Bee swarm collection in Na h-Eileanan Siar

Machair — the distinctive shell-sand grassland of the Atlantic coast — is the most celebrated forage environment of the Western Isles, supporting wild thyme, clover, bird's-foot trefoil, ragged robin and corn marigold in summer on North and South Uist and western Benbecula. White clover and red clover on improved croft grassland provide the main June-to-August flow across all the islands. Heather on the Lewis and Harris moorland — one of the largest continuous heather blankets in Britain — is the defining late-season flow, running from late July through September; bell heather predominates on the drier ground. Sycamore in the Lews Castle grounds and town parks around Stornoway provides a productive May flow in the only sizeable urban forage zone. Gorse is abundant on the roadsides and rough ground of Lewis and Harris from March into June. Bramble flowers on disturbed ground and roadsides throughout the islands from July into September. Ivy on older stone buildings and walls closes the season in October for colonies in more sheltered positions.

Western Isles beekeeping is affiliated to the Scottish Beekeepers' Association through a small local group. The machair honey of the Uists has a recognised distinctive flavour from the coastal wildflower grassland; heather honey from Lewis moorland apiaries is a traditional product. The Atlantic climate brings warm but often wet and windy summers that require careful hive management; the mild maritime winters allow colonies to survive at lower stores than in the Scottish mainland.
