Croaghonagh North comprises 33 hectares of blanket bog located close to Lough Mourne in the Barnesmore Gap, approximately 8 kilometres southwest of Ballybofey, Co. Donegal. The site lies within the Croaghonagh Bog Special Area of conservation which supports some of the best examples of wet lowland blanket bog in the county. The site adjoins two good examples of oligotrophic lake habitat namely Lough Mourne and Lough Carn.
The project site consists of two portions of unplanted bog. The northern portion is larger and it comprises an intact northeastern half and a drained, but unplanted, southwestern half.
The vegetation of the intact portion is dominated by purple moor-grass (Molinia caerulea) with numerous wet pool areas and a high cover of Sphagnum mosses, including the uncommon species Sphagnum imbricatum and S. fuscum.
The primary restoration measure at this site involves the blocking of the drain network to the north of Lough Carn in order to raise the watertable and rehabiliate the blanket bog habitat. This network of drains was ploughed in the early 1990's however trees were not subsequently planted.
