Emerald Ash Borer Arrives!!!
This year’s generally
comfortable summer weather has resulted in the discovery of a much feared
and potentially landscape changing beetle called the Emerald Ash Borer (E.A.B.).
Government agencies and local tree experts have searched for signs of the
E.A.B. on Illinois’ash trees for the past 3 years. Since first being
detected on an ash tree in Michigan in 2002, the beetle has killed more than
15 million ash trees in that state alone. Experts believe beetles actually
infested trees in Michigan anywhere from 3 to 5 years before 2002. The
borers are believed to have been brought to Illinois through firewood or
nursery stock. The transportation of firewood and nursery stock across state
lines from Michigan or Indiana is illegal.
Currently, the Morton
Arboretum and the Illinois Department of Agriculture are thoroughly
inspecting all ash trees within a square mile radius of infected trees. Once
the scope of the spread of E.A.B. is established, quarantine areas will be
set up around the infested trees. Currently there are
no treatments or 100% effective pesticides that
completely kill and stop the spread of the borer. Ash trees infested with
the borer will inevitably die.
There are approximately 131
million ash trees in Illinois. It’s estimated that 1 out of every 5 trees in
the Chicagoland area are ash trees. There are over 1000 ash trees growing on
Village owned property alone. Private property and Forest Preserve figures
could easily push the number of ash trees in our community to over 5,000.
The arrival of E.A.B. to Palos Park would have a tremendous impact to our
own and surrounding properties.
With the arrival of
the E.A.B. and continuous spread of such diseases as “Oak Wilt” and
“Dutch-Elm” disease, some of our areas main tree species are in jeopardy. We
recommend that residents plant not more than 10% of one species on their
properties. Having many different tree species in your yard would eliminate
a major impact to your landscape in the event of disease to one species.
Residents should consult their local nursery or tree service for information
on correctly diversifying their landscape. Any questions or concerns about
the E.A.B. should be directed to the
Department of Agriculture at 847-294-4343 or to
hotline at 1-866-EAB-4512.
There are also free informational brochures on the E.A.B. at the Kaptur
