All:
As in all science, shouldn't there be a specific theoretical foundation for
such conclusions and at least some preliminary calculations to shoot at
first? Sounds like "range management" kaka de toro and a "carbon
sequestration" bandwagon to me. It needs some kind of proof, then some
retesting by truly independent researchers before applying it to policy,
such as chaining the trees and shrubs out and planting grass. Such an
"argument" can't be settled honestly on the basis of opinion.

Suggested reading: "Wildlife of Mexico" by A. Starker Leopold. (Especially
the "before" and "after" pictures of cornfield erosion. I'm not suggesting
that the case illustrated is comparable in every detail, only in principle.
Presumptuous "management" has trashed a lot of "range" in both the USA and
Mexico.)

Subject: [ECOLOG-L] C Seq Grass vs Wood
I am trying to settle an interesting argument and my
dear ecologgers:
I am trying to settle an interesting argument and my library resources are
quite limited, I hope you can direct me to reputable references.
There is the general belief (even academic) that forests or woodlands in
general can be a Carbon net sink, I am told that is not totally true, since
an early successional woodland, would probably be growing fast, respiring
also (so producing more C than sequestrating).
Now grasslands, if grazed properly (enough time given for recuperation) is
is argued that the root loss due to grazing can increase the net C content
in the soil (which is more stable than the above ground wood), even better
if high density grazing can topple residue and mix it with urine and feaces.
What do you think ?
