Six rivers in Wales, including the Afon Tywi in West Wales, are designated as Special Areas of Conservation (SACs) for lamprey species. Natural Resources Wales is responsible for monitoring the condition of lamprey populations within SACs and ensuring the maintenance of favourable conservation status at designated sites. The data, originally collected under contract for the former Countryside Council for Wales, are used to assess the population attributes of all three lamprey species. Sampling was carried out between 5 October and 22 November 2011. A total of 30 survey sites were selected across the Tywi catchment between Llandovery and Carmarthen.
