The {missing data} is used as delicacy . The {missing data} is used as " {missing data} " with {missing data} (_ - _) as its significant phytochemical. There is {missing data} extracted by cold pressing from the tree's seed/nut yielding 5% - 6% oil. The tree's wood is called {missing data} and has a density of 500 - 540 kg/m³. Regarding firewood production the tree's growing speed is slow, it's energetic value is 4700 ckal/kg and the wood's drying speed is slow. After 200 years the tree can be totally removed as it reached its commercial and ecological goal. Araucaria araucana has a lifespan of 1,000 years.
