Default Do Woodpeckers Systematically Destroy Bradford Pears?

Hi Folks,

While doing yardwork yesterday, I happened to notice a strange pattern
on the trunk of the large Bradford Pear tree we have in our front yard.
This tree is about 12 years old, less than a foot through at the
thickest part.

Anyway, what I noticed was that there were literally thousands of holes
through the bark of the tree, evenly spaced in circles all the way
around the trunk. They start at ankle height and go higher than my
head, where the lowest branches start.

They're about the size of a pencil eraser and go in maybe twice as deep.
It looked as if there wasn't even a square inch without this pattern
of holes in it over the entire main trunk.

The tree doesn't appear to be sick otherwise. It blooms completely
every year - in fact it's in bloom right now. Up until the big ice
storm in December it hadn't lost any branches, other than the low ones
I've trimmed. During the ice storm it lost a few large branches from
higher up, but it still looks full and healthy.

I'm not sure the damage was done by a woodpecker because I haven't seen
it happening, but the regular pattern makes me think that's what it is.
It's taken less than a year because I look at this tree fairly often,
and this is the first I've noticed it. When I was clearing away the
broken branches in December I didn't see them.

I'm wondering if the tree is likely to die from all this damage, and if
anyone can confirm that there are neurotic, single-track minded
woodpeckers that do this!

Thanks,

-dreq

Derek, could it be borer beetles? My understanding of woodpecker damage is
that they only damage trees that already have insects in the bark.

FWIW, I noticed a hole in the CCA- treated lumber on the underside of our
deck a few years back. It was about the size of a pencil, and I squirted it
with wasp and hornet killer. Yup- soon there were several dead wasps laying
on the ground under the hole. I had not been aware that they would bore
into CCA-treated lumber, but they sure as heck did.

Try spraying a hole or two with bug killer and see if it produces anything.
Hopefully, it won't harm the tree. From what we saw after the ice storm,
your Bradford Pear must be one of the few surviving ones in the Triangle.

derek it is the sap sucker bird who is making the holes

The wood peckers may be going in afterwards to eat the bugs going in
afterwards

Yes the holes attract insects that will also bore into the tree - if there
are no insects the tree will not die directly from the holes.

You might as well hang up dead fish outside with the nasty smell that Bradfords produce. Why
bother planting these trees when you could have much hardier and reliable native trees?

(yeah yeah, pretty looking, but godDAMN that smell)

I thought of Bradford Pears as one of the prettiest landscape trees for
their color, density and symmetry. When blooming, they're even prettier.
Sadly, it gets too hot out her in Las Vegas for them, even when watered
well.

I never noticed any odor coming from our Bradfords. I know that one of the
real "stinkers" is the Hawthorne, which also has white blooms. I'd put the
Hawthorne up there toward the top of foul smelling plants, but only when
blooming. For anyone wishing to experience the smell of a Hawthorne, drop
by the News and Observer's downtown plant in mid Spring and smell the ones
planted out by the street.

I don't plant them, I just enjoy them. Let others clean up after the ice
storms. But no, I've never noticed the smell either and we walk around our
neighborhood daily.

BTW, anyone know what shrub/tree has the ethereal grape smell? I get whiffs
occasionally, but can never localize it. There are a couple of places on
US1 near Crossroads and a couple spots in our neighborhood.

Could it be kudzu? It has that "artificial grape" smell when blooming.

I believe that's it! Someone else described it as grape Koolaide.

Actually, I've seen both sapsuckers and woodpeckers do quite a job on
Bradford pears. Those Bradford pears were hugely popular for awhile,
and many a nurseryman made a mint off those crummy trees. They are
crummy because: They attract a lot of insects and bugs and are prone
to disease and die-off.. They have very weak wood and often split
apart under a good wind or stress, and they die quickly.. usually in
less than 30 years.
Of course, you can spray the heck out of them and keep the bugs away
but if you were going to do that why not plant a tree that has fruit
you can EAT?

Derek,

The holes you describe were made by a sapsucker
http://www.ancientforest.org/sapsucker.jpg Although sapsuckers are members
of the woodpecker family, they feed on living trees, because it's the sap
(and the insects it attracts) that is their target. To the best of my
knowledge, sapsuckers don't usually kill the trees they're using -- after
all, if the tree died, there would be no more sap!

[in response to a subsequent post] Interestingly, when I walked near my
blooming Bradford Pear yesterday, I would have sworn that it had a very
subtle, pleasant odor -- although I had not noticed it in previous years.
My tree survived the ice storm intact, surprisingly, so I did not need to
worry about trimming it. It also seems to be popular with the birds in my
yard, who *seemed* to be eating the buds, but were probably after insects &
caterpillars in the tree. And, frankly, since the tree is a favored perch
of the bluebirds nesting in the box next to it, there's no way I'd cut it
down!

Not neccessarily. By the same logic, humans wouldn't usually kill the cows
we use

Awwwwww darn it ya'll party poopers. I wanted to be the first to
tell Dreq that it's the Yellow bellied sapsucker (Dreq, we just
had a conversation about them here a month ago, that's why I
jest) that makes those holes. From what I have heard here,
cicadas make similar marks on trees, just not as many. I don't
have Bradfords (tg) so I can't speak as to how they will hold up.
The sapsuckers are on my holly trees. For the 3 years I've been
here, I've seen no symptoms of stress.

Is it *possible* to stress hollies? They seem to thrive no mater what
insults are delivered to them.

Our holly trees thrive in drought, freezes, blizzards, and came through
two hurricanes unscathed. The genetic engineers ought to be looking at
them if they want to create crops that survive anything.
