Where Blaenau Gwent bleeds into Torfaen is the source of the Afon Lwyd. Amongst concrete, spoil, twisted metal and rich wildlife habitat is the trickle that runs southward to touch base with the River Usk. Today's early morning foray was more botanical than birding. Blue fleabane, several moonwort, and the usual plethora of orchids were notable, but the creeping willow (Salix repens) from railway clinker was the star attraction.
There were some butterflies as well, how about a dark green fritillary for starters? Then the first grayling of the summer struggling with the variable cloud cover. Also small skipper and small heath.
