British Bryological Society

Description

Bryophyte records submitted to the Biological Records Centre for England, Ireland, Scotland, Wales, the Isle of Man and the Channel Islands. The dataset comprises records collected for the Bryophyte Recording Scheme, as well as those extracted from literature and museum sources. Details of all the surveys in this dataset can be obtained by clicking the 'Surveys' tab. This 'post-Atlas' dataset contains records received by the BBS after the production of the 2014 Atlas (Blockeel et al. 2014); it also contains any records that have been redetermined since inclusion in the 2014 Atlas (with the original records removed from the Atlas dataset GA000144). This new dataset currently contains records covering 139 vice-counties, with over five hundred records for each of the following (in descending order of abundance): Glamorgan, Cheshire, South Northumberland, East Sussex, West Sussex, Derbyshire, Merionethshire, Carmarthenshire, North Somerset, Renfrewshire, Shropshire (Salop), Cambridgeshire, East Norfolk, West Norfolk, East Suffolk, Anglesey, West Suffolk, Mid-west Yorkshire, Huntingdonshire, Buckinghamshire, Surrey, North-east Galway, Mid Perthshire, Breconshire, Outer Hebrides, South Hampshire, Caernarvonshire, South Devon, Argyll Main, East Cornwall, Nottinghamshire, South-west Yorkshire, Dumfriesshire, Northamptonshire, Offaly, West Inverness-shire, West Cornwall (with Scilly), South Wiltshire, Westmorland with North Lancashire, North Wiltshire, North Devon, Louth, Durham, South Lancashire, East Inverness-shire (with Nairn), North-west Yorkshire, Peeblesshire, West Galway, North Northumberland (Cheviot), and Cumberland.

Geographic Description

Great Britain, Ireland, Isle of Man, Channel Islands

Purpose

For county floras, national atlas production and inclusion in BRC database

Data quality

The data were validated against known vice-county distributions of the species, and (for critical species) by expert examination of specimens. Unusual occurrences were also flagged up to recorders on compilation of the data.

Methods

Almost all data were captured electronically by the recorders themselves. See the Atlas of Bryophytes (2014), vol. 1, pp. 2-11 for more historical detail.

Information withheld

Whilst this dataset is available at its full resolution as it is held on the NBN, the spatial resolution of the records of a small number of 'sensitive' species was coarsened on the creation of this NBN dataset. This applies to occurrences of Paludella squarrosa, Leiocolea rutheana and Meesia triquetra in Ireland.
