Purpose

The purpose of this Coded List is to help those researchers wanting to collect and store information on freshwater and terrestrial algae in the British Isles, by providing a standard set of names and identifying codes. It includes the great majority of known records, though the authors are aware that several groups are not quite complete. It is hoped that the Coded List will stimulate many new surveys and that these will lead in turn to the recognition of many more taxa. Assembly of the Coded List is also an important step in the production of the 'Freshwater Algal Flora of Britain and Ireland', which was published in 2000.

The ‘Coded List of Freshwater Algae of the British Isles’ is based on, and much expanded from, the 1978 publication 'A Coded List of 1000 Freshwater Algae of the British Isles' (Whitton, Holmes & Sinclair) prepared for the then Water Data Unit of the Department of the Environment.

Format

Digital copy

The Coded List exists as a downloadable file which includes many diatom taxa found elsewhere in Europe, but not reported for the British Isles. These further diatom taxa have been taken from Krammer and Lange-Bertalot (1986 - 1991). The list makes clear whether or not they are species of the British Isles.

Truly marine blue-green algae are included in the Coded List, as floristic accounts of this group often combine freshwater and marine environments, and there are relatively few species in the British Isles restricted to the sea.
