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 8,300
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
health.

Fungal Disease on Trees:
In 2010, we have seen a high level fungal leaf diseases with all the
spring rains and warmer weather. Typically most leaf disease are
minor and do not impact the tree or shrub. The leaves look
unaesthetic and make the tree or shrub look unhealthy. The tree
or shrub will push a new flush of leaves in mid July or early August to
replace the diseased leaves. Click

utility compatible trees will not grow taller than 25 feet and will not
require any pruning for the electric power lines.

Bagworms Sited in BG:
Bagworms are hatching and larval are in Instar 1 about 1/4 inch long
in the city. Bagworms can defoliate and cause tree mortality in
one season. Click here on more
information on how to control bagworm.

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

There is an Oyster Shell Scale insect outbreak in Bowling Green on
Freeman maple trees, elms, and honey locust. Small trees that are
4 inches in diameter or smaller are attacked and killed from the scale
insect. Click here for

Improper pruning of a private tree. Note the tree was stubbed off
and does not have adequate foliage to maintain the tree. The tree
will go into decline and eventually will die back. The tree is
predisposed to insect and disease problems.

The Ohio State University EAB Research Team on June 5,
2009.
The Ohio State University (OSU) with cooperation from the City of

determine the genetics that make ash trees from Asia and Europe
resistant to Emerald Ash Borer. Click

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
3 (South of W. Wooster and East of S. Main) in 2009.

Picture above shows the S-shaped galleries left by the
Emerald Ash Borer larvae.
Emerald Ash Borer (EAB) spreads throughout the City Of
Bowling Green.
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.
City Tree
Planting in Green Spaces:
Our Tree City USA Program has planted over 1700 trees from
May 2004 through May 2009. 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 2010:
Our internal City tree crews will be working on pruning large
trees primarily on the east side of the City of Bowling Green in Ward 1
& Ward 2, City Park, and the Bowling Green Country Club. The
crews will be pruning out dead and diseased branches,
broken/crossing branches or branches that extend over the street or
sidewalks.
Priority Removal Trees 2010:
Our internal City tree crews will coordinate on removing
priority trees on the east side of the City of Bowling Green in Ward 1
& Ward 2, 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
category.
Train Pruning of Small Trees 2010:



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 tree.
The Urban and Community Forestry staff will be working in
the new Subdivisions from May 2009 to August 2009. 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.
