Largalinny ASSI

Mature semi-natural woodland , typically calcifugous, with localised base-rich flushing along the gentler south-facing slopes and along the narrow valley of the Sillees River. The structure, plant community diversity and the rich flora collectively make Largalinny one of the most important woodlands in Northern Ireland.

It supports a number of rare plant species including notable bryophytes and lichens. The site displays a natural transition from woodland to heath.
Heathland on the gentler dip slopes support additional plant and animal communities, and two small waterbodies add further diversity to the site.
These rich and variable habitats give rise to notable populations of both dragonflies and moths.

The geological interest of the site is centred on the silicified fossil fauna from the Glencar Limestone Formations at Carrick Lough,which are of international importance.

The scarp and dip slope topography displayed by the Glenade Sandstones are of physiological interest and provide the underlying growing conditions for the diversity of plants and habitats throughout the site.
