All sensitive species records, collated from species records mobilised from former Countryside Council for Wales regional files, held at Newtown, Abergavenny and Llandrindod Wells offices.Purpose
To mobilise a valuable data resource in order to provide baseline data to inform conservation work, research, site management and decision-making within CCW and externally.Sampling Description
Quality Control
The majority of the records were created by CCW staff, qualified contractors or other trusted sources and are generally of a good standard.Some of these records have been subject to external verification including plants, bryophytes, dragonflies and moths but many have not been subject to systematic external verification.
The computerisation of these records has been subject to validation. The Recorder database automatically validates issues such as date format, correct species name spelling etc on entry. The spatial reference (grid reference) has been validated against GIS, to check that it matches location name and is within designated site boundary (if appropriate). Outliers have been removed. Many records have been checked against BIS's main database to avoid duplication.
Data operators were trained by BIS, had biological/ecological backgrounds and had access to CCW staff for checking queries. They also checked their own entries for accuracy.
Data should be checked against original sources before use in contentious circumstance.
Method steps
-
This dataset was created from species records extracted, computerised and collated from paper records held at former CCW's Regional office files covering the Powys and Brecon Beacons National Park area.
The work was carried out under contract by ten BIS staff members within the CCW offices between 2003 and 2009, as part of CCWs 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 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 CCW owned against third party data. Data also includes species records from CCW Phase 1 target notes for Breconshire, Montgomeryshire and Radnorshire digitised within BIS offices, not under contract.
Taxonomic Coverages
Geographic Coverages
The majority of records are from Powys and Brecon Beacons National Park or within a 5km buffer.
Many records are for designated sites (including SSSIs, SACs, National Nature Reserves etc), however, there are also large numbers of records from the wider countryside.
The grid references entered will be at resolution of original record and could be 2 or 4 figures, however, the majority of the records have 6 figure grid-references. Some grid references may be from site centroids rather than actual location of the species in question or may have been estimated from map. The resolution of these records have been reduced in this data set as shown under 'Access constraints'
