Massaranduba is renowned for its ability to last many decades even in extreme weather conditions. Density and hardness, as discussed above, plays a large role in that. Natural resistance to water penetration and rot/decay also contributes to its longevity. The forests, from which they evolved, experience 100-400 inches of rain per year. That is up to 8-10 times more than anywhere in the United States. Evolutionary responses to this heavy rainfall have made this wood naturally resistant to water penetration, mold, rot and decay.
