Payeur-Poirier and co-workers have measured CO2 fluxes in black spruce forests of different age in the US. They find that a recently harvested (8 years) forest area is a net carbon source, while a young forest (33 years) is a carbon sink. A somewhat older forest (105 years) still acts as a carbon sink but not as much as a young forest. Read the whole article in Agricultural and Forest Meteorology.
