Description

Knockninny Hill Higher plant assemblage, Invertebrate assemblage Calcareous grassland, Mixed ashwoods The area is of special scientific interest because of its limestone Karst features and flora and fauna. Karst features consist of localised exposures of limestone pavement. Biological interest is related to the quality and diversity of the base-rich woodland and grassland, and the rich assemblage of invertebrates. Several rare species are present. Knockninny Hill is a residual block of hard limestone from the Lower Carboniferous Age and includes the summit plateau and steep flanks of the hill, in addition to lower ground to the east. Limestone pavement occurs on the swnmit and northern flanks of the hill. This is a Karst feature that is rare in the British Isles generally, and in Northern Ireland is confined to County Fermanagh. It was formed by the scouring action of the ice during the last Ice Age, some 10,000 years ago. Water action then widened the cracks in the limestone to form a complex pattern of crevices known as grikes, between which are massive blocks of worn limestone called glints. The summit and northern slopes support a rich, limestone grassland plant community. This is characterised by a short, grazed sward that includes such plants as blue moor grass Sesleria caerulea, glaucous sedge Carex flacca, mouse_ear hawkweed Pilosella officinarum, devils-bit scabious Succisa pratensis, ribwort plantain Plantago lanceolata, lady's bedstraw Galium verum, eyebright Euphrasia spp. and quaking grass Briza media. Common mosses include Ctenidium molluscum, Dicranum scoparium and Tortella tortuosa. In addition to its species-richmess, this grassland supports a number of notable plants including mountain everlasting Antennaria dioica and mossy saxifrage Saxifraga hypnoides, and a diverse orchid population with small-white orchid Pseudorchis albida, fragrant orchid Gymnadenia conopsea, frog orchid Coeloglossum viride and pyramidal orchid Anacamptis pyramidalis. Of particular note, dense flowered orchid Neotinea maculata is present in only its second known Northern Ireland location. The steep, rocky flanks of the hill are covered by well-developed woodland that is characteristic of shallow, limestone soils. The canopy is dominated by ash Fraxinus excelsior and hazel Corylus avellana. The ground flora is typically species-rich and contains such species as wood sorrel Oxalis acetosella, bluebell Hyacinthoides non-scripta, ivy Hedera helix, barren strawberry Potentilla sterilis, primrose Primula vulgaris, lords and ladies Arum maculatum, pignut Conopodium majus and water avens Geum rivale. Lower plants are also well-represented and include mosses such as Cirriphyllum piliferum, Eurhynchium striatum, Eurhynchium praelongum, Thamnobryum alopecurum and Plagiomnium undulaturn. The woodland supports a number of notable species such as Columbine Aquilegia vulgaris and stone bramble Rubus saxatilis, and includes the very rare yellow birds nest Hypopitys monotropa. A series of old meadows occurs on the deeper, heavier clay soils around the lower slopes of the hill. Flushing by base-rich water from the upper slopes has produced a species-rich sward. Grasses such as sweet vernal grass Anthoxanthum odoratum, meadow foxtail Alopecurus pratensis, crested dog's tail Cynosurus cristatus and Yorkshire fog Holcus lanatus are generally dominant. These are typically intermixed with sedges including glaucous sedge Carex flacca, wood sedge Carex sylvatica and oval sedge Carex leporina, and herbs such as common knapweed Centaurea nigra and lady's mantle Alchemilla glabra. Greater butterfly orchid Platanthera chlorantha occasionally occurs. Where flushing is more pronounced, sharp flowered rush Juncus acutiflorus becomes more frequent, in addition to sedges such as carnation sedge Carex panicea and flea sedge Carex pulicaris, and wetland herbs such as meadow sweet Filipendula ulmaria, tormentil Potentilla erecta and devils-bit scabious Succisa pratensis. The moss Calliergonell cuspidatum forms an underlying mat. Knockninny Hill is also important for Lepidoptera, butterflies and moths, with 15 species of butterflies believed to breed there. Grayling Hipparchia semele is of particular note, as this is the only known inland breeding site for this species. Other notable invertebrates include the millipede Brachyiulus pusillus and the woodlouse Armadillidium pulchellum, both of which are very locally distributed in Northern Ireland. https://www.daera-ni.gov.uk/publications/knockninny-hill-assi
