Stoneworts (or charophytes) are a group of algae that grow in fresh and brackish water and have a relatively complex structure. Stoneworts are good indicators of water quality due to their sensitivities towards pollution, including nutrient enrichment acting as a bio-indicator. Many are of conservation importance. 30 species have been recorded in the UK and 17 of these occur in Wales. Of the latter, four are Red Data Book species, six are Nationally Scarce, and 9 are considered rare in Wales; three are Priority Species in the UK Biodiversity Action Plane (BAP) and are included on the National Assembly of Wales' List of Species and Habitats of Principal Importance for the Conservation of Biological Diversity (Section 74 list). All data collated and verified at source by known expert. A collation of all known records of stoneworts in Wales from 1726 up till August 2007.
