This work nicely reminds us that forest recovery is fully underway in
the Eastern North America. There are
obvious limits that are been reached quickly because mature timber is harvested
fairly fast. What is forgotten often is
that the above ground mass is equivalent to the underground living mass. Thus a forest management strategy that
actually optimizes forest mass will generally maximize carbon retention.
This blog got its start arguing for a regulatory support system that
allows private forest management to be properly capitalized. I concluded that an agency should pay
directly for maintenance of woodlots on a fifty fifty joint venture basis for
effective control of the actual harvest.
Thus all woodlots would be uniformly optimized and harvesting would
occur under a global plan that is both natural and sustainable.
This takes us past the real problem which is the outright mismatch of
human time frames and forest time frames.
I believe it is plausible for a sustaining well operated forest system
to be naturally supportive of its joint venture partners who have a ownership
stake tied to the land.
Scientists Forecast Forest
Carbon Loss
ScienceDaily (Apr. 6,
2012) — When most people look at a forest, they see walking trails, deer
yards, or firewood for next winter. But scientists at the Harvard Forest and
Smithsonian Institution take note of changes imperceptible to the naked eye --
the uptake and storage of carbon. What they've learned in a recent study is
that an immense amount of carbon is stored in growing trees, but if current
trends in Massachusetts continue, development would reduce that storage by 18
percent over the next half century. Forest harvesting would have a much smaller
impact.
Jonathan Thompson is Research
Ecologist at the Smithsonian Conservation Biology Institute, Research Associate
at the Harvard Forest, and lead author on the paper which appeared in the
journal Ecological Applications in late 2011. "The rebounding forests
of New England provide a tremendous public benefit by storing carbon that would
otherwise contribute to climate change," said Thompson. To put these
findings into context he adds, "In Massachusetts, forests capture
approximately 2.3 million metric tons of carbon each year. That's equal to the
amount of carbon dioxide emitted from the energy used by one million American
homes annually." He and his coauthors were able to estimate the extent to
which development may chip away at that carbon sink, using an uncommon
collection of long-term data and a distinct form of research known as scenario
science.
For more than 30 years,
scientists at the Harvard Forest have scaled towers into the forest canopy and
measured the trunks of trees to track how much carbon is stored or lost from
the woods each year. This treasure trove of data is part of the national
Long-Term Ecological Research (LTER) Network, which is celebrating more than
three decades of research this month. This important milestone is marked by six
new papers just released in a special issue of the journal BioScience. The
forest carbon research is one example of participatory scenario science -- a
growing trend in ecology featured in a paper by Thompson, David Foster,
Director of the Harvard Forest, and their colleagues in
the BioScience issue.
Harvard Forest is one of four
LTER sites in the northeastern U.S. and was awarded a grant by the National
Science Foundation to join the Network in 1988. David Foster coauthored the
Ecological Applications paper of 2011 and co-edited the
new BioScience special issue. He notes, "With three decades of
data meticulously collected as part of the LTER Network, we have reached a
crucial transition where we are now able to tackle major environmental
challenges, such as the fate of forest carbon, across large landscapes."
Foster adds, "Over the
last two centuries, forests have stored more carbon with each passing year in
many parts of New England, but the turning point may be in sight for
Massachusetts and other urbanizing landscapes if recent development trends
continue." But that's not the end of the story for Foster: "The good
news is that forests are resilient and history is not necessarily destiny. Our
research makes a compelling case for expanding support for forestland
protection and for the efforts of private landowners to keep their land
forested. It reminds us that forests provide important infrastructure that we
should invest in, just as we do major civil works projects." Foster,
Thompson, and their colleagues made a case for doing just that in their 2010
work, Wildlands and Woodlands: A Vision for the New England Landscape. And, as
you might expect, that work was featured as a ground-breaking example of
science serving society in another of the recently
released BioScience papers.
