- Range: Karelian Birch Burl is a strain of European Birch found in Finland and Russia. Most trees grow in Minsk, Vitebsk and Grodno regions of the Belarusian forests of Poland.

- Properties: The highly-decorative Masur (or Karelian) birch, from Betula verrucosa var. carelica has ripple texture combined with attractive dark streaks and lines. Creamy white with tan "flames" and dark brown burl outlines.
- Note: Also called Alpine Burl or Karelian Burl after the Finnish province of Karelia where it is often found. The high figure found in this wood is caused when the tree heals the damage done by an invasive boring beetle. The beetle infestation leaves the trees stunted and sometimes deformed but produces wood with small twists and swirls that highlight the darker, burly figure.
