Lough Derg and a section of River Derg, and the tidal stretch of the Foyle north of Lifford to the border, are also part of the site. The underlying geology is Dalradian Schists and Gneiss for the most part though quartzites and Carboniferous Limestones are present in the vicinity of Castlefinn. The hills around Lough Finn are also on quartzite. The mountains of Owendoo and Cloghervaddy are of granite felsite and other intrusive rocks rich in silica. The rivers in the western, upland part of the site flow mainly through peat based soils, while eastwards of the Ballybofey area the main Finn channel passes though fairly intensive agricultural land. In addition to rivers, lakes, bog and heath, the site includes native broad-leaved and mixed woodland, scrub, wet grassland and freshwater marsh. Intertidal mudflats and extensive reedbeds occur along the River Foyle. Improved grassland and arable land are included for water quality reasons. The Finn passes through a number of medium sized towns, notably Lifford, Castlefinn, Stranolar and Ballybofey. 4.2. QUALITY AND IMPORTANCE: This extensive site contains good examples of the Annex 1 habitats lowland oligotrophic lakes, blanket bog, transition mires and wet heath. Water quality of the lakes is good, as is that in most of the rivers and streams (majority classified as unpolluted). The blanket bog, which is best developed in the Owendoo/Cloghervaddy area, is typical upland bog and is fairly extensive in area. The Finn is an important system for Salmo salar, being an excellent grilse river with extensive spawning habitats. The Finn system sustains one of the only stable spring salmon populations in the country. The rivers and lakes support important populations of Lutra lutra. The upland habitats support a number of important bird species, notably Falco peregrinus and Falco columbarius (Annex I species) and Lagopus lagopus and Turdus torquatus (both Red Data Book species). Lough Derg supports the largest colony of Larus fuscus in Ireland. The section of the River Foyle within the site, along with a contiguous stretch in of the river in Northern Ireland, supports important populations of waterfowl 9 Site code: IE0002301 NATURA 2000 Data Form in autumn and winter, with an internationally important population of Cygnus cygnus, and nationally important numbers of Anser anser, Anas crecca and Phalacrocorax carbo. Salvelinus alpinus occurs in Lough Finn and possibly Lough Derg. A Red Data Book plant species, Cephalanthera longifolia, is known from the site. 4.3. VULNERABILITY While water quality throughout much of the site is good, there are some locally polluted stretches of river within the lowlands. Pollution, emanating from agricultural activities and centres of population, is a threat to the important Salmo salar populations. Afforestation already exists in part of the Finn catchment and poses a threat to water quality and fish stocks due to acidification and sedimentition. Further afforestation in the catchment could be damaging. The blanket bog and heath habitats are vulnerable to erosion due to over-grazing by sheep. Any further drainage within peatlands would be very damaging. 4.4. SITE DESIGNATION: 4.5. OWNERSHIP State : Department of Communications, Marine and Natural Resources Private : multiple 4.6.
