Census Catalogues list – for each species or taxon – the Watsonian vice-counties in which it has been recorded, and are a useful tool for regular recorders. Full catalogues are produced every 10 years or so, but updates are periodically issued in the form of Interim Census Catalogues. All catalogues will be made available on this page, with the latest at the top.
Interim Census Catalogue 2023

A Census Catalogue of British and Irish Bryophytes 2021
by T.L. Blockeel, N.G. Hodgetts, S.L. Pilkington and O.L. Pescott
The last full catalogue was printed in 2008 (see below) and since then there have been numerous changes to the nomenclature and systematics of our bryophytes, in many cases prompted by molecular studies. Almost 40 mosses and liverworts have also been added to the British and Irish list in the intervening years.
Following the publication of a new bryophyte checklist for Britain and Ireland in 2021, this new edition of the Census Catalogue reflects current bryophyte nomenclature and incorporates the numerous updates to the known distribution of our bryophytes at a local level up to and including 2020. Please note that this initial version of the Census Catalogue does not include new records made during 2021.
The Census Catalogue is available to download here in PDF and spreadsheet format. The PDF is identical to the printed version. The spreadsheet version contains the data from the PDF/printed catalogues, but in a more searchable form. It will periodically be updated as new data becomes available.
For those who prefer a printed copy, it is available as an A5 softback book which can be ordered below.
Census Catalogue correction
Please note: in the new Census Catalogue, the entries for the former Telaranea murphyae, now considered a synonym of Tricholepidozia tetradactyla, were not transferred to the latter species. The entries for vice-counties 1, 9 and 11 are therefore missing under T. tetradactyla. They will be formally reinstated in the Liverwort Year report for 2021.

This interim Census Catalogue includes additions and amendments compiled 2008-2018, as well as records that had been submitted to the Biological Records Centre but had not been entered to the database in time to prevent their vice-county being signified as an old (pre-1960) record in the printed 2008 Census Catalogue. This version also includes the amendments resulting from preparation of the 2014 BBS Atlas.
Hill, M.O, Blackstock, T.H, Long, D.G & Rothero, G.P. 2008. Check-list and Census Catalogue of British and Irish bryophytes.
Publisher: British Bryological Society. Paperback, laminated covers. 184 pages.
Printer: Latimer Trend & Co. Ltd., Plymouth
The 2008 Census Catalogue presents a full revision of the classification, nomenclature and vice-county distribution of British and Irish bryophytes. In 304 genera it lists 1056 species (4 hornworts, 297 liverworts, 755 mosses), 7 subspecies and 88 varieties. Genera are arranged in families and orders according to recent global taxonomic arrangements by Crandall-Stotler, Stotler & Long (2008) for liverworts and Goffinet & Buck (2004) for mosses. Nomenclature generally follows the standard British floras of Paton (1999) and Smith (2004). All deviations from the nomenclature of these floras are fully annotated. The 68764 vice-county occurrences correspond to an average 62 records per listed taxon, of which 10% are old (i.e. pre-1960) records. All listed vice-county occurrences correspond to at least one localized record in the BBS database.
