Valley Wetlands

The eastern part includes Llyn Traffwll and wetlands along the Afon Crigyll.

Outside the breeding season, duck numbers increase and bittern and marsh harrier are regularly seen.

Several rare birds have been recorded such as whiskered tern, green-winged teal and ring-necked duck.

The reserve is rich in wetland plants with large areas of reed and willow and uncommon species such as eight-stamened waterwort, flowering rush, marsh fern and hop sedge.

Among the insects are hairy dragonfly, variable damselfly and various water beetles.
