The Emerald Ash Borer:Small Isect; Big Problem
Look closely at a penny. An emerald ash borer (EAB) can t right on top o
one. For its small size, this insect has caused large problems. Follow
the signs rom #1 through #7 to learn more about this exotic insect and its
impact on the environment.
The EAB is responsible or killing millions o ash trees in 15 states(Michigan, Ohio, Indiana, Illinois, Kentucky, Tennessee, Maryland, West
Virginia, Virginia, Iowa, Minnesota, Missouri, New York, Pennsylvania,
and Wisconsin); two Canadian Provinces, and more than two-thirds o the
counties in Ohio. This slender-bodied metallic green beetle arrived in
North America rom Eastern Asia, most likely hidden in wooden material
used in shipping.

A Timelie of Destrctio:The Wor of a Ivasive Species
Look around this area behind the signs and count the ash tree stumps.
Many ash trees needed to be cut at Pearson as a result o the emerald ash
borer. More than 850 trees were cut in 2010 and 2011, while several thou-
sand others have allen or have needed to be removed as hazard trees in
recent years.
2010-2012 Metroparks receives ARRA
grant unding to continue to deal with the
eects o EAB on orest ecosystems. Partnering
with the U.S. Forest Service, the park district
continues removing hazardous ash trees,
controlling invasive species that move in and
planting thousands o replacement trees.
EAB TIMELINE
Before 2002
Unknown in
North America
June 2002
First ash trees killed
by EAB in southeast
Michigan and
Windsor, Ontario
February 2003
EAB discovered in
Ohio, near Toledo
2003-2005
Ohio Department o Agricul-
ture three-part strategic plan
to prevent urther spread o the
destructive insect.
2003 Ohio Department o Agriculture
begins the process o eradicating the
emerald ash borer on Metroparks lands
by cutting ash trees. During this time,
Pearson and parts o the Oak Openings
Preserve were closed to the public.
2005-2008
Metroparks begins mapping dead
hazardous ash trees posing the greatest
saety risk to park visitors and build-
ings. With unding rom Metroparks
general operating levy, these hazardous
ash trees were removed using trained
sta and private contractors.
2008
Metroparks continues to
remove hazardous ash
trees, but limited und-
ing is insufcient to deal
with the magnitude o
the problem.
2009
Metroparks applies or ederal
unding through the American
Recovery and Reinvestment Act.

Carvig Ot TheFtre of Or Forests
Below this sign is an ash log with emerald ash borer tunnels or galleries.
Use your nger to trace the S shaped designs that the worm-like larvae
has created or carved by eeding on the wood into tunnels under the bark.
As the larvae eed underneath the bark, they damage (or destroy) the
phloem, and etch the xylem. The phloem carries the ood made in theleaves down to the rest o the plant including the roots. The xylem moves
water rom the roots upward throughout the canopy.
As the fow is eventually cut o, large canopy trees die quickly. Without
these trees, the amount o light reaching the orest foor increases, which
has impacts on the understory environment. These impacts aect plant
and animal habitats in various ways, as well as oster the spread o invasiveplants, such as garlic mustard, honeysuckle, buckthorn, and thistle.

Impacts to Other Habitats:The Domio Effect
Scoop up a small amount o soil and look closely at it. Soil is a habitat or
many living things. Now look around at other habitats surrounding you.
Count as many spiders, insects and birds as you can in this wooded area.
As ash trees die, impacts occur to our native plant and animal habitats,
sometimes creating a domino eect. In act, large amounts o dead anddying ash trees can change the mineral concentration, acid and moisture
levels o the soil. Since the chemistry o the soil plays an important role in
decomposition and water cycling, ash mortality can aect the nutrient
resource availability or remaining trees.
DID yOu knOWScientists have observed a reduction in ground beetle populations wherethe EAB has been.
At least 282 insects and spiders rely on North American ash trees as a
source o ood and shelter.
Many other species including butterfies, beetles, moths, fies, and true
bugs are aected.

Go native:use Local Trees ad Shrbs
Restoring areas where large ash trees once lived, as well as areas in which
non-native plants have invaded, will be a long process. However,
restoration has already begun at Pearson, Secor and Oak Openings
Metroparks. Thousands o native trees, such as swamp white oak, red oak,
pin oak, sycamore and a Dutch elm disease-resistant orm o the American
elm have already been planted in dierent locations. At Pearson,
approximately 1,000 silky dogwood shrubs have been planted in the areas
where buckthorn (a non-native, invasive shrub) has been removed.
Planting native trees and shrubs makes a positive contribution to our local
ecosystems. Listed below are some reasons why you should consider
adding native trees and shrubs to your yard:Native plants are adapted to the local climate and soil conditions,
making them low maintenance. They require no ertilizing, little watering
and minimal, i any, pesticides.
They provide a nutritious ood source and better habitat or wildlie.
They absorb larger amounts o rain water and can better control erosion.
They contribute to the biodiversity that thrives in Northwest Ohio.

Go native:Some Local Trees ad Shrbs
These northwest Ohio native shrubs, which preer moist soils and oer
great wildlie ood, are excellent choices in areas where ash trees once
lived:
Silky Dogwood (Cornus amomum)
Gray Dogwood (Cornus racemosa)
Common Elderberry(Sambucus canadensis)
Spicebush (Lindera benzoin)
Some northwest Ohio native trees that are appropriate or replacing ash
trees are:
Swamp White Oak(Quercus bicolor)
Northern Pin Oak(Quercus palustris)Northern Red Oak(Quercus rubra)
American Beech (Fagus grandifolia)
Shagbark Hickory(Carya ovata)
Silver Maple (Acer saccharinum)

What Is AHazard Ash Tree?
A hazard ash tree is one located within 100 eet o roads, trails, buildings
or other places where people are likely to be, or where the tree may
damage a valuable asset when it alls. These trees have deects in their
roots, stems, branches and/or trunks that will eventually cause them to die
and all over.
When ash trees die they dry out very quickly and the wood becomes
brittle soon ater. Ater dying rom an emerald ash borer inestation, it
usually only takes 2-5 years or an ash tree to all.
Look beyond this sign and you will see many ash tree stumps located near
the ground. These trees represent a small percentage o all ash trees
that have been cut since 2003. At this park, hazard ash trees are beingremoved to keep Pearson Metropark a sae place.

What do baseball bats, urniture,
oors, bowls, railroad ties, chainsaw
art, frewood and mulch have in
common?
These items can all be made rom the
wood o ash trees inested and killed
by the emerald ash borer (EAB). Byutilizing this wood rom trees that
need to be removed as a result o EAB,
wood waste can be reduced and orest
resources can be conserved.
While traditional orestry practices
have always had a wood utilization
component, salvaging urban treescan also be an option to encourage
sustainability. An example o creative
opportunities inspired by the loss
o millions o ash tree include:
Rising From Ashes: Furniture rom
Lost Trees, presented by The Chicago
Furniture Designers Association;
Cincinnatis Urban Timber Project,
which makes classroom urnitureor schools rom community trees;
and businesses created or expanded
because o the millions o inested
ash trees which lead to potential
wood utilization opportunities.

Pearson Metropark is just one o many areas to be aected by the emerald ash
borer in recent years. The wet, swampy woodland ecosystem at this park
provides avorable habitat or ash trees, on which this invasive species eeds.
To learn more about the emerald ash borer and its eects on the environment,take a ew minutes to visit the series o interesting, educational signs along
this trail.
Funding or this demonstration trail was made available through the eorts
o Congresswoman Marcy Kaptur and the USDA Forest Service to support the
Western Lake Erie Basin Emerald Ash Borer Community and WoodlandsAssistance Program administered by the Ohio Department o Natural Resources
- Division o Forestry.
