[Terrapreta] Earthen Kilns Conjecture

[Mark Ludlow]

Jeez, Greg,

 

Those Weyerhaeuser ads really worked for you, didn't they?

That my friend, is much about what I'm talking about!

 

I will add that going in every so often ( I would say every year ) and
totally clearing a acre or two in a random pattern, promotes healthy forest
by increasing species diversification - it increases not only plant species,
but also animal species that relies on the plants that come about from the
increased light than reaches the forest floor.

 

I would say a 30 year ( or more ) rotation ( with a few areas always kept
clear and several area never touched ), depending on the species and the
forest type.

Hi Greg,

 

Culling (selective cutting) in an old growth forest, to remove diseased
trees, suckers, smaller than 3" diameter trees, and such isn't a bad idea at
all, I don't think.   The forest arisings can be a significant source of
biomass.  Removal of dead and decaying woody biomass can also reduce the
fire danger by removing the easy fuel.

 

As I have understood forest growth, young forests have fast growing trees
and little decay.  The older, larger trees in older, more mature forests do
use less CO2 per pound, if you will, than smaller, younger trees, but large
trees still take up large amounts of CO2 during the growing season.  The
other effect of decay in old growth forests is what makes them less able to
sequester carbon than younger forests.  They lose CO2 to decay almost as
fast or faster in some places than the CO2 taken up by the trees when they
are growning.

 

Regards,

 

SKB
