The highest NPP is usually observed in middle-aged trees (30-60 years old) as they have reached their maximum growth potential but have not yet experienced age-related decline in productivity. Trees that are over 100 years old may not have the same rate of photosynthesis and growth due to natural aging processes. The younger trees (0-1 years old) have not yet reached maturity and do not have a high biomass to contribute to NPP. The trees between 1-10 years old are growing rapidly, but their overall biomass is not as high as middle-aged trees.
