For a Detailed Description of Sites of Local Nature Conservation Importance (SLNCIs) –see Plan Policy CON 1
Cut-over bog with fen and pools. Notable for aquatic invertebrates including the Irish damselfly.
Extensive areas of diverse bog vegetation.
Flood meadows adjacent to the River Blackwater, which are valuable feeding grounds for Greenland white fronted geese. The wet grassland is used each year by a flock of up to 100 geese and, additionally, waders and wintering wildfowl.
Ashfield Mountain Bar
The exposure of the Meenymore Formation at this site provides an excellent example of the variability that is typical of this Formation throughout the north of Ireland. Ranges of environments are exhibited, and diagnostic fossils collected here support the age ascribed to the formation as a whole.
Diverse swamp and fen with a number of notable species. The lake is a notable feature in the scenic landscape setting of Augher castle.
Eutrophic lake (lake type 12) with an abundance of the locally rare Ceratophyllum dermersum (Hornwort).
The Milltown section of this Blackwater river site is of importance as the type section for the Triassic Milltown Conglomerate Formation and the Derrycreevy Sandstone Formation. The range of sedimentary structures are among the best in Northern Ireland. The Benburb section of the river supports a Lower Carboniferous sequence, which provides one of the most complete and highly fossiliferous successions of strata in south County Tyrone and County Armagh. It is divided into four formations and constituent Members, all of which have type sections at this site. Similarities between strata exposed here and in Fermanagh allow possible correlations to be inferred and permit environmental reconstructions over a wide area.
Black Lough (Cormullagh)
The Lough is surrounded by species rich swamps and fen of local importance.
Eutrophic lake (lake type 15) with a rich aquatic flora including Ranunculus circinatus.
Caledon Estate Lough
Best example of lake type 12 within Tyrone, rich in aquatic flora.
Devonian rocks are of limited outcrop in Northern Ireland and volcanic rocks of Middle-Upper Devonian age are uncommon in Ireland. Those exposed in Cappagh quarry are the only Devonian lavas whose age is known accurately. The best exposure of lavas of the Barrack Hill Member is found in the working quarry.
One of the best examples of lake type 15 - Numphar (Yellow Water-lily) - Elodea (Canadian Pondweed), Chara-algae (Stonewort), within Tyrone. This low altitude lake generally has unenriched water chemistry.
Variety of fen and swamp associated with the lake.
The site gives very good exposures of sandstones of the Carrickaness Sandstone Formation. The site includes abundant fossils, including the rare occurrence of large specimens of solitary corals. The fossil assemblage is evidence for the proximity of a marine environment throughout the deposition of much of the sandstone.
Coalisland Brick Pit
The exposures of the Coalisland Brick Pit are the only known examples of ‘Coal Measure’ strata of Westphalin age that occur at the surface in Northern Ireland. The area has been famous for these seams since the 17th Century and the site has therefore an historical and social importance as well as being of geological significance.
Coalisland Sand Pit
Disused sand pit east of Coalisland. Regenerating scrub and diverse herb layer with two areas of open water. Some 24 sandmartin nest sites in south east corner of sand pit.
Cole Bridge Stream
The oldest beds of the Carboniferous sequence in County Fermanagh are only exposed north east of Enniskillen and on the north side of the Clogher Valley. The Cole Bridge stream section is probably one of the most complete through the Lower Carboniferous basal strata on the north side of the Clogher Valley. The section is the type locality for both the Ballyness and Clogher Valley formations. A variety of fossils obtained from the latter formation confirm its early age.
High variety of swamp, fen and wet grassland communities associated with the lake, including the notable Carex elata (Tufted Sedge) fen type.
Crilly House Quarry
The considerable depth of exposure at this site offers a variety of rock types that in some respects are typical of the Carrickaness Sandstone Formation but also show some variation from the norm.
Base-rich fen with a wide range of semi-natural wetland flora and fauna. Species include Carex nigra (Common Sedge), carex diandra (Lesser Tussock-sedge), Menyanthes trifoliata (Bogbean), Mentha aquatica (Water Mint) and Hydrocotyle vulgaris (Marsh Pennywort).
Extensive cut-over bog with a variety of swamp and semi-natural woodland communities.
Extensive areas of diverse wetland communities.
Drummond Quarry is a unique locality in Northern Ireland. It is only known quarry that is excavated solely in the Bundoran Shale formation and yields a fossil fauna that is diagnostic of age and is typical of the formation.
Landforms of the Edenfore area are a component of the Pomeroy Complex, a series of glacio-fluvial landforms along the watershed between the Omagh and Lough Neagh basins. Deposits at Edenfore consist of a flat-topped, dissected, steep-sided delta and deeply dissected outwash.
Mesotrophic Lake (lake type 8) with a rich aquatic flora including 5 pondweed species.
Fallaghearn was notable as a near-pristine complex of sand and gravel deltas dating from the end of the last Ice Age. Stepped delta surfaces showed the history of falling water levels within the impounded lake, which once occupied much of the Fintona uplands.
Fallow deer and mixed heronry in mixed woodland and open grassland. Under the terms of Wildlife (NI) Order a closed shooting season, for deer and heron nests must be protected at all times.
Landforms along the flanks of the Glenamuck/Blackwater River Valley are of importance in understanding the recent glacial history of Northern Ireland. The landform assemblage along the eastern assemblage of this valley consists of moraine and esker ridges and well-defined glacial terraces.
Eutrophic lake (lake type 16) with a rich aquatic flora including Potomogeton lucens.
The Fury is a small meandering River, which runs over carboniferous limestone. It rises in the Fardross Forest and joins the River Blackwater near Clogher. The river runs partly through coniferous plantation but downstream, has banks lined with seminatural woodland, purple moor grass and rush pasture. In this downstream section, the river is fast flowing and the channel substrate is composed of boulder and cobble. Notable evidence of otters, crayfish and active dippers.
Semi-natural Oak woodland of notable scientific interest.
Valuable breeding grounds for waders, in particular Snipe and Moorhen.
Mostly covered by reed swamp and fen vegetation, this substantial site is surrounded by not too intensively managed farmland. Significant local interest.
Diverse swamp/fen with a number of notable species of high conservation concern.
Eutrophic lake (lake type 16) with a rich aquatic flora, including Potamogeton praelongus.
Mesotrophic lake with a rich and diverse aquatic flora.
Lough nablaney bane
Mesotrophic lake (lake type 8) with a rich aquatic flora with 5 pondweeds including Potamogeon praelongus and gramineus. The margins support a well developed swamp and fen fringe.
Sited south of Ballysaggart Lough, this site is open fen of local interest.
Mesotrophic lake (lake type 9) with rich aquatic flora including Ranunculus circinatus.
Variety of fen and swamp communities present, including alkaline fen. Both the lake and the fen habitat are of high nature conservation value.
Plaister Quarry exposes a small thickness of limestones and shales that are typical of the upper part of the Maydown Limestone Formation and contains a prolific fossil fauna dominated by corals and brachiopods of early Asbian age.
Wet grasslands frequented by feeding waders. Local fen interest.
Although this woodland seems to be derived from a 200-250 year old plantation, it is in a comparatively natural state with mainly Ash, Birch, Oak and Hazel. Good ground flora, structure, etc. with several notable higher plants present. The woodland is of high conservation value.
Roughan Lough (part of)
Eutrophic lake (lake type 16) with a rich aquatic flora with 5 pondweed species including Potamogeton lucens, gramineus and filiformis.
The water chemistry of the lake is relatively unenriched. There is a variety of some of the best associated swamp and fen. Best example of a lake type 14 - Nuphar (Yellow Water-lily), Elodea (Canadian Pondweed), Potamogenton alpinus (Red Pondweed), within Tyrone.
Cut over bog with wet heath and species-rich acid fen around edges. Notable as a Marsh Fritillary Butterfly site.
This isolated outcrop of the Ballyshannon Limestone Formation is the most easterly recorded in Northern Ireland and therefore provides an indication of the extent of the depositional environment of this formation.
The Tircar stream section exposes the probable base of the Alderwood Mudstone Member. This section is considered to contain most lithologies that are typical of this Member, which is confined to a very small area of County Tyrone.
Torrent River (part of)
The Torrent is a long meandering river, which drains the hills to the north-west of Dungannon. The underlying geology is varied and includes basal clastic, carboniferous limestone, coal and Old Red Sandstone. In the upper reaches, the river channel is shallow and narrow with pebble/cobble substrate and sandy banks. Downstream the banks are vegetated with tall grasses and native tree species. Fishing weirs add to interest. In its lower reaches, the Torrent widens and runs parallel to the Coalisland Canal.
Species-rich neutral grassland with frog orchid and an abundance of greater butterfly orchid.
Eutrophic lake (lake type 12) with a rich aquatic flora including 5 pondweed species and Ranunculus circinatus
