Annex I habitats that are a primary reason for selection of this site
Breen Wood is one of the best examples of old sessile oak woods in Northern Ireland. It is traversed by glacial outflow channels that have formed a series of dry, low ridges interspersed by damp, narrow valleys. Over these freely-draining and leached slopes, the wood is strongly calcifugous in nature, with a high canopy of downy birch Betula pubescens and oak Quercus spp. The shrub layer is composed of rowan Sorbus aucuparia with some holly Ilex aquifolium. The field layer is dominated by bilberry Vaccinium myrtillus, with occasional bramble Rubus fruticosus agg., honeysuckle Lonicera periclymenum and ferns, typically bracken Pteridium aquilinum. The herb layer is overwhelmingly dominated by extensive carpets of great wood-rush Luzula sylvatica. The only other species that occur to any significant extent are hard fern Blechnum spicant and wood-sorrel Oxalis acetosella. Breen Wood is the only known location in Northern Ireland for the moss Hylocomium umbratum.
