Curly birch (Betula pendula var. Carelica) is not a separate species but is a genetical variation of Silver Birch, which grows only in small area in Scandinavia, Karelia and Finland.  

Curly birch grainy pattern wood belongs to the world’s ten most expensive among the exotic wood. Nevertheless, this wood is considered as a sustainable wood. Most importantly due to the fact, that most of the exotic wood comes from the tropical rainforests. Curly birch is a light-demanding and slow-growing tree and therefore this valuable quality wood is cultivated as stands in former agricultural areas or other nutritious, rich soils on sunny slopes.  

Even though Curly birch is considered as an exotic wood, the trade of this wood is not regulated with Cites regulation (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). So, the manufacturing and use of this beautiful exotic wood does not harm wildlife and natural diversity of tropical rainforests.
