Sound public policy would (a) protect old forests, (b)
grow young forests into older forests (aka, longer rotations), and (c) when logging, retain significant residual trees both live and dead.
While logging does create young forests that absorb carbon, the process of harvesting large old growth and burning logging debris transfers most of the carbon to the atmosphere leaving a «carbon debt» that takes
the growing young forest centuries to repay.

young trees and remove competing species, Reyes tells the group, even though the slow -
growing mahoganies won't be large enough to cut for timber for another 75 years.
However, a new University of Minnesota study with more than 1,000
young trees has found that plants also adjust — or acclimate — to a warmer climate and may release only one - fifth as much additional carbon dioxide than scientists previously believed, The study, published today in the journal Nature, is based on a five - year project, known as «B4Warmed,» that simulated the effects of climate change on 10 boreal and temperate tree species
growing in an open - air setting in 48 plots in two
forests in northern Minnesota.
A more sound approach would recognize that (1) converting old
forest to
young forests releases significant amounts of carbon (both above and below ground), (2)
young forests are only good carbon sinks if they are allowed to
grow and hold onto the carbon for centuries, yet there are too few economic incentives for doing so, and (2) the fraction of carbon that is put into long - term storage after logging is very small, i.e. old
forests are better at storing carbon than our disposable culture.

One of the long - ago NASA studies concluded that
young (
growing)
forests remove far more carbon that mature
forests.
Replacing old slowly
growing forest by
young rapidly
growing one is useful only if the old trees are either stored so that they will not release their carbon back to atmosphere or used to replace fossil fuels or materials, whose manufacturing causes CO2 emissions.
They report that stopping deforestation and allowing
young secondary
forests to
grow back could establish a «
forest sink» — an area that absorbs carbon dioxide rather than releasing it into the atmosphere — which by 2100 could
grow by over 100 billion metric tons of carbon, about ten times the current annual rate of global fossil fuel emissions.
Reindeer herding in the Siberian tundra, will also tend to affect the
forest, so that e.g.
younger saplings are killed allowing mature trees to
grow, whereas when grazers are not protected by humans, the balance in the ecology is different as the herds are graze only where they are safer from attack.
Other studies have separately confirmed that old
forest giants paradoxically store more carbon than
young, fast -
growing competitors, and that natural, highly diverse woodland is a better instrument for atmospheric carbon absorption.
Conversely, using
young forests — which
grow faster than more mature ones — as the carbon offset mechanism in the EF balance sheets eliminates the entire global ecological overshoot.
In many
forests, these fallen trees actually become «nurse logs» — foundations from which
young saplings
grow.

young, healthy,
growing forests managed by state, local, and private landholders, and the choked, dying, or burned federal
forests,» McClintock said.
