Eroding blanket bog<br />
This habitat occurs on blanket bogs (upland and<br />
lowland) where part of the original peat mass has<br />
been lost through erosion, and where sizeable<br />
areas of bare peat are exposed. Eroding blanket<br />
bog is most commonly associated with upland<br />
areas, and mountain peaks and ridges in particular.<br />
The causes of erosion are numerous; some erosion<br />
may have occurred as a natural process but, over<br />
the last two decades, overgrazing by livestock<br />
(particularly sheep) has been a major contributory<br />
factor.<br />
Eroding blanket bog is often characterised by<br />
networks of channels and gullies that have cut<br />
down through the protective layer of vegetation to<br />
expose the underlying peat. As erosion continues,<br />
these channels widen, deepen and coalesce until<br />
eventually the rocky substratum is reached. Some<br />
small blocks of the original bog, known as peat<br />
haggs, may remain.<br />
To be categorised as eroding blanket bog, a<br />
substantial proportion of the original bog surface<br />
should be missing and peat should have eroded<br />
below the rooting zone of the surface vegetation.<br />
In such situations, the process is likely to be<br />
irreversible, or recovery very slow, even if<br />
damaging activities cease. Eroding blanket bog also<br />
occurs on peatlands damaged by bog bursts when<br />
sizeable areas of bare peat are exposed.<br />
In <strong>Clare</strong> this habitat is recorded from Maghera<br />
Mountain Bogs NHA.<br />
