Caldanagh Bog

A compact lowland raised bog within the River Main series displaying a classic domed profile with minimal turf cutting around the periphery. An area of intact lagg along the north-eastern edge of the bog represents one of the most important features of the site. The intact surface supports a moderately well developed hummock/hollow complex and the surface of the bog is exceptionally wet supporting a dense and diverse cover of Sphagnum mosses. Of particular note, the nationally rare Sphagnum pulchrum is abundant in the hollows and notable hummock-forming mosses. Some of the peripheral peats have been cut for turf in the past with vegetation communities ranging from deep artificial pools to Purple Moor Grass dominated grassland. The overall diversity of Caldanagh Bog is enhanced by a small esker ridge to the south-west, where the vegetation is dominated by a heath and grassland mosaic. The notable Burnet-saxifrage grows on this esker ridge.

Dunloy Bog

One of the largest remaining undamaged lowland raised bogs in NI. Important for its bog-to-lagg transition. The site has extensive Sphagnum cover and several notable plant species including burnet saxifrage and cowberry.

Frosses Bog

A compact, relatively undisturbed lowland raised bog representing the most southern example within the River Main series which includes the existing ASSIs Dunloy Bog and Caldanagh Bog. The intact bog surface exhibits a well defined dome profile with structural features including hummock and lawn complexes and small shallow pools. The bog supports a dense and diverse cover of Sphagnum bog -mosses including the nationally rare S. pulchrum in the wetter hollows and the notable hummock forming moss S. imbricatum. The abundance of Cranberry throughout the bog plain is notable and the presence of Crowberry on the intact dome is an unusual feature on a lowland raised bog. The lagg surrounding the bog has been cut for turf, creating a mosaic of habitats dependent on peat-depth and age of cutting. Vegetation communities range from acid pools choked with Sphagnum mosses through acid grassland to 'poor' fen and swamp.

Garry Bog

The intact surface displays a small pool complex with moderate hummock and hollow development supporting a number of rare species. The Garry Bog system is internationally significant for peat stratigraphy which displays a classic sucession from clay and lake muds , through reed swamp and wood peats to raised bog peats . Recently volcanic glass shards (tephra), have been identified in the peat column, permitting more reliable correlation of the peat stratigraphy .
