Stoneworts in Wales

Natural Resources Wales

Description

A collation of all known records of stoneworts in Wales from 1726 to August 2003. Stoneworts (or charophytes) are a group of algae that grow in fresh and brackish water and have a relatively complex structure.

Geographic Description

All Wales

Purpose

Stoneworts are good indicators of water quality as they are sensitive to pollution, including nutrient enrichment. Many are of conservation importance. 30 species have been recorded in the UK and 17 of these occur in Wales. Of the latter, 4 are Red Data Book species, 6 are Nationally Scarce, and 9 are considered rare in Wales; 3 are Priority Species in the UK 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).

Methods

For each record in the collation the collector or recorder is named and in most cases there is a reference to the original source. The collation has been updated in 2008. The data has been derived from a range of sources; mostly from articles in journals, floras and guides, but also from herbarium records, personal observations and commissioned surveys.
