Bee swarm collection in Caerphilly

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.

The Cardiff, Vale and Valleys BKA covers the western and southern parts of the borough; the Gwent BKA covers the eastern valleys including Blackwood and the Sirhowy and Ebbw corridors. Both associations maintain active swarm rosters and the compact valley geography means response times from trained collectors are short across the borough.
