Tonnagh Beg Bog ASSI is a large, relatively intact lowland raised bog which is among the best remaining examples in the west of Northern Ireland. Typical of western bogs, the site is rather irregular in shape. The intact bog surface exhibits a well defined dome with characteristic vegetation and structural features, including hummock and lawn complexes and small shallow pools.
Sphagnum species are well represented. Notably, the bog supports a very high frequency of the rare mosses, Sphagnum imbricatum and Sphagnum fuscum , which form well-developed hummocks over the wet surface. The lagg surrounding the intact bog has been cut for turf in the past, creating a mosaic of habitats ranging from acid grassland to small pockets of birch and willow scrub.
