Joe,
I have no doubt that money was the prime motivator of the lumbermen.
Always has and always will be. I was thinking more in terms of the
forestry academics at Humboldt State. I didn't say that, but that
was what I had in mind. Now that big Don is retired and in a
reflective period of his life, I am interested in hearing his
thoughts.
In therms of locally, when did clear cutting rear its ugly head? I'm
surprised that the local forestry establishment decided to undertake
such a risky strategy. They can quickly have their heads handed to
them in Massachusetts. They must be living in a goldfish bowl.

*********************************************
As a certain extremely elderly industrial timber beast forester in
Mass. loves to say- clearcutting was the only form of harvesting
until the mid twentieth century when skidders became common. Back
then most timber in this region was of relatively low value and
there was still a market for fuel wood in rural New England- and
there was a market for some sort of wooden boxes- I'm still not sure
about those boxes, but that's what he loves to tell us about. Then,
with the rapid expansion of the American economy after WWII- there
arose a big market for quality hardwood. The J.W. Kelly company in
Pittsfield was one of the first in the region to develop the new
hardwood market- expanding until it had 7 mills in western New
England and eastern NY. So, the more valuable trees were worth far
more than the lower value trees. With plenty of acres to cut, it
made perfect sense to just cut the best trees and move on to the
next property- hence the rise of high grading.
But the industry always loved clearcutting- to them it's
"clean"- and it takes no thought- in particular, it takes
no forester. It's not easy nor safe to drive your skidder through
the woods- leaving trees with some marginal value. Loggers really
hate it when foresters leave good trees- trees that the forester
won't want damaged- trees that could drop branches on your head.
Russ Richardson has reported on industry "foresters"
ranting against him for leaving good trees, saying, "what right
do landowners have to leave such good trees?".
So, when any excuse for clearcutting comes along- the industry loves
it. It seems to me that the first excuse was when the state decided
that all those plantations established in the 1930s should be wiped
out. The state really HATES those plantations. It's true that some
were/are in poor condition. In fact, many plantations on state land
were/are known as "the crooked forests"- they were Scotch
pine which came from a bad seed source- almost every tree in those
plantations were severely deformed. So, OK- I could see cutting most
of them, while leaving a few for aesthetic reasons. <G> And,
some of the red pine plantations also were rather mediocre- either
because they were planted on inappropriate soils or because they
were never thinned- developing into bean poles of barely alive
trees. The state might claim there was no market for thinning red
pine- but, they could have thinned them "precommercially"
by chain saw girdling. They also seem to hate Norway spruce
plantations- but I can't imagine why- most which I've seen consisted
of healthy trees of good form- but, I suppose that's irrelevant to
the state. The excuse is that they're "not native".
Smartwood seems to be pushing this- having told the foresters at the
Quabbin that they should wipe out all such plantations on that
property. Thus, this viral hatred of plantations led to the first
large scale clearcutting on state land -and they now had a pseudo
scientific rationale. In the October Mt. State Forest they've now
carried out hundreds of acres of clearcuts- beginning with the
plantations and then mediocre quality hardwood stands, some of which
do make sense wiping out- except for the fact that all this
clearcutting is right along the main roads through the middle of the
state forest- so that October Mt. now looks like a huge wasteland of
clearcuts- like much of northern New England. (a side note- during
the first energy crisis in the early '80s, the state made a push to
sell fuel wood trees to individuals- what they called
"cut-a-cord program"- one of the state's mgt. foresters
hated the idea- he preferred doing big timber sales- so he tried to
sabotage the idea by marking all the nice big roadside maples along
miles of the roads in the middle of the state forest- which of
course got residents of nearby Town of Washington in an uproar- I
recall driving through the forest and couldn't believe how awful it
looked with those roadside trees whacked)
Now that they're big on clearcutting, they have to further develop
their rationale- now it's all about enhancing biodiversity.
Clearcutting will now be a major forestry "tool" on state
forests and the primary tool on state Fish & Wildlife lands.
I'm not against clearcutting where it really makes sense such as
regenerating previously severely high graded stands.
The state F&W agency- at meetings a few years ago claimed that
they wanted to increase stand sizes from 7 acres to 50 using even
aged mgt.- which of course means clearcutting. Then, when I
challenged them, asking if in fact that meant that they want to do
mostly 50 acre clearcuts, they denied it- but they do claim that
some clearcuts up to 30 acres or so has a place in their system.
Many times at many meetings I've asked how clearcutting enhances
biodiversity- they claim that some species need those huge clearcuts-
despite the generally understood science that more complex forests
offer more biodiversity. I do commend the state's F&W top
forester, John Scanlon as he does attempt to communicate with those
who dispute the clearcutting "regime". Some months ago he
gave me a long list of research papers that justify this
clearcutting. I've just had a chance to track down these papers and
I intend to study them.
So, the answer to your question, Catheter Kid, is that it's the
state which is pushing clearcutting. Though industry would love to
clearcut- they find that it's not economical due to the large number
of low value trees- many of which were left from THEIR previous high
grading. So, on private property - clearcutting is still rare,
except properties being developed. The quality of forestry work on
private property is getting better as the consultants have struggled
to get clients in competition with the industry- with no thanks to
the state's weak and ineffective "programs". The bureau of
forestry now claims that most harvesting is "long term",
that is, real forestry- but, that's an exaggeration as it's not too
difficult to move from high grading to "long term" simply
by leaving some fair quality trees and cutting some poor quality
trees- a fancier form of moderate high grading- is still the most
common kind of harvesting in the state. To spoof this fancy high
grading- I've written a one act play: http://forestmeister.com/duh/one-act-play.html
Now, to those who've often claimed that what happens in Mass. is
irrelevant because it's just "postage stamp sized state"-
in fact, having spoken to foresters all over North America, what
happens here is the same as what happens everywhere- state
boundaries have little significance to the "wood
industry". And, what happens here in Mass. is very significant
because many major progressive movements in American history started
here- like the American Revolution, the early days of the abolition
movement, the first public schools, the first wetland laws, etc.

Folks,
In the last year, I have been to several U.S. Forest Service
meetings
and field trips where foresters and biologists have stated the
"need"
for more large openings (i.e., clearcuts) for biodiversity. The big
focus is on species, primarily birds, that are declining in the
Northeast and are dependent on or associated with early successional
habitat. I have also communicated with a U.S. Fish and Wildlife
Service biologist who justified clearcutting on a national wildlife
refuge in northern Vermont for the same reason. There, the project
was specifically about woodcock.
To their credit, for the most part, the projects that these agencies
are pushing right now are adjacent to existing roads, in relatively
young stands. But not all are in this way relatively
"benign." On the
White Mountain National Forest, the agency is proposing going into
several inventoried roadless areas.
The F.S. folks are particularly enamored with a researcher at UMass
named David King. His work up in the Whites is apparently showing
striking responses in bird diversity with larger clearcuts (can't
remember the size now, maybe 20+ acres?).
I'm interested in hearing more from others on what they think about
this issue and how they are dealing with it. What I have been saying
to the agencies is that if there is a need for more early
successional habitat (and I am still unsure what I think about
this),
then let's focus on the private timberlands. The public lands should
be the places where we allow large mature forest blocks to remain
and/
or develop over time. I am worried that this new drive for/
justification for clearcutting will create more fragmentation in our
forests and diminish the pool of older forests that could become old
growth within a few decades if we left them alone.

Mollie:
In Minnesota we did a range of natural variability analysis for
every major
forest ecosystem type in the state. Basically, we made estimates of
the
proportion of habitat in various stages of succession under the
natural
disturbance regime for each forest type and compared that to the
distribution among successional stages on the landscape, using a
technique
I developed in my Ph.D. Thesis during the 1980s. In MN, we have more
early
and mid successional habitats and much less late-successional
habitat than
would exist under the natural disturbance regime. I don't know how
such an
analysis would come out for New England. The MN analysis was
actually
started by the Ecosystem Management Program at Boise Cascade Corp.,
and
later on the DNR and Forest Service started using it.
Although we can't go back (and shouldn't try to go back) to the
so-called
natural disturbance regime, in some forest types some of the
successional
stages have an order of magnitude less acreage now than before
European
settlement, and that tells us that species living in that stage have
much
less habitat than before. The issue in MN has evolved into whether
there is
sufficient representation of all successional stages on the
landscape, and
there is a lot of debate over what sufficient representation means.
The
Minnesota Forest Resources Council brings together people from the
timber
industry, environmental organizations, government agencies, and
researchers
on a regular basis to discuss these issues at the same table and
make
recommendations to the legislature.

Lee, I'm not in the habit of reading PhD thesis so I find this a bit
confusing. How do you evaluate the following: a stand that has been
managed
for a long time as an uneven aged stand? It might have trees of all
sizes,
possibly in patches or groups, or just randomly- this is the type of
silviculture I prefer- but, if you're counting acres in different
size
classes, how do you measure this type of stand?

In Mass., and I suspect throughout the Northeast, it has been
claimed that
most forests are in the mid aged strata, with less young forests and
even
less old forests- most are even aged due to old field abandonment. I
suspect
they throw in the high graded stands as even aged too- to hide the
fact.
Very few forest stands have been managed for any length of time as
uneven
aged- perhaps it's simply not recognized for what it is.

Perhaps we can't go back, but I'm not so sure we shouldn't go back,
at least
for some good percentage of forests- the future old growth forests?

Many species can inhabit more than one stage- I suspect there aren't
all
that many restricted to one stage.

Let's just try imagining the following: what if most forest land
became all
aged- due to uneven aged silviculture. Then, you'd most likely have
many if
not most species of wildlife present in most stands, all other
things being
equal. Not having a PhD in forestry or advanced education in systems
ecology
like Gary Beluzo- despite that, I'd suggest that such complex
forests that
would develop- would have great complexity and it's complexity of
structure
that offers biodiversity- then again, I'm only a field forester, so
what
could I know?

It's about time some scientists deconstruct that idea- uh, well,
sure- some
clearcuts might add some variety to the landscape, but the more I
read
research papers by "wildlife experts" the more I get the
sense they want
most of the forest land to become even aged- via clearcutting- a
system well

money by
firing most of their foresters - yet, the irony is that this
simplicity is
supposed to give us enhanced biodiversity. It makes you wonder how
such a

Woodcock and partridge- the 2 "game birds" which now
become a
rationalization for extensive clearcutting- how cute. In the town of
Peru,
MA at 2,200' elevation, a huge clearcut occurred across from my
house- to
inspire the partridge and woodcock to take up residence- several
years
later, there are still none- both like brushy areas in the midst of
other
forest types and wetlands. But when you do a clearcut, you get brush
for
only a few years- then you get extremely dense sapling forests with
little
brush and little "old field species"- a fact usually
overlooked in the
lustful quest for more clearcuts. In fact, there now seems to be
zero
wildlife there- a stand that once was a nice mixture of spruce-fir-hdw,
small fields, and an apple orchard- and yes, they cut down the
orchard with
mature trees which used to bear abundant fruit! In that stand I and
my
neighbors used to see bear, moose, turkey and other species- well, I
did see
a chipmunk there once. <G>

And, I wonder what sort of bird diversity you'd get with large
uneven aged
forests- carefully managed to have healthy trees of many species of
many
ages, while leaving snags, and many huge, old trees with hollows-
and many
trees simply for their beauty. Nah, they probably haven't gotten
around to
doing that research yet- it's too complex, takes too long- and it's
not as
much fun as a humungous blown out clearcut- and it's clearly against
the
party line, so funds will be scarce.

>>to the agencies is that if there is a need for more early

With uneven aged silviculture, done right, you get early
successional habit
too but in smaller doses- spread throughout the forest- all mixed up
with
mid aged and old aged forests. I've seen patch clearcuts as small as
1/16 of
a acre which regrew white birch, pin cherry, black cherry and other
early
successional tree species and ground vegetation. Now, when I
challenge the
state of Mass. Fish & Wildlife agency about this- they claim
that some
species REALLY NEED 25 acre clearcuts. Well, maybe a few do, but so
what? Do
the needs of a few rare species of birds which were probably not
here 500
years ago necessitate humungous clearcuts, when such clearcuts
clearly are
not great for so many other species, and clearly is not good
economics- not
to mention extremely ugly?
>>then let's focus on the private timberlands.
We don't need humungous clearcuts on private timberlands either-
though it
will continue on large industrial forest lands- because it's simpler
and
more profitable in the short term- yet in the long term it isn't
profitable,
which is why so much of the New England "northern forest",
having been
"managed" by the wood industry, is now a wasteland being
sold off to
developers. Just think if those firms had been practicing great
silviculture, leaving the best trees to advanced age- with uneven
aged mgt.-
we'd now see millions of acres of extremely diverse forest land with
far
greater biodiversity and worth many times as much, but nah, I must
be wrong-
because the all knowing forestry establishment has claimed
otherwise.

Joe:
The gist of your comments is that uneven-aged stands provide good
habitat
for a lot of species and we should have more of them on the
landscape.
That really agrees with range of natural variability analyses I have
done
in the Midwest--what is mostly missing from the landscape are what I
call
'Old multi-aged stands', which were very common in northern
hardwoods,
hemlock, oak, white pine and spruce-fir forests. Under a natural
disturbance regime, they were created by individual tree deaths from
old
age, and occasional storms that created scattered gaps of various
sizes.
They are analogous to well managed uneven-aged stands. Except in
boreal
systems with frequent crown fires, these old multi-aged stands made
up
50-90% of forest landscapes under the natural disturbance regime,
and it
seems to me that today we have a far lower proportion than that. My
guess
is that in New England, a natural range of variability analysis
would show
proportion of uneven-aged forests at least as high or higher than in
the
Midwest. Because your fire regimes and storms are pretty mild by our
standards, fewer even-aged stands would be created by a natural
disturbance
regime.
BTW--we do have some Forest Guild people in MN (including me), and
their
presence does tend to pull the center of the debate more towards
long-term
sustainability.

Mollie-
While it's somewhat different out here in the west, there is
rational and logic associated with timber harvests which 'mimick'
the temporal and spatial disturbance regimes of the region, east or
west.
Thinking of Massachusetts, known wind event cycles come to
mind...variable size openings are created with each hurricane's
passage, in a cyclic fashion across the New England landscape.
Choosing the shapes and sizes consistent with that of the wind
events provides the surrounding environs (flora/fauna) with a
disturbance cycle that the area has shown over time, sufficient
resilience to restore itself. Ground disturbances should be scaled
to match that expected of tipover mounds and pits...soil compaction
should be avoided.
Here in the west, we also have wind events, but usually they play a
secondary role. These days, wildfires (ALWAYS exacerbated by the
role that winds play!) are headlining our natural disturbance news.
They also have variable shapes and sizes, variable burn severities
(degrees of resource destruction), and restoration return cycles.
Re fragmentation, my concern is that main tenets of conservation
biology are followed...fragmentation (particularly when mimicking
natural disturbance regimes) is less of an issue than maintaining
unbroken wilderness areas with substantial continuous connections
with other wilderness areas. I think that the myth of squirrels
being able to travel by treetop from Florida border to
Maine/Wisconsin has been sufficiently debunked.
But, as you say, by all means protect what old-growth areas we have
left, especially if they can be surrounded by marginal old-growth
buffers.

Though hurricanes have certainly done some damage in New England- in
particular central New England from that nasty one in the '30s (?)
which
leveled thousands of acres- the suggestion that hurricanes were
widespread
and thus were a primary cause of forest regeneration throughout the
region-
I believe, is not proven. Harvard Forest in Petersham, MA makes a
big deal
of hurricanes since much of their several thousand acres was
"reset" by that
hurricane - but I haven't seen one yet in western Mass. in my 58
years.
Actually, I don't know either- but it would be interesting if any
researchers have addressed the question of just how much of the New
England
forest in 1491 originated from hurricanes.

Joe-
In partial answer to your posted question below, I'm cutting/pasting
the following snippet (italics are mine):
"We applied this method to New England, USA, examining
hurricanes since European settlement in 1620. Results showed strong
regional gradients in hurricane frequency and intensity from
southeast to northwest: average return intervals for F0 damage on
the Fujita scale (loss of leaves and branches) ranged from 5 to 85
years, average return intervals for F1 damage (scattered blowdowns,
small gaps) ranged from 10 to more than 200 years, and average
return intervals for F2 damage (extensive blowdowns, large gaps)
ranged from 85 to more than 380 years. On a landscape scale, average
return intervals for F2 damage in the town of Petersham MA ranged
from 125 years across most sites to more than 380 years on scattered
lee slopes. Actual forest damage was strongly dependent on land-use
and natural disturbance history. Annual and decadal timing of
hurricanes varied widely. There was no clear century-scale trend in
the number of major hurricanes.
"The historical-modeling approach is applicable to any region
with good historical records and will enable ecologists and land
managers to incorporate insights on hurricane disturbance regimes
into the interpretation and conservation of forests at landscape to
regional scales."

My comments are not meant to diminish the importance of your 58
years in the area (remarkable continuity compared to us
westerners!), but to point out that much of what goes on in our
forests occurs in temporal scales that extend beyond our own
lifetimes...which is NOT to say that what you or others do, has no

I was a timber marker in the late 80's on the Daniel Boone NF, and
have a sense of the historical impacts of ownership...the Redbird
Ranger District (was a Purchase Unit when I was there) was
originally owned by Ford Motor Company in the early 1900's, and
subsequently by Peabody Coal. During those ownerships, considerable
resource extraction occured (timber/coal) and significant
reclamation and revegetation was needed to repair increasing damage
to the landscape hydrology. The Redbird Purchase Unit was initiated
to reclaim the strip mines, and through silvicultural efforts
mitigate what havoc the logging practices wreaked.
For my part, carrying 50 pound sacks of lime, followed by 50 sacks
of chemical fertilizers up to the strip pits was part of the
'hands-on' reclamation. The silviculture practiced then was to
create even-aged stand compartments that favored existing high value
species, through coppice reproduction. Compartments varied widely in
size and shape and were predominantly based on species
dominance/topography.
I haven't been back (I was there from 1984-1989), so I can't relate
the success of my efforts, but I can tell you with high confidence

What do you fellows think of clear-cutting a patch of timber and
then
planting back to the species that originally dominated the same
site?
For example, cutting a patch of loblolly pine and then planting the
same ground back to longleaf pine, which was the species that
dominated the same site back in pre-settlement days.
Maybe I'm wrong, but I can't see anything much wrong with that. It
might look ugly as hell for a few years, but then it gets back to
the
way it was supposed to be all along. At the same time, native
grasses/
understory can be be restored to gradually approach what the entire
ecosystem looked like way back when.

Gary,
I can relate to what you are talking about. Simply put,
clear-cutting makes sense where it makes sense. The problem I see is
that those advocating its widespread use to create wildlife habitat
often overstate their case and don't thoroughly investigate
alternatives that could provide the same specialized wildlife
habitat plus meet other important objectives. This is where the
experience of field foresters like Joe Zorzin, Russ Richardson,
Ehrhard Frost, Michele Wilson, etc.is invaluable. They know how to
make things happen on the ground.
In the case of taking down loblolly pine to recreate longleaf pine
habitat. Go for it.

A major disadvantage of planting is that's very expensive. Who will
pay for
it? Whenever possible, IMHO, good forestry means let nature plant
the trees.
Even if the desired species isn't close by, if it's an ideal site
for that
species- somehow mother nature seems to find a way.... I recall a
Guild
visit to the Quabbin Reservoir in Mass. The forester, Bruce Spencer,
showed
us some locations where he planted oak and they didn't take well,
but in
other areas where they were not planted- they planted themselves
even though
mature oaks were not close by. The problem on the Quabbin had been
excessive
deer population due to a no hunting rule. Once hunting was allowed,
regeneration occurred abundantly.
Certainly if funding can be found, and it's strongly believed that
"natural
regeneration" won't happen any time soon- or that invasives
might take over-
or the site is critical for other reason- then go for it.
Once the "original" species has reclaimed the site, either
by planting or
naturally- then it should be possible to keep it their via smart
silviculture, without further "artificial" planting.
As to loblolly being the original species there- is it possible that
it
wasn't the original dominant species there before the arrival of
Indians?
The thought that much of the American southeast was
"naturally" pine species
seems odd- in such a wet climate, it seems to me that it would have
been a
much more mixed forest with dominate hardwoods prior to man made
fires.

Mollie,
Some studies have shown that clearcuts larger than 10 acres or so
can
cause soil nutrient depletion along with the disappearance of
mycorrhizae which aid trees in the uptake of water and nutrients.
Thus
future forest productivity may be negatively affected a bit by very
large clearcuts. Other studies have shown that the mycorrhizae
recolonize quickly and there isn't much nutrient loss. In addition,
the
Quabbin Reservoir also did a study on how much coarse woody debris
should be left on the forest floor to for nutrient recycling when
they
were liquidating their red pine plantations and came up with 2
cords/acre.
Huge clearcuts like the flattening of whole townships in Maine in
the
70's and 80's doesn't happen anymore in the NE, but the MA Fish
&
Wildlife Dept. is promoting clearcuts of up to 25 acres which I
think is
too big. I would prefer 5 acres at the most. In badly degraded
stands
(those that have been high-graded more than once), then it is
sometimes
better to cut all the junk that's left and start over. But promoting
clearcutting as some sort of panacea to improve the populations of
neotropical songbirds, etc. has been vastly overstated. Better to
kill
all the feral cats and all the house cats that kill millions of
birds
every year! (or tie a bell around your damn cat to scare the birds
away!) There are also countless miles of "edge" along our
roads. Mowing
regimes along our roads can be adjusted for the birds.
As Joe says, it takes no thought to arrange a clearcut. Just flag or
paint the boundaries of the cut and call in the machines. Much
easier
and cheaper than having a forester judiciously mark each tree to be
cut.
Even a caveman could do it!
Yes I've seen how well the clearcuts have regenerated in the WMNF.
From
a viewpoint, they look a different shade of green. Up close newer
clearcuts are thick with northern hardwood regen. Some paper
companies
used to spray to kill the hardwoods since they preferred spruce-fir
but
not anymore.
Small clearcuts may be appropriate on industrial forest land but you
could never sell them to the small woodlot owner (10-200 acres). At
best
they might buy into 2 acre patch cuts to create more uneven age
classes.
It would be much better to encourage landowners to reclaim old
fields or
keep existing fields open since if left alone to grow back,
non-native
invasive plants often colonize which could also be a drawback to
clearcutting (in southern New England - not so much in northern New
England where the invasives are much less of a problem).
In sum, clearcutting should be used only when necessary and the
openings
kept small.

Don, Joe;
Yeah Harvard Forest did what I thought was a stupid experiment. They
pulled down a bunch of trees on purpose to simulate a hurricane to
study
how the forest recovers, etc. Why do that? It's all in the
historical
record anyway. They also did a study on high-grading (North Quabbin
Timber Harvest Study) but they copped out on the conclusion.
Anyway hurricanes have had a significant impact on forests in
southern
New England. About once every hundred years or so a big one comes.
The
pit and mound topography you see in the forest is old blowdowns
rotted
away. Check out Tom Wessels "Reading the Forested Landscape-A
Natural
History of New England". An excellent book but like Harvard
Forest,
Tommy cops out with respect to the devastating impact that
high-grading
has had on the forest.
In my travels in the backwoods the biggest trees of course usually
predate the 1938 hurricane and these are located on the lower slopes
that afforded more protection from the big wind of '38.
The management plan for the 55,000 acre Quabbin Reservoir Watershed
seeks to produce a multi-aged forest that will be more resilient
when
the next big wind comes.

Yes, a major reason to clearcut is that it's a no brainer - a second
reason
it's pushed by "wildlife experts", though not explained to
the public, is
that hunters LOVE clearcuts because they think it will be easier to
find
deer. After all, state fish & wildlife agencies are in the
business of
serving the hunting and fishing crowd, which is why I humorously
refer to
those agencies as Hook 'n Bullet agencies.
Hunters love to park their macho pickup trucks along a road and not
have to
drive too far- to a spot where they can see a long distance, such as
through
a recent clearcut, without having to walk too far, which of course
is hard
work- and it's easier than sitting up in a tree waiting for your
prey to
walk by, a behavior I find unmanly- at least ENTS people climb trees
to
measure them and for the thrill of course. And, if the hunters get
lucky and
succeed in blasting a chunk of hot lead into the body of a soft,
warm,
cuddly creature like a deer- it should be easier get it out through
the
clearcut than through deep woods.
I also think many hunters are actually somewhat fearful of
"deep, dark"
forests. Over the years I've talked to many hunters and many have
said, "you
mean you go deep into the woods without packing iron?". They're
amazed that
I do so- despite those deep, dark woods having "dangerous"
animals like
bears, snakes, possibly mountain lions, coyotes and others.
OK, I'm exaggerating- I have no beef with hunters- it's their karma
when
they blow away a beautiful creature, not mine. It's just that I
think the
Hook 'n Bullet agencies love clearcuts because hunters love
clearcuts- yet
they don't say that, they say that it's to enhance biodiversity. In
fact, I
believe the mission statement of the state of Massachusetts's Hook
'n Bullet
agency is specifically to enhance biodiversity- but, then again, who
do you
think wrote that mission statement if not the committee's set up to
do so-
appointed by politicians- and who gets appointed to such a committee
if not
people friendly to the hunters who love clearcuts? (showing my
cynical view
of governments- which I happen to believe are nothing more than
fancy Mafia
rackets)
We all know that government is loaded with disinformation,
especially
regarding foreign policy- but this is also true when it comes to
natural
resource agencies- which is why a few of us specialize in
deconstructing the
official nonsense such agencies pump out to justify their juicy
careers.
Joe
PS: I notice now on cable TV there are channels dedicated to
hunters- you
can now thrill to watching them hunt- usually 2 or more will go out
wearing
microphones so you can listen to their profound strategies: "yo,
Billy Bob,
see dat big buck up yonder? Let's git him." One day I watched a
hunter "bag"
a mountain lion- the hunter sat down next to his prize- and, believe
it or
not, while raving what a beauty is is, he started petting it! I

Joe,
Longleaf pine, not loblolly pine, was the dominant upland species
across much of the lower South in pre-settlement days. With
exceptions
for floodplains, it stretched all the way from east Texas to the
Carolinas and on up into parts of Virginia, if I'm not mistaken.
And all fires are not man made, though you are right about the
Indians
using them. Natural fires from lightning strikes can and have
occurred. These fires once slowly burned across much of the South
for
days and weeks on end.
It is very interesting, the relationship between longleaf pine and
fire. The long needles, the resins that encouraged fires, etc.
It was interesting to see some of the loblolly and slash pine
plantations in coastal Mississippi after Katrina, snapped like match
sticks. The longleaf pine, the golden oldie of the area, stood up
much, much better. I was told by foresters down that way that
roughly
70% of the longleafs remained standing in areas where nearly all the
loblolly went down. It is also a tree that holds up much better
against the Southern pine beetle, black turpentine beetle, etc.
From what I've read, the U.S. Forest service is returning to
longleaf
pine in many areas down South and yes, assistance in plantings is
sometimes possible. Because of the "grass stage" that the
longleaf
goes through before terminal growth and the modern day suppression
of
fires that it needed to dominate back in the pre-settlement days, if
one waits for natural regeneration in the face of the more
aggressive
loblolly, sweet gums, oaks, etc, they will be waiting a long time in
many situations.
I could go on and on, and hope I made at least a bit of sense, but
gotta hit the road. Love them longleafs. :-)

Joe,
Longleaf pine was THE dominant forest type in the Southeast Coastal
Plain, covering over 22 million acres from Louisiana to SE Virginia.
The great thing about longleaf restoration is that fire is a very
efficient tool for accomplishing it. It there are nearby longleaf
stands, the planted loblollies can be cut, the remnants burned, and
loblollies, wiregrass and the fire dependent species return.
Lightning from summer thunderstorms was the engine for most fire in
longleaf pine forests - remember, though recieving high rainfall,
the
coastal plain has sandy substrates and dries out quickly, resulting
in
frequent (3-5yr) low-intensity fire.

Managing a forest to resist hurricanes, the various thunderstorm and
derecho events,
and tornado's is unproven rubbish.
Normal level winds from microbursts, weak (EF0 to EF1) tornado's,
and hurricane winds
under 90 mph (all you will ever see in most of New England), will
only take out
trees that are weak, with defects, or with poor root systems. Gee
that sounds like
natural management doesnt it? The better trees will stay, even aged
stands or not.
Once you get to a critical level, which varies from site to site,
usually around 100-110 mph,
everything will go. The 1938 hurricane produced winds at that level
in some places, but not
most of the inland ones.
A tornado that hits this level will take out anything and
everything, matter not how even
aged it is. It looks like a huge vacuum cleaner went through.
Derecho's are particularly good
at blowdowns, as seen in Lee's area quite often. Example: The
Adirondack state forest
blowdown in 1995. They have to hit the 90+ mph range normally to do
a blowdown, or else
they will take out just the weaker ones.
Events that cause that level of damage are very rare, at least in
New England. The far
far majority of events fall into the lower wind speed levels that
manage rather than
destroy. I produced data for Agawam back to 1850, detailing the wind
speed that
affected the forest there. Its been exposed to virtually everything,
derecho, hurricanes,
and even an F3 tornado. The F3 tornado is the ONLY event that
produced any level
of serious wide area damage. It was a path about 200 ft wide by 3
miles or so, then it
degraded into a microburst. It destroyed about 10 acres of forest,
totally in that
path. Tornado's will not destroy wide areas. Only a hurricane, or
derecho that
contains multiple microbursts will accomplish that task.
Forests that are left intact will resist normal wind damage since
they provide more
deflection and absorbing of wind, rather than open areas with less
targets. DCR did
a test cut on the Mt. Holyoke range that shows what happens when you
open up
or overcut forest. The big seed trees left had their roots exposed,
and there were
less deflections, resulting in the wind taking out quite a few of
the big seed trees left
during a microburst. Winds only hit 70 mph maximum. You can see this
also
at October Mountain, where trees left have been blown over by wind
now that
they are exposed. Its a delicate balance, and not one that uneven
aged management
is going to fix.

I agree- yet, this is now part of the forestry party line,
especially coming
from Harvard Forest. The real hurricane to worry about is the
hurricane of
high grading. Just imagine a force that blows through the forest
removing
the healthiest, nicest, most valuable trees- leaving the deformed,
defective, sickly, low value trees- that's what high grading does-
yet, it's
often done in such a way that it doesn't really look all that bad to
the
naive- to the naive, it might look as good as great silviculture,
since they
see that some trees are left- the forestry establishment has worked
very
hard to come up with "best management practices" (which
are neither best nor
are they mgt. practices) to teach loggers to minimize ruts, damage
to
residual trees, minimize erosion, minimize fire hazard, minimize
damage to
boundaries, prevent damage to wetlands and rare species, etc.... in
order to
MAKE IT LOOK BETTER to get the enviro/eco crowd off the back of the
"wood
producers" (who don't produce wood- they produce wood products-
it's the
forest which produces the wood, with the help of foresters) - the
establishment has done virtually nothing to ensure proper
silviculture, in
order to have future forests be "healthy" and wealthy in
the interest of the
forest owner, society at large, the well being of the forest.
Instead, they
now push for massive clearcutting.
Instead, forests can and should be managed for complexity to enhance
real
biodiversity and to make them more economically productive over the
long
term- based on growing trees with very high stumpage values-
something that
may hurt the local wood industry and even put them out of business,
but so
what? The forest doesn't belong to the local wood industry. Uneven
aged
forests with many species will do this- but, to paraphrase Hillary
Clinton,
"it takes a forester". <G>
There is absolutely NO CONFLICT between the most sophisticated kind
of
eco-forestry and the very best enhancement of the wealth producing
capacity
of the forest for the forest owner- NONE- only in the minds of the
idiots
who run the forestry world. They always make it seem like there is
this
conflict- they love to say really stupid things like: "you like
wood,
dontcha? you use toilet paper dontcha? then stop trying to influence
our
sophisticated, science based forest management" as if what
they're pushing
is forest management, rather than just enhancing the short term
profits of
the wood industry and the joy of hunters.

The silvicultural practice of uneven aged management is not to grow
a
hurricane resistant forest which is rather unlikely as you suggest,
but
rather to promote different age classes so the younger seedlings,
saplings,
etc. will be there to grow into a new forest if and when the overs

blown over. Otherwise, a new forest will take much longer to develop
when

worse than any

I suggested that this should be a new diorama at the Fisher Museum

Harvard Forest, but alas I guess the powers that be there didn't
think
it that important. But the fact is that it has been the major
negative
influence on private forest land all across the eastern US. But
since
state forest bureaucracies allow anyone to do forestry work, the
"Hurricane of High-grading" is what you get. If they had
to try and
survive selling improvement cuttings on high-graded lots, I bet
they'd
change their tune real quick.
Well I checked on one of my chipper crews this morning and yeah I'm
not
following the 2 cord/acre of coarse woody debris rule left on the
forest
floor, but often times aesthetics are more important to small
landowners. There's still some scattered brush, etc and only about
1/3
of the volume was taken out of this lot that had never been cut in a
century. Nutrient recycling is important but taking out the crummy
pine,
red maple, and low quality oak while leaving most of the best red
oak
and pine is far more important and its not easy finding good
operators!
If you're taking out less than 1/2 the volume, then this nutrient
recycling bit is less important than if you were clearcutting. It's
always good to do it right the first time! I even flagged around a
diseased beech grove where there is a colony of pileated woodpeckers
so
the operator wouldn't disturb those magnificent birds.

It's that ancient hatred instilled into all baby foresters- to
absolutely
HATE "overmature" trees with a passion- and to love heavy
cutting in order
to "regenerate" baby forests. When you train people to
think a certain way
or to do a certain type of work- that's what they think and do- this
is the
problem with any sort of education that is NOT LIBERAL- all these
specialty
trades and professions- they find it hard to think on their own-
especially
when following the party line is how you advance in your career-
such as
Jim DiMaio, our state Chief Forester who spent over 30 years in the
USFS
before becoming the state Chief. You don't do 30 years in such
agencies by
thinking on your own.
Forestry education really needs to be massively overhauled- as I've
suggested many times, with little support (not counting Bob Leverett
of
course <G>)- it should start with an undergrad
"pre-forestry" education in
biology and ecology- then and only then should you go to
"forestry
professional school", where you'll learn ecoforestry infused
with a
sophisticated understanding of the rates at which trees can produce
value-
in order to be able to have your cake and eat it to. <G>
Regarding that tornado that hit Gt. Barrington area- back in what,
1996?- it
did massive damage to several of my client's forests. One was a gem-
a 25
acre stand of near old growth white pine. Almost all of the pine
were
"overmature"- but in the early '90s I carried out a "silviculture
project"
there- I only marked a third of the basal area. The logger did a
great job.
A few years after that harvest, the tornado wiped it out- leaving
several
hundred huge trees all piled up like the "pick up sticks"
game. I got the
same logger back to clean up the mess. That was very dangerous work
since
the trees were piled up in a mess- many broken and half sprung- it
seemed
that the entire mess of trees was all in a big knot- that moving any
of it
might unleash a chain reaction.

PS: regarding forest policy- in college I took a course on forestry
policy-
at that time, I just wanted to get a good grade, so I did something
reprehensible- I looked up the prof's PhD thesis then I did my final
term
paper- more or less paraphrasing his brilliant ideas from his
thesis- and of
course I got an "A" in the course. I should have learned
from that. In other
courses, I constantly challenged what they said and was often
accused of
being "radical". A prof. McConnell taught "forest
management", the
penultimate forestry course- in one of his lectures (back in '71 I
think) he
ranted against the class saying, "your generation has no
character" (that
is, he hated hippy radicals) as the crew cutted 'Nam vets in the
class
cheered - I stood up and ranted back, "your generation is
napalming innocent
people working in their rice paddies". His Scottish complexion

Near a very small town of Stans, Austria (about 25
miles east of Innsbruck) a tornado ripped across the
valley, down one side and up the other side, about 30
years ago. You can still make out the path today.
Austia didn't and doesn't go around clearcutting all
its forests down in order to prevent the trees from
getting blown over.
I think that Austria would have a less of chance of a
tornado that NE but even here in the midwest, torando
alley, we don't clearcut the forest to prevent them
from being blown down.

Actually, I keep it all rather simple- working with small
properties, I
don't have the luxury of thinking about designing an array of
habitat types-
but, I suggest even attempting that is "thinking too
much". Instead, when
I'm marking a stand, I simply do it on a tree by tree basis. If a
stand is
fully stocked- any stand, young, old, whatever mix of species- and
whatever
its passed history- once it's fully stocked (at the "A"
level of stocking
from a forester's point of view)- I unconsciously use what I call
the "1/3
rule"- that is, I lower the basal area by about a third. I do
that by
removing the 1/3 of the trees which are producing value at the
lowest level
(that is, based on return on existing value). By this method- the
stand will
be more economically productive that before. Trees of all sizes and
species
are removed- while trees of all species and sizes will remain. The
stand
remains at least as diverse as before and with more value producing
capability. Some very nice, very valuable trees are left if they
still have
sufficient "productive juice" in them. Not marking such
very valuable trees
hurts when the bills are piling up- but, it's not my objective to
grab the
wealth now (for the owner and myself). But, just knowing that if I
mark a
veneer quality tree could put $50 in my pocket for 5 seconds of
work, the
devil begins whispering in my ear ("don't worry Joe, nobody
will notice or
care, the owner will probably like the extra money, the state guys
couldn't
care less, the SAF will cheer you, the logger will like you- and
those bills
are piling up"). Then the angel whispers in my other ear (no,
Joe, don't do
it- it's against the Guild's "first principle"- it's high
grading- you'll
lower biodiversity- the future owner will earn much less- the
children 7
generations in the future will have an inferior planet- and you'll
earn so
much bad karma that you'll reincarnate as a Republican- and you
surely don't
want that". So, the choice can be tough, but that last bit by
the angel
usually works. <G> What's amazing is- that if temptation
succeeds for people
in other trades and professions- there's almost always a more direct
price
to pay- people will find out- but in forestry, when the devil
convinces you-
there is no price to pay, other than that bad karma.
When I say I reduce the stand by a third- it's not just the stand as
a
whole, it's throughout the stand, as uniformly as possible- so, when
I'm
marking, I try to see only the trees within a small circle and
reduce the
basal area within that circle- as I move, the circle moves, so it
gets
complicated- the decision on each tree is a function of that tree
and the
other trees within that circle surrounding that tree. So, it's never
just
about an individual tree- the decision that a tree is
"mature" is always
about CONTEXT. If I happen to find, say, 3-4 trees close together
that I
feel should all come out (such as a group of large highly defective
pines)-
I'll mark few other trees in that area, so that any imaginary circle
dropped
anywhere in the stand will almost always show a 1/3 marking of the
basal
area. This has always been my theory- so one day I decided to go
into a
stand that I had recently marked but had not yet been cut and took
10 prism
plots. Not only did the % that was marked for the entire stand come
to 1/3
but on most of those plots it was 1/3.
So, again, the theory is to continually enhance both the diversity
of the
forest AND long term ability of the stand to produce economic value-
not so
much in terms of dollars per year, but rate of return on existing
value. I
hold that this fusion of ecological concern AND hard core concern
for the
financial side of the work is the method that should be used for
most
harvesting. I believe most arguments for clearcutting (in the NE
that is)
are nuts- ecologically and economically, the same for diameter limit
harvesting. The real proof is the results. Whereas the established
view is
that you grow a timber stand, then wipe it out- either all at once
or in a
series of shelterwood cuts- then start over. By this method, the
average
value of timber at any point in time is NOT much. By always leaving
valuable
trees and building up that value and never removing much of that
value- the
average value over time is much higher- which in essence means that
there is
more investment in the forest.
It's as if you started off with a dollar in the bank. You could let
it grow
to $2, then remove it all, then start over again by adding a penny.
Or, you
could let it get to $2, then lower the investment to $1.35, then let
that
grow to $3, then drop it to $2, then let that grow to $4, then drop
that to
$3, etc., etc. A fusion of hard core capitalism and eco
considerations.
As to the suggestion that the owner might be a little old widow in
need of
surgery or a family with the kids going to college, so they need to
whack
the forest to raise the money- that's absurd- in a case like that
it's not
too difficult to alter the method so that instead of lower the basal
area by
a third, perhaps it could go down by 50-60% but still leaving the
trees with
the most potential to grow value as a function of existing value-
and, by
marking all of the poor quality trees- the final sale price will be
close to
or exceed the liquidation value- without destroying the golden
goose- but
when that golden goose is cooked, there is a measurable loss of net
present
REAL ESTATE value to the property. And, if the forest is so damaged,
there
is an unmeasured lost to all society and the planet. If the owner
continues
to insist, as the Forest Guild's First Principle says, it's best to
walk
away.
But, back to the question of habitats- I don't really have to think
too hard
about it- just leave the forest in good shape, with ever larger
trees over
time- and of course, leaving snags and hollow trees, and good
buffers along
wetlands, etc. Such uneven aged forests, I hold, are far superior
for most
wildlife species- as you have large, healthy trees producing
mast/seeds,
openings for browsers, hollow trees for dens, a mix of species- a
very
complex forest- not an autopoietic forest, but the second best
thing. <G>
(or should that favorite term of Gary Beluzo be "auto-
poetic"?

> Joe, no need to apologize for your lack of an academic Ph.D.

Of course my saying that was deeply tongue in cheek- but I won't
elaborate.

Ray:
All changes in successional and/or developmental status of a forest
favor
one set of wildlife species and disfavor another set of species (and
there
may also be a few species insensitive to successional or
developmental stage).
Clearcutting always changes the developmental stage of a forest
(stages of
structural development range from young stand initiation to old
multi-aged,
and obviously stand initiation is created by clearcutting), and it
may or
may not change successional (i.e. species composition) status of the
forest. Some clearcuts maintain the same successional status that
already
exists, and some send the forest forwards to a later successional
stage or
backwards to an earlier stage. The effects depend on the
successional
status of the overstory and understory tree species, the ecosystem
type,
and silvicultural systems and harvesting methods. For example, in MN
clearcutting an older aspen forest during winter can release
thousands of
small balsam fir seedlings (which survive harvest under the snow),
and
create a young but nevertheless late-successional fir forest.
Clearcutting
an aspen stand without a fir understory will allow the aspen to root
sprout, and the same early successional stage will come right back.
Clearcutting a sugar maple forest without earthworms will generally
allow
maple to maintain dominance, whereas cutting one with earthworms
will allow
green ash, birch and oak to take over (no maple seedlings in the
understory, ash, birch and oak can germinate on the bare soil
created by
the earthworms).
If the plans you mentioned were done by competent foresters, they
should be
able to give similar information for the ecosystems involved. What
acreages
of the proposed cutting will take place on different ecosystem
types, what
are the likely successional pathways in each case, what wildlife
species
will benefit, and why is it important to benefit those species at
this
time? If they can't answer those questions they don't know what they
are
doing.

Lee,
Thank you for the information.
About a year ago, John Scanlon, who is chief forester for F&W,
wrote an
article for the Massachusetts Sierran about birds that need early
successional habitat and what F&W is doing to provide it. Joe
Zorin
challenged the concept, and John sent a long bibliography about the
subject to the email list where the discussion was going on. I don't
have that email, with the bibliography, handy, but I'm sure it can
be found.
Frankly, it does sometimes seem to me that people on this email list
who
expect to be considered experts in one field do not accord the same
respect to other people who are experts in their fields. I wish we
had
less flaming of people who are not members of this list.

...We have been provided a multitude of science that demonstrates
that clearcutting benefits wildlife little if any in the far
majority of cases.
If early successional was so rare, why are so many shelterwood
harvests
planned that virtually eliminate it? We have had several wildlife
biologists, that
are authors on the subject, state to us that the only thing that
benefits in the
majority of cases of "wildlife enhancement", are the
hunters, who can now find
deer etc. that are drawn to these areas.
I really have little to do with the ongoing argument, and just
inquired for scientific
viewpoints. Im not an expert in that field, which is why I asked of
those that may be.
Clearcuts on public lands should be avoided (in my opinion only)
unless needed for
restoration of high graded stands, or a clearly demonstrated need to
artificially enhance
species at specific stands. Im sure the DFW and DCR will respond as
to why this is needed.
Just FYI, all of the bird experts we asked that had viewed Robinson
stated flatly that
the species listed in the cutting plans they had seen for other
sites would benefit little by the plan
as it was presented. Im sure DFW can find some source that will say
otherwise though.

I found the one note we had regarding a specific plan..
One harvest on DCR lands was touted as "to enhance the
population of scarlet
tanagers". John Hutchinson and others stated that "yes it
will do that, however,
it will have a highly detrimental impact on the neotropicals that
visit the site,
and they are far more imperiled". "The neotropicals and
other species that are in
that area need canopy for protection".
Its also interesting to read the green certification audits, which
specifically say:
"use the biodiversity argument more to convince the public to
accept harvesting".
Suddenly, we have all these timber harvests to "promote
biodiversity". I would hope
the environmental groups examine this carefully and not get roped
into more
green certification hooplah at the expense of the public lands.
Im not against DFW doing legitimate work to promote species, but
when these
are planned with participants with known slanted interests, it bears
watching.
Also need to note that there were NO listed birds on the NHESP list
at Robinson
for example. Turns out, 12 of the 28 listed species were found at
Robinson and
identified by the survey done 2005 to 2007, ending at our bio blitz.
Its quite possible
they dont know all the species at other sites as well.
None of this should be controversial, keep it informative and
scientific.

Hello Folks,
I recently attended a conference that was intended to set the
restoration priorities for the Southern Appalachian National Forests
for the next couple of decades. And, of course, the early
successional issue came up frequently. For those of you experienced
with the ESH (early successional habitat) issue here in the east,
the
golden winged warbler is the poster child carted out to show folks
with a holistic view of ecosystems that early successional habitat
benefits species, and rare ones, other than those humans like to
shoot. In researching golden winged warblers, I noticed a few
trends: 1) Journals dedicated to wildlife want to clear cut to help
the golden winged warbler 2) Journals covering the golden wing that
have more rigorous scientific credentials never recommend creating
more early successional habitat to favor golden winged warblers. 3)
Partners in Flight is probably an industry front group like the
Ruffed
Grouse Society
I gleaned the following information from a review of the literature:
1) Golden winged warbler populations have been declining for at
least 50 years
2) Declines are based more on damage to wintering habitat in the
tropics than nesting habitat here
3) Golden winged warbler is expanding its range northward -
climate
change anyone?
4) Golden winged warblers are also declining because of
hybridization
and competition with blue winged warblers
Hope this helps for all of you folks who don't buy the
"need" for ESH
as a justification for liquidating forests on our public lands.

Ray-
400% of what, 30 acres? that would be 120 acres...that would be okay
by me...problem with numbers is that they don't always paint the
whole picture...if they're already doing 12,000 acres per year, then
I'd be against it, under any circumstance I could envision.
Somewhere in between lies a level of clear cutting that might be
appropriate for the intended objective (benefitting wildlife). And
just 'acres' is a potentially misleading number...the arrangement,
the orientation, the array of sizes, the locations and how they
relate to the topography/landscape are freaking critical.
Do they mimic natural disturbances for the area they are planned in?
Do they retain unmerchantable material for wildlife use, or do they
burn the slash on site? Has anybody contacted David Kittredge of
UMASS regarding his long running (I assisted him in the early 90's)
Grouse Society small, non-industrial, private land ownership
workshops/information regarding timber management at the NIPF level?
Just a few thoughts Ray, from afar...

Josh,
You put your finger squarely on the underlying issue that drives the
early successional arguments and both their savvy and naive proponents.
Here in Massachusetts, I fear that the overarching strategy is
little more than to soften public opinion toward either forest
liquidation by industrial interests or unnecessarily intensive
management for commercial species by BOF or wildlife species by DFW
on the public lands. In the end, the mantra of the BOF trying to
promote their green certification agenda in Robinson SP pretty well
said it all. Experts consulted by The Friends of Robinson SP over a
period of many months, one by one, shot down the BOF's simple-minded
arguments, whether the purported need was for early successionally
bird habitat of species that were over-represented when
Massachusetts was 70% to 80% cleared or mis-stated natural forest
trajectories - trajectories that presumably were leading to forest
decline and therefore justifying BOF intervention. But when put to
the test, the BOF couldn't even recognize vernal pools or be
truthful about BOF's real intentions. How many collective years of
forest experience did they have? And what did it add up to? The idea
that DFW needs 25-acre clearcuts to insure sufficient habitat for
the species they are promoting brings us to the series of points
made by Lee Frelich.

Im not sure of all the particulars yet. I did however visit one site
where
DCR was doing some clearcuts, in patches (patch cuts, not clearcuts
they
call them). It was horrendous. They left plenty of material and
didnt burn,
but ruined a nice piece of native forest to do so. In the meantime,
we observed
several deer, and several moose, all hiding in what was left of the
thick canopied
forest and avoiding the clearcut areas! There is oil in wet areas,
large left pine logs
in piles, slash in streams, and an overall mess. The sierra club
head here in Mass.
visited the same site and commented to us on it.
They did make one large clearcut a couple of years ago at this site,
and it is now
adorned by deer stands nailed into trees at the edges. Wildlife
benefit? BLAH.
Maybe chipmunks :) There is another site they cut in the past for
grouse, which
there was a small population of at the site. Now there are none.
This is a complex issue,
and there likely can be some benefit,but I am skeptical of anyone
that claims they are
benefitting wildlife while embracing and following green
certification on the same lands.
Seems the real underlying reason might be driven by timber
production....

I agree, there is plenty of early successional habitat to go around
in the
East. What is largely absent in the East are large blocks of later
successional and old-growth forests. Everything that remotely
qualifies for
wilderness designation under the Wilderness Act of 1964 on federal
public
lands in the East really ought to be designated ASAP, in my opinion.

Jush, FYI, this was stated as justification for one of these.
According to information the DFW Forestry Program received from the
Natural
Heritage & Endangered Species Program (NHESP), and from the
Northeastern
Research Station at UMass, Amherst, state-listed rare species such
as the
Eastern box turtle and Barrens Buckmoth, as well as species of
regional
conservation concern that are experiencing long-term population
declines
such as Brown Thrasher, Prairie Warbler, Eastern Towhee, and
Whip-poor-will,
have all benefited directly from the semi-open habitat conditions
created by
the mechanical harvesting operation, and from the subsequent
prescribed fire
regime that is being used to maintain this fire-adapted pitch
pine/scrub oak
ecosystem. In addition, on-going research demonstrates that during
the
post-fledging period, forest birds that nest in relatively mature
forest(our
most common habitat type in Massachusetts) tend to bring their young
into
early-seral habitats to exploit food and cover resources
"
I can tell you for certain that the Eastern Box Turtle prefers
cooler, canopied habitat.
That is the NHESP recommendation for the species as well. I took
part in some research
on that subject at the local park, which supports a fantastic
population of them. By the way,
the NHESP database showed ONE turtle report in the last 20 years,
which was used in
the forest cutting plan. WAY underdone.
As for the others, those more informed than I can comment.
Also the "risk of wildfire" is being thrown around again.
That one surface after
the California incident, with the DCR forester claiming red pine
stands that were dead
are a threat. That one fell apart when experts on the subject looked
at them. Any
and all reasons that the public will be scared by, or fall for, have
been used to justify timber
harvesting. If not for the various groups that are now questioning
this,
they may prevail.

The operative phrase is in your last paragraph - competent
foresters. I don't take pleasure in being so critical, but the sheer
amount of incompetence and deception on the part of BOF over the
Robinson SP situation that required citizen activists to step up to
the plate to prevent exploitation and expose the deception has left
an extremely sour taste in my mouth. It has grown ever more sour
with time. Maybe I'll get over it, but as of now, my trust in BOF is
hovering around the zero mark. DFW appears to be following the same
trajectory. With these comments I'll return to more positive
endeavors. Gary Beluzo and I have an article to complete, I have a
book draft to begin, and Larry Tucei Jr. and I and hopefully others
have a live oak project to launch.
