There's a south facing bank around the back of the Gilchrist Thomas Industrial Estate in Blaeanvon that's entirely made up of blast furnace slag. Although this bank is sparsely vegetation the plants that occur are worthy of mention. Field madder, carline thistle, wall pepper, and various cranesbill etc. etc. all jostle to for the nutrients required for growth in this hostile environment.
Away from the blast furnace slag and on to a nearby road verge I came across this attractive moth called Marasmarcha lunaedactyla, flying around its food plant is restharrow. A fly past black darter dragonfly and several marbled white rounded off the evening.
