M10 Carex dioica – Pinguicula vulgaris mire <strong>and</strong> M11 Carex viridula subsp. oedocarpa<br />
– Saxifrage aizoides mire<br />
Most calcareous <strong>flushes</strong> in the hills belong to these two communities <strong>and</strong> the two can be<br />
difficult to separate. Both can occur as open, stony <strong>flushes</strong> but M10 generally has a more<br />
prominent vascular plant cover. The bryophytes are <strong>of</strong>ten the same in both communities;<br />
most consistent in the open stony areas are common species like Scorpidium scorpioides,<br />
Drepanocladus revolvens, Blindia acuta, Aneura pinguis (below bottom right), Campylium<br />
stellatum var stellatum, Ctenidium molluscum <strong>and</strong> occasionally Pseudocalliergon trifarium<br />
(below bottom left). The hummocks <strong>and</strong> margins <strong>of</strong> the <strong>flushes</strong> <strong>of</strong>ten have a greater diversity<br />
<strong>of</strong> species including rare <strong>and</strong> scarce species including Meesia uliginosa (top right) . The<br />
BAP species Tayloria lingulata is restricted to these two flush communities <strong>and</strong> M12, usually<br />
on hummocks within the flush. Another BAP species, Splachnum vasculosum, can form long<br />
st<strong>and</strong>s along the margins <strong>of</strong> the flush.<br />
M12 Carex saxatilis mire<br />
This uncommon flush type usually has a more complete <strong>and</strong> taller cover than M10 <strong>and</strong> M11<br />
with Carex saxatilis dominant but usually with other sedges. It is <strong>of</strong>ten not as strongly<br />
calcareous as the most diverse M10 <strong>and</strong> M11 <strong>flushes</strong> <strong>and</strong> is usually above 600m. The<br />
bryophytes are similar to M10 <strong>and</strong> M11 but <strong>of</strong>ten less diverse but a number <strong>of</strong> rarities do<br />
occur here including Tayloria lingulata.<br />
