This is an area of low lying land that is criss crossed with drainage ditches called 'reens' in Wales. It is one of the largest surviving areas of ancient grazing marshes and reen systems in Britain, the Gwent Levels is of national significance for its wildlife, the area I have photographed is within one of several linked SSSI's (Site of Special Scientific Interest) at St Brides. There are currently plans to build an M4 relief road that would cut across the levels causing much disruption to the wildlife, not least to the Cranes that have started nesting here for the first time in 400 years.
