In west Fermanagh, the Sillees Valley is a distinct and well defined lowland area. It is separated from Lough Erne by a ridge of limestone which rises to 200m at Cullen Hill and is bound to the west by the dramatic cliffs of the Knockmore Scarpland. The lowlands are choked with steep-sided drumlins which rise higher and are packed tighter towards the north-west. The Sillees River winds around between the hills through Carran and Ross Loughs to Upper Lough Erne.
The drainage pattern is intricate. The striking pattern of the drumlin hills creates a strong sense of enclosure which is emphasised by the small fields, tall hedges and abundant trees; gaps between drumlins reveal views over flat wet areas to hills beyond.
Forest plantations and woods are dispersed across the area adding variety to the landscape pattern. Small plantations fit well into the landscape, especially when incorporated within existing hedges.
There are a few large villages including Monea, where there is an impressive castle and Derrygonnelly, the largest local service centre. Elsewhere, settlement is dispersed along winding roads and occupies the higher ground of the drumlin tops and sides. Traditional single storey houses are often associated with groups of farm buildings.
Landscape Condition and Sensitivity to ChangeThe landscape is generally in good condition. The rolling patchwork of bushy hedgerows and hedgerow trees provides a robust framework which may accommodate changes in land use and some scattered new development.
Poor drainage impedes agriculture and in some places farm units remain subdivided into minute rush infested fields. Elsewhere, improved drainage has led to the development of larger fields and good grassland, although seasonal flooding has allowed the retention of flowery hay meadows beside the river.
There is much evidence of the dereliction of older properties and their replacement with new developments along roadsides, particularly on the fringes of Derrygonnelly.
