Crown Vetch on the Neath Canal

Crown Vetch (Securigera varia) is a scarce alien in the west and the appearance of a large population on the Neath Canal just west of Glyn-neath following clearance work suggests a seed bank may have been present from a formerly established population.

A more established alien is Pearly Everlasting (Anaphalis margaritacea) which has its stronghold in South Wales and it is a common sight along forestry tracks and disturbed mineral soils in the north of the county, such as here on Hirfynydd.
