Cranny Bogs SAC

Cranny Bogs is made up of three inter-drumlin, lowland raised bogs - Fallaghearn Bog, Killymoonan Bog and Cavan Bog.  They are typical of western bogs within the drumlin belt of Northern Ireland, being elongated and/or very irregular in shape.  Generally, dome structure is poorly defined.

The two eastern bogs are linked together around a small drumlin, the third lies to the south-west but in close proximity.  The bogs vary considerably in their microtopography, with Fallaghearn in particular displaying relatively well-developed hummock (including Sphagnum imbricatum and S. fuscum) and lawn complexes.  Hummocks on Killymoonan and Cavan Bogs are generally more subdued.  Shallow, temporary pools are scattered over the three bogs.
