    Why Himalayan balsam is a problem in Hirwaun

    On Hirwaun properties, Himalayan balsam fires seed up to seven metres, smothers native bankside vegetation and leaves bare soil that erodes into watercourses each winter. Hirwaun sits at the top of the Cynon valley near the Brecon Beacons, where industrial estates and roadsides spread weeds from site to site.
