Forage & honey flows
Sycamore dominates the valley sides throughout the borough, delivering a generous May flow in every settled community from Briton Ferry to Glynneath. Hawthorn and blackthorn on the valley-side hedgerows and upland field margins follow through late April and May. White clover is abundant on valley-floor parks, sports grounds and the coastal amenity grassland around Swansea Bay; bramble is exceptionally heavy on reclaimed colliery and industrial land throughout the valley floors. The lime avenues of Margam Country Park provide a distinctive July flow; Margam's veteran chestnut and oak supplement through spring. Bilberry and ling heather on the Mynydd y Gwair and the upper Dulais and Neath Valley plateaux offer a late-summer supplement for colonies on the valley rim. Alder and willow along the Nedd, Dulais and Afan corridors contribute early pollen; the Kenfig sand dune system brings sea buckthorn and dune-slack flora within reach of coastal apiaries.
