Bee swarm in Risca? Help is a minute away.

Risca is a valley town at the southern tip of the Sirhowy Valley, where the river meets flatter ground near Rogerstone and Newport. Twmbarlwm Hill — a distinctive Iron Age hillfort with a turf mound on its summit — rises prominently to the west, its heather, bilberry and gorse slopes visible across the borough; the hillfort and the woodland below it form a nature reserve carrying a diverse upland and scrub flora. The valley floor around Risca carries white clover on parks and allotments; sycamore on the valley sides gives a strong May flow. The Gwent Beekeepers' Association covers this area, and collectors are experienced with the traditional terraced streets and the newer estates that run up towards the hillfort.

Sycamore is the defining tree across these valleys, blanketing every south-facing slope and delivering a generous May flow almost regardless of colony location. Hawthorn on valley-side hedge lines and blackthorn in scrub above the terraces follows through late spring. White clover persists on allotment gardens, valley-floor parks and the gentler upland grazings from June onward. Bramble is dense on reclaimed colliery tips, forest margins and Sirhowy and Ebbw valley sides; bilberry and ling heather on the Gelligaer, Mynydd Islwyn and Mynydd Llangynidr plateaux provide a useful late-August supplement for hives on the valley rim. Alder and willow along the Rhymney, Sirhowy and Ebbw corridors contribute early pollen; meadowsweet and purple loosestrife on wetter valley-floor ground extend the late-summer flow. Ivy on old stone chapel walls and valley-side garden walls closes the year.
