Aderyn :: Home

Welcome to Aderyn: the Biodiversity Information and Reporting Database of Local Environmental Records Centres Wales. Here you can access wildlife sightings and species records collated by the four LERCs, covering the whole of Wales. Anyone can use this site to view lists of species recorded around their home or maps showing the distribution of species according to data held by LERC Wales. Partners, recorders and planners can be licenced to access high resolution, detailed records to assist decision making and conservation.
