They flew over it and met all the environmental authorities! They studied satellite pictures of the entire area! This is "good science?" Sheesh!
Unfounded conjecture is persuading nobody. Comments like yours have inspired
my own involvement in countering the wrong thinking out there. Stott backs
his findings with data, not conjecture.
What data??? I didn't see any data in that rant you copied. When Moore and Stott did their thing earlier this year, they didn't gather any data. They didn't reference any data by others either. These guys are CORPORATE PROPAGANDISTS, pure and simple. They're running interference for corporate clearcutters and high-graders who want to cut more rainforest timber. Here's what they were trying to counteract (copied from http://www.solcomhouse.com/rainforest.html):
Why is it that you expect of others what you don't provide? Researchers are entitled to make general statements via articles, based on their research. It isn't necessary to always include the data itself. Data is available upon request. Your own observations are deficient in data, appearing purely subjective and un-founded "rantings" as you put it. You make a charge here that is unfounded speculation out of inner fears. Find data and be objective. Otherwise, increase your respectability by either agreeing or disagreeing with statements, and offering your own thoughts based on something besides your fears.

A report in the current issue of Nature Magazine puts in doubt
the official Brazilian Government report of destruction of the
Rainforest. The real extent of rainforest damage in the Amazon
is more than twice as great as present estimates suggest,
researchers say.
The report says field surveys of logging and burning show far
more deforestation than satellite monitoring has revealed. The
researchers are based at several Brazilian and US institutions,
including the Woods Hole Research Center, Massachusetts.
They interviewed 1,393 wood mill operators, representing more
than half the mills in 75 Amazonian logging centers. They also
interviewed 202 landlords, whose properties covered 9,200 sq
km.
At todays satellite and aerial photo resolutions, there is no excuse
for inability to "see" the truth about rainforest conditions. Its there
and available for all to see. Order your own and take a look. It
doesn't take a genius. Mill location and available desired stock
are simply not in the same economic sphere.
One specific area of the Rainforest in Brazil was classified as
62% forested according to conventional deforestation mapping
. But the study found that only about a tenth of the area
classified as forest actually supported undisturbed forest. The
researchers say the failure so far to register the much greater
loss rate they have discovered is because the loggers reduce
tree cover, but do not eliminate it.
Good forestry. More thinning, less clearcutting, maintaining
sustainability.
[KD Note: This is called HIGH-GRADING, ie, cutting the best and leaving the rest.]
Have you seen the statistics on that? Without data I would assume the choices are
mostly species and minimum stump diameter. In remote areas like those, tree size
is extremely important for hauling economy. Mature trees are the 'victims', not species
composition.
The research also discovered
that fires burning on the surface consume large areas of forest
which again are not recorded. And where logging and fires have
caused damage the vegetation will grow back fast enough to
mask the true state of the Rainforest and distort the findings of a
satellite.
We have models for photo interpretation based on ground observation. Trained
interpreters aren't fooled- only novices are. Conversions to agri employ large-scale
burning of slash. If anyone has a 'beef' over that, it is with the agri folks there.
I see little GREEN complaint/connections to sharing of problems among agri
interests, which far out-weigh logging interests. It's the same problem in US
river bottoms. Agri is converting bottomland forest without a wimper from
opponents of clearcutting. I witness thousands of acres of conversion, and never
a protester.
"Satellite-based deforestation monitoring is an essential tool in
studies of human effects on tropical forests, because it
documents the most extreme form of land use, over large areas,
and at low cost. But this monitoring needs to be expanded to
include forests affected by logging and surface fire if it is to
accurately reflect the full magnitude of human influences on
tropical forests."researchers said in the report.
The author needs a remote sensing introduction course to get eyes opened.
The technology is sufficient. The problem is the resource in the wrong hands.
