Annex I habitats that are a primary reason for selection of this site

3150 Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation
Upper Lough Erne in Northern Ireland is a very large natural eutrophic lake situated in a drumlin landscape and has a predominantly limestone catchment. The site is an example of a northern or western eutrophic lake of glacial origin. The lake has a very long shoreline and numerous associated satellite lakes, many of which are included in the site. Aquatic vegetation of the Magnopotamion and Hydrocharition type is extensively-developed. Both club-rush common reed Scirpo Phragmitetum and reed canary-grass shoreweed spike-rush Phalaris Littorella Eleocharis associations are well-developed on the shore. There are transitions to swamp and fen vegetation.
91A0 Old sessile oak woods with Ilex and Blechnum in the British Isles
Upper Lough Erne represents one of the largest areas of semi-natural woodland remaining in Northern Ireland. Drier soils support mature stands of old sessile oak woods, which are particularly well-developed to the south of the lough. The woodlands consist of a canopy dominated by oak Quercus petraea, with occasional ash Fraxinus excelsior and birch Betula pubescens. Hazel Corylus avellana and holly Ilex aquifolium often form a distinct shrub layer. The ground flora is very variable and consists of a wide variety of species, including bluebell Hyacinthoides non-scripta, sanicle Sanicula europaea, goldilocks buttercup Ranunculus auricomus, great wood-rush Luzula sylvatica, and an abundance of the scarce thin-spiked wood-sedge Carex strigosa.
91E0 Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae)  * Priority feature
Upper Lough Erne is the most extensive area of alluvial forests in Northern Ireland. The woodland occurs in scattered stands around the edges of the lough, where the shoreline is ungrazed or only very lightly grazed. Fluctuating water levels and variations in exposure, substrate and management have resulted in the formation of a wide range of wet woodland communities. These are generally characterised by a canopy in which species such as willow Salix spp. and alder Alnus glutinosa are dominant, with more notable species such as aspen Populus tremula, guelder-rose Viburnum opulus and buckthorn Rhamnus cathartica scattered throughout. The ground flora is often similar to that of the swamp and fen zone, with a rich variety of sedges and herbs. In places, there are well-developed transitions to drier woodland types, including 91A0 old sessile oak woods with Ilex and Blechnum.

Annex II species that are a primary reason for selection of this site

1355 Otter  Lutra lutra
This site represents otter Lutra lutra in Northern Ireland. The province holds one of the strongest populations of otters in the UK. Upper Lough Erne consists of a large eutrophic lake with very extensive associated wetland habitats that holds a dense and large population of otters. In addition the surrounding countryside is rich in relatively unpolluted rivers and lakes and has a high density of semi-natural habitats, especially wetlands, supporting the otter population within the site.
