New Census Catalogue Call for Records

A new Census Catalogue will be published in 2021 to replace the current 2008 edition and later interim versions. In the new CC, the bracketing date will be moved from 1960 to 1970, meaning that any taxon not recorded in a vice-county in the last 50 years will be bracketed. It will also adopt the names and taxonomic concepts to be published in the forthcoming British and Irish Checklist.

If you are a Regional Recorder, it is important that you submit any outstanding records to the Recording Secretary, Oli Pescott ( by the end of January 2021. If you are a member, please send your records to your Regional Recorder by the end of 2020. In either case, recorders submitting older records are encouraged to check potentially ambiguous names in their dataset before submission (e.g. are all records named Ulota crispa referring to the same taxon? Do your older records of Sphagnum fuscum need to be explicitly labelled as sensu lato? Etc.) New vice-county records and debracketings should continue to be sent to the Recorders for Liverworts and Mosses via the normal voucher system.

  • ** New ** Save the date! The Plas Caerdeon meeting originally scheduled for Spring 2020 has been rearranged for 13-17th September 2021. More details will follow in due course.

  • The Autumn Liverwort workshop has been postponed due to Covid-19 concerns. Please read the full announcement on the Local meetings page.

  • For those of you who were looking forward to coming to the summer meeting on Jura this year, some cheery news: we are hoping to reschedule the event for June 2021, (Saturday the 19th to Saturday the 26th), and the village hall has been booked for evening microscope work again for that week, (pending the easing of travel restrictions etc of course).

  • Phil Stanley’s latest version of the BBS Cumulative Index, version 16.1 has been uploaded (dated 17 February 2020) and is avaiable at
    It now includes citations from Journal of Bryology volume 41, Part 4 (2019) and up to Field Bryology 122 (2019) and also a list of all the references quoted in papers (Allrefs) published in Journal of Bryology and Field Bryology.

You will need to create an online account (free), then click on the New content alerts button on the main JoB page and follow the instructions. If you have any problems with this, please contact T&F, not the BBS.



New Atlas of British and Irish Bryophytes

A reminder to all bryophyte lovers that the Atlas of British and Irish Bryophytes is available for sale from this link.

This flagship publication of the BBS not only holds the most up-to-date set of distribution maps for all British and Irish bryophytes but also a wealth of information about each species’ ecology, altitudinal range, associated species and world-wide distribution.

A stupendous achievement by the authors as well as a tribute to the work of the BBS: it is difficult to know why anyone would not be anxious to secure a copy.

BBS Field Guide to the Mosses and Liverworts of Britain and Ireland

This book, produced by the BBS, is the only up-to-date, user-friendly guide to identifying British and Irish bryophytes in the field.  It contains hundreds of colour photographs and black and white drawings showing what species look like, together with notes on how to identify and distinguish similar species, and habitat notes and distribution maps showing where they occur.

An essential field companion for any serious bryologist.

Future Meetings

Would you like bryologists from all over Britain and Ireland to come and help you record your county or local area?

If the answer is yes, then you could host a BBS Spring or summer Meeting! Spring and Summer meetings are usually 5 -7 days long and all you need to do is find sites that need recording. A bunch of friendly bryologists will then come and record in the chosen locations and you can watch the record cards coming in... Meetings are also a great opportunity for beginners to learn from expert bryologists in the field.

If you think you could host a Spring or Summer meeting in 2022 or 2023, please get in touch with Lucia Ruffino at or on Twitter.
