    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.

    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.

    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

    Western Lake Erie Basin Emerald Ash Borer Community and WoodlandsAssistance Program administered by the Ohio Department o Natural Resources
