Forage & honey flows
Sycamore and hawthorn dominate the Ogmore, Garw and Llynfi valley sides, providing a solid May–June flow above the terraces. Bramble is dense on coal-tip reclamations and forest margins above Maesteg and Ogmore Vale. Porthcawl dunes and the Merthyr Mawr sand-dune system support rest-harrow, bird's-foot trefoil, and marram — unusual coastal forage supplemented by the gorse and bramble of the Heritage Coast cliff path between Ogmore-by-Sea and Southerndown. Bell heather and bilberry contribute from the moorland fringe above Blaengarw and Nantymoel. Cowslip meadows at Merthyr Mawr and white clover in coastal pasture complete a long and varied season.
