About Lough Oughter Complex Special Area of Conservation

 

The Lough Oughter Complex Special Area of Conservation (SAC) is an ecologically significant wetland system located in the north of County Cavan, Ireland. Formed by interconnected lakes, rivers, water channels, islands, peatlands, and woodlands, it is one of the most important freshwater wetland ecosystems in the country. The complex includes Lough Oughter itself along with its surrounding lakes such as Lough Ruddan and Lough Bannow. Geographically, the area sits within the Erne river system and showcases a unique landscape of low-lying limestone plains interspersed with rich habitats. Ecologically, the SAC supports a diverse range of species, including rare wetland plants, otters, freshwater pearl mussels, and an internationally important population of overwintering waterfowl. The habitat diversity encompasses wet meadows, reed beds, alkaline fens, and old oak woodlands. Historically, the region is dotted with medieval monastic settlements and castle ruins on some of the islands, adding an element of cultural interest to the natural setting. Outdoor enthusiasts are attracted to the Lough Oughter Complex for its excellent fishing opportunities, mainly pike and coarse fishing, alongside canoeing, kayaking, and birdwatching, with numerous vantage points for spotting migratory wildfowl and raptors. The tranquil waterways invite paddlers to explore the maze of islands and channels, while walking routes nearby provide a chance to experience the rich flora and fauna. The complex’s blend of natural beauty, wildlife, and heritage offers a tranquil and enriching visitor experience, appealing especially to nature lovers, anglers, and photographers.
