What is the Emerald Ash Borer

The Emerald Ash

Borer is a small

metallic green

beetle that is

known to kill all

species of ash

trees.

Beetle larva eat the living tissue (cambium)

between the bark and the wood, effectively

girdling the tree.

What does this mean?

• 1 in 14 trees in New York is an ash tree

• Thousands of ash line our trees, shade our parks

and fill our public spaces.

• Thousands more dot our home landscapes

• Millions can be found in our woodlots and along our

rivers and streams.

EAB puts all of these trees in

danger.

Concerns

Ash trees break down quickly once they die,

potentially dropping large limbs in public

areas or on personal property.

• Trees are costly

to treat and remove

Community Questions

Are your ash trees

identified?

Who owns them?

Whose responsibility is

it to treat or remove

potentially risky ash

trees?

Will you treat or

remove your

community’s trees?

Can you afford to manage

them?

Can you afford not to?

Community Preparedness Plan

Daniel Herms, The Ohio State University, Bugwood.org

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Why make a plan?

• To identify the:

• PEOPLE

• RESOURCES

• MONEY

available to help manage the effects of EAB

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Plan Elements

• Background Elements - describe your community and

EAB’s potential impact

• Management Plan - outline your specific management

actions for specific trees

• Education Plan - identify stakeholders, how they relate

to EAB and their educational needs

• Budget - what will it cost and how it will be paid for.

• Contacts - who is responsible for the plan

• Sources of Information – EAB references for planners

and stakeholders

Preparing for the Emerald Ash Borer

EAB Plan- Background

• EAB History and Biology

• Scope of NY and Local EAB problem

• Number of Community Ash Trees

• Economic Conditions related to ash trees

– Mills, ash product producers, etc.

• Plan Purpose

Preparing for the Emerald Ash Borer

http://nyis.info/eab


EAB Plan: Management- Inventory

• IDENTIFY public (and private) ash trees

– Do you have an inventory?

– Inventory options

• Complete community tree inventory

• Community ash trees

• Community and all private ash trees

• Community and private ash trees that can affect community

property

– Who will conduct an inventory?

• Determine their potential RISK

Preparing for the Emerald Ash Borer

http://nyis.info/eab


EAB Plan: Management- Inventory

Ascertain tree OWNERSHIP

• Do you have the authority

to remove/treat all the

trees that you’d like.

• Is ownership any of the

trees disputed?

Pennsylvania Department of Conservation and Natural Resources - Forestry Archive,

Bugwood.org

Preparing for the Emerald Ash Borer

http://nyis.info/eab


EAB Plan: Management- Removal and

• TREATMENT Options:

Chemical Treatment

– Insecticide versus removal

– Who will implement

• WHICH TREES?

– All publically owned ash

– All publically owned and some private ash that

have direct impact on public property

– Only high risk ash trees

David Cappaert, Michigan State University, Bugwood.org

EAB Plan: Management

Implementation

• Who will implement the management plan

– Staff/Employees

• Certifications and Training

– NYS DEC Certified Pesticide Applicator

– Arboriculture skills and experience

– Contractors

• Certifications and Trainings

– ISA Certified Arborist

– NYS DEC Certified Pesticide Applicator

Preparing for the Emerald Ash Borer

EAB Plan: Management- Wood

Where will the

WOOD go?

Disposal and Utilization

How will the wood

be USED?

Pennsylvania Department of Conservation and Natural Resources - Forestry Archive, Bugwood.org

Preparing for the Emerald Ash Borer

http://nyis.info/eab


EAB Plan: Management- Reforestation

What will you replant with?

• Schedule for replanting

• Recommended species:

– “Recommended Urban

Trees” CU- Urban

Horticulture Institute

Red Horsechestnut –

Cornell Woody Plant Database

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Educational Plan

Educating yourself, the plan writers and the

general public is important. How will you do

this?

• Work with CCE or other educational agencies

• Conduct your own public education

– Print and web resources

– Workshops and trainings

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Budget

How will your community pay for all of this?

• Develop multiple scenario budgets

• Consider all costs

• Look at your spectrum of management and

outreach options.

• Funding opportunities

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Why make a plan? Not just cost

• Political/Social

– Aesthetics of trees

– Infested trees don’t look dead right away

– “It’s not here yet, why bother now?”

• Liability and Safety

– Dead ash trees rot quickly, must act fast

– Who is responsible for which tree?

– Pesticide use

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Which scenario do you choose?

1. Remove all ash and replace all at once – costly

2. Remove ash and replace as funds are available.

3. Remove some trees and treat the remainder so

they remain alive and not a public health threat

until they can be removed.

4. Remove some trees, chose some trees to be

treated indefinitely until the EAB leaves, treat

others so they survive until they can be

removed.

5. Treat all trees indefinitely

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Factors to consider

• Cost of each scenario

• Impact of each scenario on your community

• Goals of your community forest and the ability

of your staff/volunteers/contractors to

implement plan

• Local opportunities you can take advantage of

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Cost to Remove

• Based on a small poll of some CNY

communities, the average cost to remove a

street tree is $440.

– Assumption- the average ash slated for removal

will have a smaller DBH than the average for all

trees being removed in a year, if all ash trees are

being removed. (Conservative)

– Range of $150 to $1325 per tree

• Size of tree, condition of tree, location of tree, and

contractor versus staff all affect price.

Cost to Treat

There are a variety of

treatment options

• Commercial Applicator

– ~$10 per inch of DBH per

year

– (including annualized multiyear

treatments)

• Soil drench

• Injections (preferred)

• Homeowner applied soil

drench (may not be preferable)

Chemical Treatment Considerations

Pros

• Retain canopy cover in heavy ash populated areas

• Can save trees until funds are available to remove them

• Can save trees long-term

• Mature trees are valuable

Cons

• Homeowner treatments- Do local ordinances allow them to treat

their own trees? Do you want them to?

• Effectiveness of treatment?

• Toxicity of chemicals- nerve toxins

• Timing is crucial (education and awareness)

• Injections could damage to the living tissue of a tree (frequency,

tree health, technician skill are all factors) 1

Community Cost Examples

Winnetka, Illinois: population 12,500

• Three pronged strategy to retain healthy ash

trees, remove infested and high risk ash trees,

and chemically treat healthy ash trees under 12”

diameter that are far from an infested tree.

• Worst case scenario (complete infestation): the

cost to remove all their ash trees:

$1.2 million

Community Forest Goals and Capacity

• What do you want your community forest to

look like?

– Tree lined streets, park trees, 100% planted, 50%

planted

• Do you have the skills in house or do you need

to contract?

– Does your staff need training?

– Can you afford contractors?

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Local Opportunities

• Shared community resources and

partnerships:

– Marshalling yards

– Shared equipment/talent

• Short-term economic development

Ash wood products

– Chips

Preparing for the Emerald Ash Borer

http://nyis.info/eab


Private Trees

• Individual homeowners will also be hit. Can

members of your community afford to remove or

treat their ash trees?

• Are there any opportunities for assistance funds?

• What ordinances are in place that govern private

trees? Do they need to be altered?

• Can you help ensure that your citizens won’t be

taken advantage of?

– These are all things that can be in your plan
