The mission of the Bowling Green Arborist is to provide a high
quality urban forestry program to the community, in conjunction with
expert advice on private tree care. The Arborist cares for the City
trees within the road right-of-way, as well as regular line clearance
tree trimming program for safe and reliable electricity.
The City of Bowling Green urban forest includes more than 8,800
trees in the public right-of-way, public parks, and green spaces. A
healthy and safe urban forest includes: wildlife diversity, higher
property values, air and water quality, storm water management, energy
savings from summer and winter extremes, and quality of human

Thousand Cankers Disease of Walnuts
Thousand Cankers Disease (TCD) of walnut has been confirmed in
Butler County, Ohio. The disease is caused by a fungus
(Geosmithia sp.) that is carried from tree to tree by the
Walnut Twig Beetle (Pityophthorus juglandis); a type of bark
beetle. Here is a quote from the news release from the Ohio
Department of Agriculture (ODA):
“Walnut Twig Beetle was first confirmed in Ohio in late 2012
in traps set by Ohio Department of Natural Resources Division of
Forestry officials in Butler County. Additionally, scientists
from the Ohio Plant Diagnostic Network, a cooperative partnership
between ODA and The Ohio State University, recently isolated the TCD
fungus from walnut branch samples from the Butler County area, marking
the first time TCD has been confirmed in Ohio.”
Keep a sharp eye out for the signs and symptoms of TCD on
walnut: chlorotic and wilted leaves, twig and branch dieback,
thinning canopy, and epicormic growth. Unfortunately, the current
leaf chlorosis and leaf drop from walnut anthracnose may confuse the
issue. We will have a report on TCD in this week’s Buckeye Yard
and Garden Line (BYGL); the online version ( http://bygl.osu.edu/ ) will
Please report suspicious walnut trees to the ODA at 855‐252‐6450 or

“We are a relatively small urban forestry program, but we have
proved you can do a lot with drive, passion and the support of your
community,” said David Bienemann, the first municipal arborist for the
city of Bowling Green, Ohio.
Spruce Trees Impacted by Environmental, Insects, and Diseases:
Spruce trees do not like to be planted wet, clay soils. The
spruce trees become stressed and start to decline. Then insect
pests are attracted to the stressed tree. The insect pest brings
in the disease such as cytospora canker or phomopsis canker.

Template for Assessing Climate Change Impacts and Management
The Template for Assessing Climate Change Impacts and
Management Options (TACCIMO)
is a Web-based tool that
provides land owners, managers, and planners with the most current
climate change science available. Developed by EFETAC
researchers in partnership with USDA Forest Service Southern
Regional Planning, Land and Resource Management, and Cooperative
Forestry, the TACCIMO tool:
- compiles climate change projections, literature-based impacts and
management options, and Forest Service land and resource management
plans in an online database;
- synthesizes these inputs based on user-defined criteria;
- creates an optional customized report to aid forest planning and
Information generated by TACCIMO can satisfy a range of needs for
a variety of users including federal planners and managers as well
as state, private, and cooperative forestry stakeholders.

Landscaping Options for Underground Electric
The City of Bowling Green Electric Division requires 3 feet of space
on the sides and the rear of the padmount transformer and a minimum of
8 feet in front of the transformer for safe operations of
service. Planting landscape material, rocks, retaining walls or
putting in fences to hide the "green box" is a safety issue for both
City Electric crews and the land owner. Please click here to see a guide for
landscaping in the vicinity of a padmount transformer.
REMAINING COUNTIES ADDED TO OHIO EMERALD ASH BORER
Following recent confirmations of emerald ash borer (EAB) in the
Wayne National Forest, and taking into account the infestations in
surrounding states, the Ohio Department of Agriculture (ODA) expanded
the state's EAB quarantine to include all Ohio's 88 counties on
Thursday, September 8, 2010.
Despite the fact that quarantining the whole state will allow for
ease of movement of ash materials and hardwood firewood, it is
recommended that Ohioans continue to exercise caution when moving these
materials. "Limiting firewood movement helps the state protect
against the artificial spread of many pests in addition to emerald ash
borer, including gypsy moth and Asian longhorned beetle," said Ohio
Agriculture Director Robert Boggs. "The department strongly urges
Ohioans to continue buying firewood locally." The federal quarantine,
enforced by the US Department of Agriculture, remains in effect. This
quarantine makes it illegal to transport ash trees, parts of ash trees
and all hardwood firewood out of the state of Ohio. There is
still interest, and potentially more so with the expanded quarantine,
to continue to monitor and track this insect pest. To accomplish this,
ODA will continue to accept specimens for confirmation. As specimens
are confirmed as EAB, maps will be updated. All samples must be
accompanied with a Specimen of Determination form that can be found on
the ODA website, or by calling 888-OHIO-EAB. For
information on the EAB, check out OSU's EAB website at
http://ashalert.osu.edu . Additional information on the expanded
quarantine or regulations can be found at http://www.agri.ohio.gov .

Emerald Ash Borer (EAB) has reached epidemic populations levels in the
City of Bowling Green. Businesses and Home Owners should to have
their private ash trees inspected by the Municipal Arborist or a
Professional Tree Service to determine the options available for
managing EAB. Click here for latest research on EAB insecticide
treatments. Click here to determine the percentage of canopy

maintenance pruning (Linden on left and Locust on right).
Routine Maintenance Pruning
Routine Maintenance trees are defined as trees recommended for
horticultural pruning to correct structural problems or growth patterns
which could eventually obstruct traffic, pedestrians walking
on sidewalks, interfere with utility lines, or buildings.
Trees in this category are large enough to require bucket truck
access or manual climbing. Our crews prune a maximum
of 25% of the canopy from the trees. We will move into Ward
4 (North of W. Wooster and West of N. Main) in 2014.
Picture above shows the S-shaped galleries left by the
Emerald Ash Borer larvae.
Emerald Ash Borer (EAB) spreads throughout the City Of
The numbers of trees identified as infested with Emerald Ash Borer
has increased significantly throughout Bowling Green. The City is
taking pro-active measures to deal with EAB and now is encouraging
citizens with ash trees to consider future actions for their
trees. Bowling Green residents and businesses are encouraged
to consider options for managing ash trees. Two primary
options available: removal/replacement or insecticide treatment.
Removal and replacement prior to infestation is the most cost effective
option. Dead and dying frequently cost 2-3 times more to remove
than live trees due to unpredictable nature of dead wood. The
risks to surrounding structures and to the lives of qualified arborists
who remove these hazardous trees is a major factor in
the cost. For tips on hiring an arborist, visit http://www.treesaregood.org/
for a consumer guide How to Hire and Arborist.
Systemic insecticides may be an option to prolong the life of highly
valued ash trees prior to infestation. The Ohio State University
Extension Office has developed specific recommendations on
insecticides. Click here for more information. While
insecticide products are not 100% effective and are preventative
measures, it is an EAB management option.
ODOT Certified Training
The Public Works Division staff, Electric Division staff, and Parks
& Recreation Department staff attended safety training in aerial
bucket truck operations, chainsaw operations, and chipper
operations. Our goal is to provide the best service to the
residents of Bowling Green and our urban forest.
Planting in Green Spaces:
Our Tree City USA Program has planted over 3156 trees from May
2004 through May 2013. The goal is to plant the "Right Tree in
the Right Place" by selecting trees that fit the planting site based on
soil type, drainage, infrastructure (power lines, gas lines, water
& sewer lines), visibility triangle and long-term capital
improvement projects. The City Arborist coordinates with multiple
City Departments to include the preservation of trees or tree
replacement programs to maintain the canopy effect. All new
subdivisions and new business plans are now reviewed by the City
Arborist to offer recommendations on future tree plantings and
landscape design plans.
Priority Pruning of Large Trees 2014:
Our internal City tree crews will be working on pruning large
trees primarily on the west side of the City of Bowling Green in Ward

branches or branches that extend over the street or
Priority Removal Trees 2014:
Our internal City tree crews will coordinate on removing
priority trees on the west side of the City of Bowling Green in Ward 3
& Ward 4, City Park, and Bowling Green Country Club. Priority
trees are defined as trees that are dead or have one or
more defects that cannot be maintained by pruning. The
majority of trees in this category have a large of percentage of
dead crown and potential safety hazards. Large dead and
dying/diseased tree are high liability risk are included in this
Train Pruning of Small Trees 2014:
Picture 1 (Top) shows proper train pruning of smaller
trees. Picture 2 (Center) we are pruning 25%-30% of lower
branches. Picture 3 (Bottom) shows our City tree crew training
The Urban and Community Forestry staff will be working in
the new Subdivisions from May 2014 to August 2014. The crews
are pruning smaller trees to remove dead branches, crossing
branches, and branches that extend over the street or
sidewalk areas. The objective is to train the tree
to provide safe clearance for motor vehicles, signs and
pedestrians. The pruning corrects the structure and form of the
young trees to help grow healthy and strong as they mature.
