recorders for verification but due to the historical nature of this dataset some records remain unverified. Data will have been collected by local experts, ecological consultants, ecologists and members of the public.

Method steps

1. This dataset was created from species records extracted, computerised and collated from paper records held at CCW's Regional office files covering the Powys and Brecon Beacons National Park area. The work was carried out under contract by BIS staff members within the CCW offices between 2003 and 2009, as part of CCWís Data Mobilisation Project. However, coverage was not complete, as follows:- Newtown: completed 10Km square files and partial completed SSSI files, Llandrindod Wells: General files complete. All SSSI files complete Abergavenny: 10km square files complete. SSSI complete. SAC and NNR files not completed Records were entered into Recorder 2002 or Recorder 6 databases. The material from which records were derived included the following: reports, site registers, recording cards, protected site condition assessments, Phase 1 and Phase 2 habitat surveys, other general survey work and records of casual observations. Numerous biological recording techniques and survey methodologies were used in the collection of these records. Some of the records were produced by former CCW staff or by qualified contractors working on CCW's behalf whilst some records have been provided by third parties, or derived from documents, surveys or datasets produced by others, but held in CCW files. Due to the nature of the files and the lack of documentation it has not been possible to determine what proportion of the records within the dataset are NRW owned against third party data. Data also includes species records from NRW Phase 1 target notes for Breconshire, Montgomeryshire and Radnorshire digitised within BIS offices, not under contract.

Area covered is Powys and the Brecon Beacons National Park.
