The runic corpus is epigraphic rather than a proven oracle. In modern rune divination Berkano is read for birth, growth, nurture, new beginnings and renewal. These associations belong to the twentieth-century reconstructionist and esoteric revival, popularized in the 1980s, and are presented here as a symbolic tradition rather than an ancient practice or a claim about the future.
The birch's association across all three rune poems with new growth, leaves and fertility despite the tree's own botanical tendency to produce seed without a fleshy fruit, a detail the Old English poet notices directly, underlies the modern divinatory keyword sense of Berkano as birth and nurture. As with every rune in this atlas, the specific practice of drawing Berkano as an oracular sign for childbirth or new beginnings is a twentieth-century addition, not a continuation of any use attested in the poems themselves.
The Armanen-descended rune-magic tradition transmitted into English chiefly through Thorsson's work also treats Berkano as usable actively rather than only read passively: chanted aloud as galdr, or carved into wood, metal or a bind-rune combining several staves, for an intended practical effect. No source earlier than the twentieth century attests any such active magical use of this specific rune, and the practice should be understood as a modern reconstruction built on the reconstructed name and the rune poems rather than as a recovered ancient technique.
