Ancient Bark is an uncommon type of wood in Valheim. It comes from Ancient Trees in the Swamp and is used exclusively for crafting. You will need a Bronze Axe to fell ancient trees.
Don’t worry about stockpiling ancient bark because it’s only used in a few items and cannot be burned in a charcoal kiln. At some point, it will just become dead weight in your storage.
