Cors Bodeilio National Nature Reserve

Overview

Cors Bodeilio NNR on Anglesey is nationally important due to its unique mire, which lies in a shallow limestone valley between Llangefni and Pentraeth. Water from the surrounding Carboniferous limestone feeds the mire, and this has encouraged the development of a range of different wetland fen species, which grow on a bed of fen peat and encourage a range of other wildlife. The main habitat of the lime-rich fen is characterised by specialist species such as great fen and bottle brush sedge. In some areas the fen is fed by springs and flushes where other rare plants, such as black bog rush, sweet gale and small flowered rush, thrive. In spring and summer the reserve rings with the calls of feeding birds such as breeding warblers, curlews, breeding lapwings and snipe. The reserve is one of only two sites on Anglesey where breeding snipe are found.

About the area

Some of the oldest rocks in Britain form the 125-mile coastline of the 85 square mile Anglesey Area of Outstanding Natural Beauty, which includes Holy Island with its busy port of Holyhead, the terminus for the Dublin ferry. The terrain inland is mainly a fertile plateau worn flat by the action of the sea, with low ridges and shallow valleys, while the sheer limestone cliffs of the east coast and on the north coast at Holyhead Mountain represent some of the most spectacular sea cliffs in Britain.
