Coastal saline lagoons are an unusual and rare habitat in the UK, where they are recognized as a \key\" habitat under the Biodiversity Action Plan. The EC Council Habitats Directive on the conservation of natural habitats and of wild fauna and flora identified coastal lagoons as a priority habitat. Work carried out identified 14 saline or potential saline lagoons and ponds in Wales four of which are identified as of high conservation merit. The extent of these lagoons have been mapped . A secondary layer showing the extent of other pools that were investigated is also available. The purpose of this digitisation was to provide one collated layer showing the extent and distribution of saline lagoons in Wales. This layer may also be used as the basis for monitoring the extent of saline lagoons and therefore as a contribution to an assessment of their conservation status and to provide one collated layer showing the extent and distribution of saline lagoons in Wales. This layer may also be used as the basis for monitoring the extent of saline lagoons and therefore as a contribution to an assessment of their conservation status. This layer was created in January 2009 based on information provided by CCW Contract Science Report No. 464 (see related titles)."
