As the land slopes downwards you can see that it gets wetter, with rushes and irises becoming common amongst the grasses. In fact, to the north of here lies a turlough, a seasonal lake that dries in the summer but fills in the wetter months. Turloughs, from the Irish “tur-lach” meaning dry place, are a relatively uncommon geological feature, occurring almost exclusively in the Irish limestone landscape, with some being found in other parts of the British Isles. They are usually associated with a strange mixture of vegetation that is adapted to temporarily drying/wetting and can be important locations for overwintering migratory water birds, like white-fronted geese and whooper swans.
