I
think
it's
it's
moving
pretty
much
on
track
with
what
people
were
expecting
in
a
lot
of
different
cases
in
different
states.
There'd
be
one
isolated,
find
and
then
you'd
find
nothing
for
a
while
and
then
another
one
and
then
sort
of
fines
are
sort
of
explode
from
that
and
that's
sort
of
what
we
found
in
Iowa
as
well.
It
just
stayed
in
northeast
Iowa
for
a
really
long
time,
and
then
they
found
another
find,
and
then
people
started
finding
it
all
over
Eastern,
Iowa
and
out
sort
of
moving
west.
So.
A
B
So
emerald
ash
borer
came
to
the
United
States
from
Asia
and
it
was
found
in
Detroit
and
it's
a
small
metallic
beetle
that
favors
ash
trees,
but
the
beetle
itself
isn't
what
harms
the
tree.
It
lays
eggs
on
the
bark
and
when
they
hatch
larvae
burrow
into
the
tree,
and
as
these
this
larva
eats
through
the
tree
and
burrows
through
it.
It
stops
the
tree
from
being
able
to
transfer
nutrients
up
and
down
the
tree
and
stopping
that
nutrient
transfer
is
what
slowly
kills
the
tree.
So.
A
B
No
stopping
the
progression
of
emerald
ash
borer.
They
tried
really
hard
when
they
first
discovered
to
try
and
eradicate
it
by
removing
all
the
ash
trees
from
a
certain
radius
around
the
place
where
they
found
it.
But
they
weren't
able
to
really
do
that
so
now,
just
managing
it
and
trying
to
slow
it
down
and
then
trying
to
recover
from
it
and.
A
B
B
There
there's
several
different
things.
That
really
will
let
you
know
if
your
tree
has
a
problem
with
that
you
can
see
exit
holes
are
a
big
one.
That's
how
you
know
their
larvae
in
there
and
that's
when
the
larvae
has
matured
into
an
adult
in
leaves
emerald
ash
borer
leaves
a
d-shaped
because
it's
a
flat-headed
bore,
so
it
has
a
round
belly
and
a
flat
back,
so
when
it
leaves
it
leaves
a
d
shape.
Also
you'll
start
to
see
die
back
from
the
top
of
the
tree.
B
There
won't
be
leaves
on
certain
branches
and
will
start
coming
back
as
it
loses
those
nutrients.
You
also
might
see
something
we've
found
very
indicative
in
Iowa,
is
woodpecker
flaking,
so
these
woodpeckers
are
looking
for
the
larvae
in
the
tree
and
to
try
and
find
them.
They
flick
off
bark
to
try
and
get
closer.
So
as
you
look
up
this
tree,
you
see
white
flecks
along
these
branches
and
that's
been
a
pretty
big
sign.
So.
B
That's
that's
always
a
pretty
big
sign.
There
are
a
couple
native
bores
that
will
leave
that
D
shaped
too.
So,
even
when
you
find
that
the
only
way
to
know
for
sure
is
to
remove
branches,
and
then
you
peel
back
the
bark
and
you
look
for
those
the
galleries
that
the
larvae
ate
through
the
tree
there's
this
s-shaped.
They
generally
make.
So
you
look
for
that
and
you
try
and
find
it.
B
A
B
So,
a
couple
years
ago,
the
city
of
Ames
hired
some
interns
from
Iowa
State
to
do
an
inventory
of
all
the
city-owned
trees.
So
they
went
around
with
iPads
and
they
took
all
of
the
city
on
trees
that
are
in
parks
or
city-owned
property,
or
the
rights
of
way
between
like
the
street
and
the
sidewalk.
So
they
said
what
kind
of
tree
it
is
how
it
is
general
health
conditions
and
stuff
like
that.
B
A
B
A
B
Ash
is
pretty
easy
to
identify
it
some
of
the
easier
ones.
What
really
sets
it
apart
is
that
it
has
opposite
branching,
so
trees
either
have
opposite
branching
or
alternate
an
opposite
means.
The
branches
are
growing
right
across
from
each
other
and
alternate
means
they're
offset,
and
there
are
only
a
couple:
trees
that
have
opposite
branching
and
the
main
ones
are
either
ash
or
maple.
So
if
it's
not
a
maple
tree,
it's
an
ash.
B
What
another
thing
to
look
for
in
an
ash
is
that
it
has
compound
leaves
instead
of
a
simple
leaf,
and
that
means
the
entire
leaf
has
a
stem,
and
then
these
leaflets
that
come
off
of
it,
so
that
entire
thing
is
the
leaf,
not
those
small
ones.
So,
when
you're,
seeing
that
opposite
branching
and
those
compound
leaves
those
leaflets,
that's
pretty
much
an
ash,
it
also
has
sort
of
a
quilted
bark
look
and
that's
also
a
good
way
to
look
at
it.
So.
B
Since
eb's
now
been
confirmed
as
close
as
Boone
I
think
you
might
want
to
consider
treatments
for
your
trees.
These
treatments
only
work
when
the
tree
is
still
very
healthy.
After
its
declined
more
than
like
twenty
percent,
the
treatment
might
not
be
able
to
save
the
tree
from
their
mole
dashboard,
so
those
are
chemical
treatments
that
inject
into
the
tree.
That's
the
most
effective
kind,
so.
B
In
any
sort
of
kind
of
quick,
I
disasters,
not
the
right
word,
but
when
this
sort
of
big
thing
happens
all
at
once
in
a
place,
there
might
be
some
people
coming
in
and
trying
to
make
money
off
of
people
like
that.
So
it's
important
that
when
you
do
hire
someone
to
do
this,
you
make
sure
they
have
a
certified
arborist
on
staff
and
the
city
of
Ames
on
their
website
has
a
tree
surgeons,
page
with
people
who
have
registered
with
the
city
of
Ames
and
it'll.
B
B
So,
even
if
you
do
decide
you
want
to
treat
your
tree
chemically,
you
need
to
do
that
every
year,
every
other
year,
or
maybe
every
three
years,
but
for
the
life
of
the
tree.
So
you
have
to
incur
that
cost
over
and
over
and
over
again
what
some
people
have
been
considering
is
planting
a
new
tree
in
their
yard
and
treating
their
old
tree
until
their
new
tree
gets
more
established
and
starts
providing
those
benefits
that
their
old
tree
was
providing
and
then
removing
the
old
tree
and
stopping
treating
it.
So.
B
What
they've
been
doing
is
that
there
have
been
programs
where
people
have
set
aside
ash
seed
and
they've
put
those
in
vaults
to
keep
them
around,
for,
if
maybe
emerald
ash
borer
goes
through
and
it's
gone,
we'll
be
able
to
re
propagate
ash
and
bring
them
back
out.
There's
also
a
chance
that
there's
some
ash,
maybe
in
woodlands,
kind
of
hiding
that
are
naturally
resistant
and
maybe
we'll
be
able
to
breed
those
naturally
resistant
trees,
but
that'll
sort
of
be
hard
to
say
until
this
first
wave
of
it
going
through
the
country's
finished.
So.
A
Really,
the
best
recommendation
have
a
plan,
decide
what
you
want
to
do
if
you
have,
depending
on
the
health
and
age
of
your
tree,
there's
some
decisions
that
need
to
be
made
again.
You
mentioned
our
website.
We
have
the
list
of
tree
surgeons
on
the
website.
Are
there
other
resources
that
people
could
look
towards
the.
B
A
A
If
you'd,
like
more
information
about
tree
surgeons,
names,
remember
that
list
is
on
our
website
at
city
of
ames
org.
Also,
some
things
to
think
about.
Remember
that
city
hall
and
most
city
offices
will
be
closed
for
on
for
Labor
Day
on
Monday,
September.
Third,
and
also
remember
the
Ames
public
library
will
be
reopening
its
doors
at
the
renewed
library
at
515
Douglas
on
Sunday
September
14th.
Well,
that's
our
show
thanks
for
watching
and
tune
in
next
week
for
this
week
in
Ames.
