Rhestr Data Coch Bryoffytau ar gyfer Cymru
A Bryophyte
Red Data List
for Wales
Following the publication of A Vascular Plant Red Data List
for Wales (Dines, 2008), Plant Link Cymru is promoting the
production of similar Red Data Lists for other groups of
plants in Wales where possible, especially where this will
improve our knowledge of the threats facing these species
and the availability of data.
This report is the first to assign threat categories to Welsh
mosses, liverworts and hornworts (bryophytes), and the first to
use IUCN categories at a regional scale for this taxon group in
Great Britain. Wales has a particularly rich bryophyte flora, with a
greater proportion of Britain’s species occurring within its
borders than is the case for vascular plants, and a far greater
number reaching the limits of their range within the country.
Some bryophytes have been found to be more threatened in
Wales than in Britain as a whole, whilst others appear to be
holding their own more effectively in Wales than in England or
Scotland. Wales has a responsibility to protect and conserve all of
these threatened species, and the list of bryophytes that appear
on the next revision of Section 42 of the Natural Environmental
and Rural Communities Act (NERC) 2006 (Habitats and species
of principal importance in Wales) should be informed by the
findings of this study.
This report has been produced by Plantlife Cymru with the
support of the Countryside Council for Wales and the British
Bryological Society.
