CBC had a disheartening story yesterday about the presence of the
Emerald Ash Borer in Bedford. It seems that it's now just a matter of
time before ash trees in the province are history.
The forest behind our home opened up tremendously with the deaths of all
the Beech trees; Ash trees are one of the more common remaining
deciduous species.

Hi Peter & All,
   Not good news but does anyone know if the affected trees are
provided with ample area for infiltration of water and aeration? I have
seen "shade" trees in urban areas that will never be more than sick
runts and naturally trees without ample air and water will be more
likely to be overwhelmed by insects. From what I have seen of Halifax
prior to about 2008 (not there since) the trees were well sited.

On Wednesday, a fine sunny, warm day, our south-facing windows were covered
with little black randomly moving spots, which proved to be *Orchestes fagi*,
Beech leaf-mining weevils. They're waiting impatiently for the beech leaves
to emerge and turn much of our property into what you describe, Peter --
dead beech trees. They began the insult last year, and this year I expect a
pretty thin canopy by the end of June. That, plus a change in the way water
accumulates and sticks around more than it used to, causing some tree
dieoff, not to mention much higher and regular winds (and a neighbour who
would rather have a well-groomed yard than those pesky natural trees)
causing blowdown, all adds up to a seriously challenged bit of forest here
on the N. Mountain. Can't wait for the Emerald Ash Borer!

As the old joke goes,
Q: "When is the best time to plant a tree?"
A: "About thirty years ago."
Probably about time to start putting some replacements into the ground - neither Beech nor
Ash, of course.

Good point, and considering the vulnerabilities of American beech, ash, hemlock, and (Oh,
yeah!) American elm, it’s probably better to plant a variety of species.

More important than ever to advocate for leaving healthy standing old forests intact,
including standing and fallen deadfall. More than ever, we need good woodpecker habitat to
beat back these diseases! Note - The IUCN has redlisted all north american native ashes as
critically endangered. We here in Nova Scotia are the last bastion for this endangered
genera and its dependent cascading ecosystems. So far the only effective biological
control mechanisms are some asian wasp species (must be introduced) and our native
woodpeckers. BTW the province should list all native Fraxinus sp. as endangered, not just
black ash, and leave wide conservation buffers around stands known to contain ash so as
not to bring in the borer on forestry equipment.
With kindest regards

Hi Mary and all,
   Assuming the Emerald Ash Borer can fly, wide conservation buffers
to keep Ash protected, sounds as effective as a water bucket made from
1/2" hardware cloth.
   Black Ash is no doubt endangered but in woodland with heavy soil,
White Ash is often abundant. The only defense which I can envision
against the EAB or equivalent is adequate thinning so three trees are
not competing in a space adequate for one and stand diversity. Insects
have a robust survival strategy, safety in numbers, and woodpeckers will
never subdue an insect invasion.

New subject: Orchestes is out and about
From Doug's observations on the North Mountain, it sounds like the
Beech Leaf-mining Weevil (/Orchestes fagi/) a.k.a. "Evil Weevil", as
coined by folks in Eskasoni, is already out and ready to pounce on new
beech leaves as soon as they unfold. How sad.
The weevil is ramping up to attack the American beech trees again this
spring; what few remain and thrive after the much earlier introduction
of beech bark disease, an invasion from Europe nearly a century ago.
If it is gathering on the North Mountain, it is also out in the warmer
parts of the Annapolis Valley. I have yet to see this part of the life
cycle, so will head out to search for it this weekend. I am curious
about the reported clicking sounds they make. Do you hear them, Doug?
The beech trees are not ready to leaf out yet, so maybe the weevil will
find itself out of sync and starve. That would be nice.
If I stand out there with a large vacuum cleaner when they are
swarming...? I guess that sounds desperate and futile... So many of
these weevils are likely being moved about on firewood as little
stowaways. I hope our provincial parks will switch to providing
firewood to perhaps keep out infested firewood imports with campers and
keep out the weevil for as long as they can. Valley View Park will most
certainly be devastated, and likely soon. I hope they have a plan.

New subject: Orchestes is out and about
Dear All,
   I wish to make a few general comments about insects and trees.
   There seems to be a general perception that insects which attack
trees move about largely when logs or firewood is moved. While this no
doubt can happen insects often move without human help. Compared to
insects we are the new kid on the block; thus they got around without
our help.
   If you fell a healthy White Pine on a calm, warm sunny day it will
soon attract an assortment of insects laying eggs in or on the bark free
(smooth thin "bark"; just undifferentiated epidermis) as opposed to the
thicker multi layered bark followed by Cleridae looking for a meal of
insects, eggs or to lay eggs where the young will likely find larvae or
eggs to eat.
   (Drawing on memory so details may be faulty.) Cut a small Ash
(smooth bark) and leave it where it was but leaning against another
small Ash and within one fine day (sometimes hours) the cut Ash will
have any small round holes and the intact tree will be without holes.
   Thus tree health conditions interaction with insects.

New subject: Orchestes is out and about
Dave and all:
At the risk of falling into a never-ending debate here, I will clarify
that there is a gigantic difference between _native insects _and an
_invasive insect_ that threatens to permanently remove a formerly
keystone tree species from our forests.
Orchestes fagi is an invasive species, moved here by humans from Europe
and recently introduced into Halifax and Sydney ports. it's a total game
changer. Both CFIA and CFS scientists have identified its key dispersal
mechanisms. Long distance dispersal is associated with human
movements. This particular insect is capable of stowing itself into
cracks and crevices of any tree species where it spends most of its life
cycle apparently. Anyone cutting any species of tree can accidentally
and quite unknowingly move this pest. It thoroughly kills beech after
several years; a tremendous loss to wildlife like black bears who fatten
up on beech nuts during mast years, as most folks here would already
know. Essentially, our most nutritious "wildlife' tree of the Acadian
forest is rapidly disappearing across NS, and there is barely a whisper
across NS of its enormous loss.

will not respond further-there's info on-line/.)

New subject: Orchestes is out and about
Dear All,
   Some may remember an outbreak of caterpillar (Army worm ?) which
defoliated many trees for several consecutive years. The trees bounced
back. Spruce Bud worm is another matter because the young needles are
eaten before they have emerged from the bud.
   So far I have never found a nut bearing Beech in my North Alton
woodlot. After I bought it in 1980 I found one large dead Beech and one
large dying Beech. But nearly every year since I find young Beech just
at the edge of my pick and shovel roads. Jays apparently find them
elsewhere ( I suspect sides of a very steep gully) and plant the seeds
in the moist soil at the edges of my roads. And these trees so far are
free of canker. There are numerous old Beech south of Kentville on,
where else, Beech Hill. Scruffy looking and cankered but there and west
of this patch clear to the the 101 I have over 50 years or so seen many
Beech seedlings; wide cotyledons just above the litter. But Bears who
relied on Beech mast, in the vicinity of Kentville, for food would be
seriously underfed.

Dave and all:
At the risk of falling into a never-ending debate here, I will clarify
that there is a gigantic difference between _native insects _and an
_invasive insect_ that threatens to permanently remove a formerly
keystone tree species from our forests.
Orchestes fagi is an invasive species, moved here by humans from
Europe and recently introduced into Halifax and Sydney ports. it's a
total game changer. Both CFIA and CFS scientists have identified its
key dispersal mechanisms. Long distance dispersal is associated with
human movements. This particular insect is capable of stowing itself
into cracks and crevices of any tree species where it spends most of
its life cycle apparently. Anyone cutting any species of tree can
accidentally and quite unknowingly move this pest. It thoroughly
kills beech after several years; a tremendous loss to wildlife like
black bears who fatten up on beech nuts during mast years, as most
folks here would already know. Essentially, our most nutritious
"wildlife' tree of the Acadian forest is rapidly disappearing across
NS, and there is barely a whisper across NS of its enormous loss.

Dear All,
   I wish to make a few general comments about insects and trees.
   There seems to be a general perception that insects which attack
trees move about largely when logs or firewood is moved. While this
no doubt can happen insects often move without human help. Compared
to insects we are the new kid on the block; thus they got around
without our help.
   If you fell a healthy White Pine on a calm, warm sunny day it
will soon attract an assortment of insects laying eggs in or on the
bark free (smooth thin "bark"; just undifferentiated epidermis) as
opposed to the thicker multi layered bark followed by Cleridae
looking for a meal of insects, eggs or to lay eggs where the young
will likely find larvae or eggs to eat.
   (Drawing on memory so details may be faulty.) Cut a small Ash
(smooth bark) and leave it where it was but leaning against another
small Ash and within one fine day (sometimes hours) the cut Ash will
have any small round holes and the intact tree will be without holes.
   Thus tree health conditions interaction with insects.

From Doug's observations on the North Mountain, it sounds like the
Beech Leaf-mining Weevil (/Orchestes fagi/) a.k.a. "Evil Weevil", as
coined by folks in Eskasoni, is already out and ready to pounce on
new beech leaves as soon as they unfold. How sad.
The weevil is ramping up to attack the American beech trees again
this spring; what few remain and thrive after the much earlier
introduction of beech bark disease, an invasion from Europe nearly a
century ago.
If it is gathering on the North Mountain, it is also out in the
warmer parts of the Annapolis Valley. I have yet to see this part
of the life cycle, so will head out to search for it this weekend.Â
I am curious about the reported clicking sounds they make. Do you
hear them, Doug? The beech trees are not ready to leaf out yet, so
maybe the weevil will find itself out of sync and starve. That
would be nice.
If I stand out there with a large vacuum cleaner when they are
swarming...? I guess that sounds desperate and futile... So many
of these weevils are likely being moved about on firewood as little
stowaways. I hope our provincial parks will switch to providing
firewood to perhaps keep out infested firewood imports with campers
and keep out the weevil for as long as they can. Valley View Park
will most certainly be devastated, and likely soon. I hope they
have a plan.

On Wednesday, a fine sunny, warm day, our south-facing windows were
covered with little black randomly moving spots, which proved to be
/Orchestes fagi/, Beech leaf-mining weevils. They're waiting
impatiently for the beech leaves to emerge and turn much of our
property into what you describe, Peter -- dead beech trees. They
began the insult last year, and this year I expect a pretty thin
canopy by the end of June. That, plus a change in the way water
accumulates and sticks around more than it used to, causing some
tree dieoff, not to mention much higher and regular winds (and a
neighbour who would rather have a well-groomed yard than those pesky
natural trees) causing blowdown, all adds up to a seriously
challenged bit of forest here on the N. Mountain. Can't wait for the
Emerald Ash Borer!

New subject: Orchestes is out and about
Do I gather that there is no reasonable prospect of re-establishing
Beech here, once /Orchestes/ has finished off all the existing trees? It
seems to me that the weevil must disappear from the province eventually,
once the food plant is gone, but that it could easily come back if
beeches are re-established.
If there were any hope, perhaps some seedlings could be started under
glass now with a view to planting them in suitable habitat with some
sort of mechanical protection from the weevil - a covering of some sort?

An important book will be published Tuesday: Suzanne Simard from UBC is
the author of *Finding the Mother Tree*. She has studied the
interconnectedness of trees, how they help each other through the
underground fungal network, and the importance not only of DIVERSITY, but
of the MOTHER TREE, hence backing up our pleas to retain old growth and
especially older trees, with scientific evidence.
Dr. Simard was interviewed on *Quirks and Quarks* yesterday.
Of course this research has been around for a while and nothing has
changed. Perhaps this book will make a difference if we "propagate" it.
There is a good article here:

".... The trees soon revealed startling secrets. I discovered that they are
in a web of interdependence, linked by a system of underground channels,
where they perceive and connect and relate with an ancient intricacy and
wisdom that can no longer be denied. I conducted hundreds of experiments,
with one discovery leading to the next, and through this quest I uncovered
the lessons of tree-to-tree communication, of the relationships that create
a forest society. The evidence was at first highly controversial, but the
science is now known to be rigorous, peer-reviewed, and widely published.

Thanks for publicizing this, Nancy. Caught the interview and it is well worth a listen.
In my experience, most local and/or traditional knowledge tends to get validated when it
gets subjected to rigorous scientific scrutiny. Local folks have the most comprehensive
knowledge of their circumstances and it’s normal to look for plausible explanations.
The unforgiving real world imposes a need to be objectively critical and another need to
gather lessons as they get delivered and to put them together. The local/traditional
explanations don’t always match what conventional science (if it’s lucky!) discovers,
but more often than not, comes pretty close. It’s prudent to be very cautious before
dismissing perceived truths as superstitions. Where did they come from and why?
The Mi’kmaq concept of two-eyed seeing (“To see from one eye with the strengths of
Indigenous ways of knowing, and to see from the other eye with the strengths of Western
ways of knowing, and to use both of these eyes togetherâ€) makes enormous sense, but
needs to be both appreciated as a universal truth and extended.
Fisheries managers these days, for instance, finally get it. If you ignore the wisdom and
knowledge of local fishers (who, by the way, have the biggest stake in sustainable
management), you are almost certain to make serious mistakes. Ditto if they aren’t
involved in management decisions. Yup, besides sustainability, there are some other
ethical questions at play. …
Thirty-five years ago, I was working directly with rice farmers in Northeast Thailand,
testing the viability of rice-fish culture in their fields. Our field staff officer told
us the farmers would always know best, but would respect our knowledge. I asked him what
the best way of giving advice was.
He said, “By asking questions.â€
A year later, one farmer was hauling out 1 Kg. common carp while his neighbours were
catching fish about a tenth the weight.
He asked me, “Why are my fish so big?†(I’m translating!)
I said, “Your field is big and holds water well. Also, your stocking density is
low.â€
He said, “Nope. I have neighbours who stocked the same way and got smaller fish. But my
water’s saline.â€
He was right; his salinity was barely measurable, in contrast to that of other fields.
Fish physiologists will see that his explanation makes sense.
This from a rice farmer in NE Thailand with a good brain and four years of formal
schooling.
But I digress!

Hi All,
   Many decades ago I visited a remote lake (Dean Chapter I think)
which had become part of a water system for power generation and by good
fortune the water was low so I could see clearly root grafts between
Spruce trees. The roots of every tree were connected to several other
Spruce trees. Root grafting of forest trees has been common knowledge
since erosion or soil slumping has revealed the evidence. But I doubt
very much that root grafting takes place between trees of different
species other than a thin dubious link with microrhizal fungi as the
connection. And the sequence usually is along the following lines-- some
plant root, often but not always woody, pioneers a root channel. When
that root dies and rots a passageway is left for some subsequent root
and when two roots of the same species meet in this tunnel their root
tissues will usually fuse.
   True root grafting is most frequent in soils with compact subsoils
where pioneering a new channel is difficult. But setting that aside, for
trees such as Hemlock which form dense stands with sparse sunlight
reaching the forest floor root grafting is vital because seedlings, the
next generation, depend on root grafts to survive until some nearby
large tree dies and sunlight reaches that dependent. Thus the stump of a
small Hemlock, cut e.g. to enable a survey, will continue to grow in
diameter each year if adjacent large trees are not cut.

Hi All,
Many decades ago I visited a remote lake (Dean Chapter I think) which had become part
of a water system for power generation and by good fortune the water was low so I could
see clearly root grafts between Spruce trees. The roots of every tree were connected to
several other Spruce trees. Root grafting of forest trees has been common knowledge since
erosion or soil slumping has revealed the evidence. But I doubt very much that root
grafting takes place between trees of different species other than a thin dubious link
with microrhizal fungi as the connection. And the sequence usually is along the following
lines-- some plant root, often but not always woody, pioneers a root channel. When that
root dies and rots a passageway is left for some subsequent root and when two roots of the
same species meet in this tunnel their root tissues will usually fuse.
True root grafting is most frequent in soils with compact subsoils where pioneering a
new channel is difficult. But setting that aside, for trees such as Hemlock which form
dense stands with sparse sunlight reaching the forest floor root grafting is vital because
seedlings, the next generation, depend on root grafts to survive until some nearby large
tree dies and sunlight reaches that dependent. Thus the stump of a small Hemlock, cut e.g.
to enable a survey, will continue to grow in diameter each year if adjacent large trees
are not cut.

Hi Mary
   My point was that root grafting between different species was
unlikely. But lack of root grafts does not preclude nutrient sharing
either via microrhizal fungi or other means such as tissue shedding by
source and absorption of released nutrients by other species. Roots are
not stable at the tissue soil interface; root caps get renewed over
time, cortex dies and is shed, feeder roots explore soil, extract
nutrients and die.
   After a soil has drained to field capacity the movement of water to
roots is vanishingly small so plants must continually shed old roots and
extent new ones. But I suspect that if carbon were the tracer, all of
this would be released by the shed source tissue as CO2 and not
incorporated into target tissue. Thus some direct flow of unmetabolized
photosynthate would be indicated.

New subject: Orchestes is out and about
We should allow healthy old beech to decide their fate on their own. We
don't know if the latest invasive pest, Orchestes, will suddenly
subside, slow its spread, or whatever. Even if the pest continues to
spread, the trees you mention may live for another 20 years or more,
which is extremely important for ecosystem services and wildlife.Â
Instructing/demanding LAF to save any large, healthy beech in our public
forests is reasonable. Ask them to flag the trunks before harvest
begins. In fact, if the land is growing tolerant hardwood, such as
beech, the forests are likely pointing toward becoming more tolerant and
heavy removals are entirely inappropriate. Managing shade on the forest
floor is extremely important, and even more so in the context of climate
change. Beech is so very important for wildlife who find less and less
food sources on Crown land where the very best harvest practices are to
take place. The 10 % retention levels are absolutely not acceptable on
lands that are likely to be allocated for ecological forestry. This is
essentially a seed tree release, even-aged forestry. We should be well
past this type of prescription now as we approach nearly 3 years since
Lahey made his recommendations.
For more useful info, check out mother trees. Why mother trees are
crucial for fighting climate change
<cid:part1.622D0A40.BA069A4E@eastlink.ca>.
And here is a case that shows why retaining 10 % canopy is not
recommended as new, Canadian science of how forests work is discovered:
Dispatches from the mother tree forest
<cid:part2.A347B538.956E68FF@eastlink.ca>. This new focus since it is
not just about maintaining old growth but recognizes the functional
advantage these trees provide to other trees within mycorrhizal networks.
It's sad that we all must keep asking for better forestry after a
Natural Resources Strategy (2010) and now Lahey recommendations, and
still there is little change in forestry practices and our last forests
are falling. Logical requests like retaining healthy old trees are
often addressed by industry people using derogatory tones and who taunt
and label us as 'anti-forestry' when we simply want sustainable partial
harvests to meet requirements for biodiversity, wildlife and a better
future for all. Keep up your efforts, Mary.
Regards,
Donna Crossland

Hi Peter and All,
   Ants are very successful and will be around long after the
'superior' animals such as Humans have made earth hostile to Humans and
much more via climate change. I do not recall details but ant strategy
is build around 'hive wisdom' ?
   If an ant sees something which needs to be done it proceeds to do
it without delay. One could do worse than adopt ant mentality; act
according to individual judgment.
   Manipulating the natural world resembles steering a container ship
with one horsehair. But there is, given the safety of numbers, always a
chance that one seed of many will become a tree.
   Over time I took several Plant Ecology courses and came away with
the notion that animals had no effect on plant cover; but they do. One
year I planted about 100 Oak seedlings and gradually all were bitten
off. In 1980 when I bought the North Alton woodlot an Oak about belt
high caught my eye. 42 years later it is still belt high after being
girdled by mice and gnawed off by rabbits numerous times in spite of
1/2" hardware cloth mouse guards.
   But the old saying "Little drops of water, little grains of sand
make the mighty ocean and the pleasant land" also says that one should
think and act like an ant.
   The great menace facing forest cover is climate change; especially
prolonged rainless periods during the growing season and high winds.
   Another menace are those who use forest products every day by using
paper in various forms, live in wooden houses and have wooden furniture
but denounce logging. e.g. the new math-- "What do you think of a man
who will murder 1000 trees a day just to feed his wife and family ?"
   A recent wind (2013 ?) uprooted or broke off nearly all of my large
live Spruce so I considered salvage; horse logging to brow along my
woods roads and conversion to lumber by portable mill so I contacted a
nearby mill owner. He had over 500 large Spruce down and intended to let
them rot in the woods because, as he explained, regulations forbid the
sale of other than certified wood and certification is expensive. Unless
you can use the lumber there is no point in having it sawed out. So I
gave them to a friend to salvage for firewood.
   This is extremely two faced because Fir lumber is now classed with
Spruce. In former times when one could sell Spruce lumber without
certification, even the lowest crook would not have had fir sawed to
lumber because it is brittle and weak. Consequently potential lumber
rots in the woods and more demand is diverted to Crown Land.
