Breen Wood SAC

Breen Wood SAC extends for just over one and a half kilometres along the lower northern slopes of Bohilbreaga and includes all the Oak woodland and an area of adjacent wet heath located above the western third of the wood.  The terrain in the western half of the site is relatively uniform with the wet heath covering a low gradient slope merging into a steeper wooded ridge slope below, which descends down to the flat valley floor.  The terrain on which woodland occurs in the eastern half is by contrast extremely undulating as the area is traversed by a series of glacial outflow channels which has created a series of dry low ridges interspersed by damp, narrow valleys.  Where these valley floor has become waterlogged small pockets of Bog Woodland have developed.
