  Uses
  Larch wood is valued for its tough, waterproof and durable qualities. Top quality knot-free timber is in great demand for building yachts and other small boats, for exterior cladding of buildings, and interior paneling. The timber is somewhat resistant to rot when in contact with the ground, and historically was used as posts and in fencing. However, European Standard EN 350-2 lists larch as slightly to moderately durable; this would make it unsuitable for ground contact use without preservative in temperate climates, and would give it a limited life as external cladding without coatings.
  The hybrid Dunkeld larch is widely grown as a timber crop in Northern Europe, valued for its fast growth and disease resistance.
  Larch on oak was the traditional construction method for Scottish fishing boats in the 19th century.
  Larch has also been used in herbal medicine; see Bach flower remedies and Arabinogalactan for details.
  Often, in Eurasian shamanism, the "world tree" is depicted as specifically a larch tree.  Planted on borders with birch, both tree species were used in pagan cremations.
