also often be found, which can promote an even greater diversity of species. Limestone grassland habitat in Northern Ireland is exclusive to County Fermanagh from the Boho–Knockmore region to Cuilcagh Mountain Park, this habitat and its associated karst features are so environmentally important that the latter Marble Arch region was designated part of the European Geoparks Network, the Global Network of National Geoparks and the world's first International Geopark, consequently adding international significance to the Boho landscape. In Boho, this type of land is often associated with dry stone walls, built from limestone, which are constructed in a peculiarly local style and are equally important source of biodiversity. There are large areas of bog in Boho, typified by species such as bell heather, cross-leaved heath and ling (common heather). Additionally species such as sundew (which are carnivorous) and bog asphodels can be found. The woodlands of Boho consist of a mixture of plantation woodlands and semi-natural broadleaf woodlands (mainly ash and hazel). As well as these rich ecological resources, Boho is well known for its small field sizes, which provide many field boundaries of hedges and dry stone walls. Scheduled species Added to the importance of the above habitats, the Boho area includes large numbers of rare and protected plant species specified as priority species by the Northern Ireland Environment Agency, including Irish eyebright (Euphrasia salisburgensis var. hibernica) which is located on the western edges of Boho near Knockmore cliffs, small white orchid (Pseudorchis albida), also known as the white mountain orchid, blue-eyed grass (Sisyrinchium bermudiana), which belongs to the American element of the Irish flora i.e. those plants being absent from any other part of Eurasia but exist in North America, green-flowered helleborine (Epipactis phyllanthes), Cornish heath (Erica vagans), which is found near Boho, yellow bird's-nest (Monotropa hypopitys),. Other notable species to be found in the area include Swedish pouchwort (Calypogeia suecica), a bryophyte last found in Aghahoorin near Boho in 1961, bee orchid, (Ophrys apifera), mountain avens (Dryas octopetala), marsh helleborine, (Epipactis palustris) and bird's-nest orchid (Neottia nidus-avis) located in proximity to Boho Caves. Microbiota Microbiota or microscopic organisms specifically associated with the Boho alkaline/radon environment include a bacterium known as Streptomyces sp. myrophorea, isolate McG1. This species of Streptomyces was isolated from an old local soil cure that dates back to the Reverend James McGirr, the Christian parish priest of Boho in 1803. In antibacterial tests, this
