Masur Birch (also known as Karelian Birch) is not a species in of itself, but rather a particular grain figure that occurs in various species of European Birch. The result is a beautiful marble like figure – a mix between burl and birdseye.
The cause of this figure is uncertain. Some say that it comes from a tree’s reaction to invasion by the larvae of the Agromyzia carbonara beetle, but the general opinion seems to be that it is hereditary, classifying the name of the variant as Betula pendula var. Carelica. Regardless of the exact origin of the figure, it provides us with stunning and unique looking lumber, just begging to be showcased in some fine woodworking. It is most commonly used in accent details, turned objects, knife handles and other small specialty items.
Sustainability: This species is not currently listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Fine furniture, knife handles, turnings, veneers, and other small specialty objects.
Comments: Veneers of Masur Birch are rotary cut (like Birdseye Maple) to ensure the best figure is extracted for the veneer.
