Description
Park Maintenance's Paul Edwardson explains it is important not to work on Ash trees during the summer.
B
I
think
an
important
thing
to
get
across
to
people
is
that
it's
very
different
than
dutch
elm
disease
or
oak
wilt
disease,
which
unfortunately
we're
familiar
with
from
many
years
of
dealing
with
it.
Ash
trees
is
a
tree
that
we
really
want
to
leave
alone
during
the
active
period,
which
is
may
june
july
and
august.
In
other
words,
we
don't
want
to
be
trimming
them.
We
don't
want
to
be
removing
them
unless
we
absolutely
have
to,
and
then,
if
we
do,
that,
we
want
to
do
it
in
the
proper
way.
B
A
And
that's
a
different
mentality
for
sure
than
like
you
describe
those
other
diseases,
really
an
important
change
to
kind
of
get
through
all
of
our
heads
people
who
aren't
as
familiar
with
it,
I
suppose,
to
get
that
out
of
there
now
there's
a
quarantine
in
effect
for
the
metro
area.
Maybe
that's
the
next
place
we
next
step
we
talk
about
is
the
fact
that
it's,
it's
not
only
a
bad
idea,
but
it's
against
against
the
law
really
to
take
those
trees
out
of
hennepin
or
ramsey
county
right.
B
Once
they
are
in
the
quarantine
area,
they
basically
have
to
stay
in
the
quarantine
area
unless
they
have
been
dealt
with
according
to
the
requirements
of
the
minnesota
department
of
agriculture
as
far
as
disposal
and
those
kinds
of
things
so
really
the
safest
and
and
the
easiest
way
to
explain
it
is
once
it's
in
the
quarantine
area.
It
needs
to
stay
in
it.
It
can
move
around
in
the
quarantine
area,
healthy
wood.
We
certainly
don't
want
to
move
diseased
wood
around,
but
it
can't
leave
the
the
quarantine
area.
Sure.
A
And
it's,
I
think,
important.
You
were
explaining
that
the
emerald
ash
borer
can
actually
jump
out
of
the
bed
of
your
pickup
truck
if
you're
moving
diseased
wood
around
it.
It's
easy
for
this
bug
to
really
move
and
spread,
and
it's
not
something
you're
going
to
notice
when
it
leaves
leaves
your
vehicle
or
leaves
your
property
or
leaves
anything
yeah.
B
It
certainly
can
be
transported
by
us
on
vehicles
on
firewood
other
woods.
It
flies
too,
so
it
can
move
on
its
own.
So
what
we
want
to
do
by
not
working
with
trimming
or
removing
ash
trees
in
the
summer
is
we
don't
want
to
disturb
those
trees
that
might
have
the
emerald
ash
borer
in
them?
B
Leave
it
there
for
a
habitat,
and
then,
when
the
the
critical
period
is
over
in
the
fall
and
the
winter,
then
we
can
more
safely
deal
with
that
wood
transport
it
get
rid
of
it
so,
the
next
year
we've
we've
dealt
with
it,
the
best
that
we
possibly
can
and
we've
done
everything
we
can
to
try
to
reduce
or
eliminate
the
spread
of
it
sure.
B
Unfortunately,
there
is
nothing
we
can
do
to
stop
it,
we're
hoping
and
and
we're
taking
our
cues
here
in
the
city
from
the
department
of
agriculture,
but
the
hope
is
that
we
can
slow
it
down
and
control
its
spread,
but
at
this
time
there
really
isn't
anything
we
can
do
to
stop
it.
I
think
one
of
the
very
revealing
facts
is
that,
30
or
40
years
ago,
when
dutch
elm
disease
hit,
there
were
an
estimated
150
or
so
million
elm
trees
in
minnesota.
A
Course,
here
in
bloomington
and
also
in
the
metro
area,
we
love
our
trees
and
our
parks
and
and
whether
the
trees
are
on
private
property
or
public.
We
want
to
keep
them
alive.
Let's
talk
about
the
the
bug
itself,
it's
essentially
in
the
it's
a
very
shallow
in
the
in
the
bark
of
the
tree.
It's
right
in
the
hardwood
of
the
tree.
Maybe
you
can
explain:
we've
seen
the
billboards
they
were
out
last
year,
but
it's
another
reminder
of
just
what
this
bug
actually
does
to
the
trees.
B
It's
it's
fairly
small
in
size.
It's
only
about
half
the
width
of
a
penny.
It's
it's
generally,
quite
emerald,
green,
that's
where
it
gets
its
name,
but
when
it
it
goes
through
a
metamorphosis
as
insects
do
and
it
goes
into
the
tree.
It
goes
through
the
bark
and
into
the
hardwood
of
the
tree,
and
so
it's
approximately
an
inch
in
depth
and
that's
where
it
starts
killing
the
tree.
B
It
starts
feeding
on
the
tree
and
and
creates
a
situation
where
the
tree
cannot
move
water
and
nutrients
through
the
tree
and
it
actually
kind
of
starves
it
and
chokes
it.
So
you
won't
see
it
on
the
outside
the
tree
very
often,
and
even
the
little
d
holes,
which
are
one
of
the
characteristics
when
the
bug
comes
out
of
the
tree.
A
And
that's
what
you
were
saying
is
we
talked
about
this
the
end
of
the
year
last
year
that
it's
it's
a
really
hard
disease
to
to
keep
track
of,
because
it
might
not
show
signs
for
five
years.
A
tree
could
be
infected
for
five
years
before
you
really
know
know
that
there's
a
problem,
but
but
what?
If
residents
are
concerned
that
maybe
a
tree
is,
is
infected
or
diseased?
Who,
who
can
they
call
or
what
should
they
be
looking
for,
with
at
least
with
emerald
ash
borer.
B
Well,
I
think
the
things
that
you
want
to
look
for
in
your
tree
is
certainly
declining
health.
That's
that
can
be
one
of
the
symptoms
of
of
a
number
of
diseases
and
ash
trees,
unfortunately,
are
not
only
affected
by
the
emerald
ash
borer.
There
are
three
or
four
native
ash
borers
that
also
attack
and
do
some
of
the
same
kinds
of
things.
Although
they
don't
kill
the
ash
tree,
but
they
certainly
after
a
time,
can
help
reduce
its
vigor.
So
if
you've
got
an
ash
tree,
that's
looking
a
little
peaked.
B
That
could
be
one
of
the
things
if
you've
got
woodpeckers
packing
on
the
tree
and
you
can
see
woodpecker
damage.
That
certainly
is
a
another
possible
characteristic
or
bark
splits.
I
mean
noticeable
splits
in
the
bark
if
those
kinds
of
things
are
out
there
on
your
ash,
trees
or
ash
trees
in
the
city,
we
would
want
people
to
call
our
public
works
department
and-
and
let
us
know
that,
give
us
a
location
and
we'll
do
up
a
work
order
and
have
one
of
our
state
certified
tree
inspectors
come
out
and
and
take
a
look.
B
Can
certainly
give
us
a
call,
also
our
city
web
page.
We
are
constantly
updating
information
and,
as
a
matter
of
fact,
just
today
we
got
the
the
newest
and
the
greatest
and
the
most
current
information
from
the
department
of
agriculture
and
so
we'll
be
putting
that
information
on
our
web
page
and
also
links
to
the
department
of
agriculture,
the
u.s
department
of
agriculture,
the
department
of
natural
resources,
so
there'll
be
a
lot
of
information
available,
both
specifically
on
the
city
webpage
and
links
that
we
provide
sure.
Thank.
