Of course they have stocks that far exceed young managed forests (they store a lot). But forests do not continue packing biomass on indefinitely (the rate of sequestration slows and eventually stops). See this summary of Malmshmeimer (2011) [1]: “Trees do die, and at a rate that eventually reaches some kind of a stasis at a landscape level,” says Fried. “In some stands, up to one hundred percent of the trees will be killed by a fire or insect outbreak; other stands con- tinue to grow, but over the entire forest you’ll eventually reach a plateau, after which the net in-forest growth and carbon accumulation rates decline—eventually to zero.” Many pro- tected forests on public lands, especially those in parks and wilderness areas, are no longer increasing carbon storage, he says.
