of land in Boho are managed under the Environmentally Sensitive Area (ESA) scheme, with more (ecologically) significant areas being designated as Areas of Special Scientific Interest (ASSI) or as Special Areas of Conservation (SAC). Farmers receive ESA payments for low-intensity farming, i.e. cutting a meadow after the grass and wild herbs have seeded (ESA scheme). Livestock (cows) were traditionally fed hay in the winter months as far up as the early 1980s, but modern methods of silage has overtaken this practice due to its higher nutritional value. Geological and hydrological environment There are also three mountain peaks in Boho, namely Belmore , Tullybrack, (incorporating Glenkeel, and Knockmore, . The area of Boho is replete with karst features such as potholes, limestone pavement, dry valleys due to the predominant limestone bedrock which gives it significance at a national level. The specific types of bedrock take their names from local townlands such as Carn Limestone, Knockmore Limestone and Knockmore Sandstone. Karst features There are three principal cave/karst systems in the Boho area, namely the Boho Caves, Reyfad–Glenkeel and Noon's Hole–Arch Cave system, situated under the mountains of Belmore, Tullybrack and Knockmore respectively. Many of these caves were first explored by local people, but the first detailed exploration and surveying of any caves in the area was undertaken by two cavers known as Édouard-Alfred Martel (the father of French speleology) and naturalist Lyster Jameson in 1895. Amongst the most notable caves beneath Belmore are Boho Caves, Aghnaglack Cave, Aghnaglack Rising, Pollbeg, Pollkeeran and Pollnagollum Coolarkan. Within the Tullybrack area are Braad Dry Valley, Carrickbeg (Bunty Pot), Fairy Cave, Ivy Hole, Little Reyfad, Mad Pot, Murphy's Hole, Oweyglass Caves, Pollbeg, Pollmore, Pollnacrom, Polltullybrack, Rattle Hole, Reyfad Pot and Seltanacool Sinks. The most notable caves in the Knockmore region include Noon's Hole, Arch Cave, Aughakeeran Pot, Crunthelagh Sink, Killydrum Sink, Old Barr Sink, Pollanaffrin and Seltanahunny Sink. Rivers and Loughs Rivers passing through Boho include the Sillees River which runs from Lough Navar Forest Park to Lower Lough Erne and its tributaries, the Screenagh and Boho Rivers. There are also five major streams which drain into the Reyfad/Carrickbeg catchment area and are linked to the Carrickbeg resurgence. One of these streams, entering Polltullybrack (second entrance to Reyfad Pot), is known as the Reyfad stream. There are four loughs associated with the civil parish of Botha, including Lough Nacloyduff () which is in the townland of
