UK Biodiversity Action Plan Invertebrate Data for Wales

Quality Control

Data accuracy is reliant on original sources. Spatial references, dates and species identifications have been validated by NRW's invertebrate experts checking printed lists of records, and literature references have been added where possible.

Method steps

1. The dataset is a sub-set of the Welsh Invertebrate Database (WID). WID is a collation of records from many available sources, including literature records, published surveys and information submitted by naturalists. Records including negative occurrences where the species has been specifically searched for without success are noted. The complete database contains third party data and NRW is working towards the release of the full database.

All Wales. The majority of the records are available at a precision of between 4 and 6 figure grid references.
