The tree's wood is called {missing data} and has a density of 430 - 430 kg/m³. Regarding firewood production the tree's growing speed is medium, it's energetic value is 0 ckal/kg and the wood's drying speed is {missing data}. After 9 years the tree can be totally removed as it reached its commercial and ecological goal. Alnus japonica has a lifespan of 30 years.
