A Bryophyte Red Data List for Wales<br />
26<br />
7.6 Species for which Wales has a particular<br />
responsibility<br />
Consideration is given here to those taxa for which Wales has a particular responsibility<br />
for conservation. In the GB Red Data List (Hodgetts, unpublished), taxa for which Great<br />
Britain has an international responsibility are indicated by showing those for which we<br />
probably or definitely have more than 25% of the European population.<br />
For <strong>this</strong> study a very crude assessment of responsibility has been made using the number<br />
of hectads occupied by each taxon in Great Britain. This total was compared with the<br />
number of extant (post-1970) Welsh hectads. Any taxon for which Wales has 25% or more<br />
of the GB population is indicated in the Red Data List. In order to highlight conservation<br />
priorities, all of these taxa that are also threatened in Wales are listed in Table 8. In<br />
addition, the list includes 10 taxa that are of Least Concern in Wales but for which Wales<br />
holds 50% or more of the GB population. Several of these are considered Threatened or<br />
Near Threatened in GB as a whole.
