Landes Cork Oak Harvesting

Levée du Liège des Landes

The hand-harvesting of cork bark from cork oak (Quercus suber) in the Landes de Gascogne — the northernmost cork oak zone in France. Cork is stripped from the living tree using a specialized axe (merlin à liège) every 9–12 years. The tree must not be wounded during stripping or it dies; the harvester reads the correct separation plane between cork bark and living cambium by feel and sound.
