> I think the point is that a forest reaches an equilibrium at some point. The forest has new trees growning and consuming co2, it has old trees still growing and consuming co2, it has dead trees/branches that releases co2. It's mostly at a steady state when it has matured. A forest can be in any unbalanced state at any age, it obviously depends on the ratio of dead to living trees and their size, as well as the climate. It's not a closed system that would need to reach equilibrium at some point. Forests will keep growing and trees will keep growing as fast as the environment allows and unsurprisingly, additional CO2 will help.
