Atlas of British and Irish Bryophytes

Members may be interested to know that the 2-volume Atlas of British and Irish Bryophytes, published in 2014, is now available at a reduced price of £50 plus p&p (full price £75 plus p&p) during the pre-Christmas period. This is an opportunity not to be missed if you do not already have a copy.

All 1069 species of hornworts, mosses and liverworts known from Britain and Ireland at the time of publication are mapped in colour. The Atlas incorporates the results of 20 years’ fieldwork by members of the British Bryological Society. The hectad (10 × 10 km square) maps reveal dramatic changes in the distribution of some species since 1990. Each map is accompanied by a detailed text covering habitat, reproductive biology, significant range changes, taxonomic or recording problems and world distribution. The altitudinal distribution of most species in Britain is illustrated by a novel diagram, and the species accounts are illustrated by numerous habitat photographs. 

The introductory chapters describe the history of the BBS recording scheme, highlighting the effect of technological changes since 1990, and map environmental factors relevant to the interpretation of the maps. An important chapter presents a new analysis of the records to identify changes in frequency in recent decades in response to drivers such as air pollution, land-use and climate change.

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 2019 or 2020, please get in touch with Lucia Ruffino at or on Twitter.
