Tonnagh Beg Bog

Tonnagh Beg Bog is among the best remaining examples of a lowland raised bog in the west of Northern Ireland. Typical of western bogs, the site is rather irregular in shape, with deep peat encircling a small drumlin of grassland on mineral soil. The uncut surface has a well-developed microtopography, consisting of a pool complex interspersed by well-formed hummocks, wet lawns and a soakway. Despite some burning in the past, the surface has an extremely high Sphagnum moss cover and a notable Sphagnum moss hummock development.

Cranberry is locally frequent, growing over the surface of the highest hummocks.

There is no public access to this site.
