Gwent Levels / Severn Estuary
A land of mistletoe, marshes and reens, or ancient drainage ditches, the Gwent Levels are a rich area of intertidal mudflats and alluvial wetland on the northern side of the Severn Estuary.
A completely man-made landscape from the Roman period onwards, it provides a wide range of rich wildlife habitats and farmland. Although close to the M4 motorway, it sometimes seems as if the Gwent Levels has a different pace of life.
The northern banks of the Severn give way to the two tiny sentries of Steep Holm and Flat Holm Islands standing guard in the Bristol Channel.
North, we can trace the wooded valleys of the river Wye flowing down past Tintern Abbey to meet the Severn. West, we come to the hills and forests above the south Wales valleys, with large areas of water such as the Wentwood and Llandegfedd reservoirs. Llandegfedd is considered the most important freshwater site for birds in south east Wales.
