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.

Marianne Prue, Ohio Department of Natural Resources - Division of Forestry, Bugwood.org


Beetle larva eat the living tissue (cambium) between the bark and the wood, effectively girdling the tree.

Effects of EABAs the Emerald Ash Borer established, ash trees

will begin to die.

Signs of EAB

• “D” shaped exit hole• “S” galleries under the

bark

Symptoms of EAB

• Suckering from the base and stem

• Dieback in the canopy

• Excessive woodpecker activity

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.


Where is the Emerald Ash Borer?


No untreated ash materials can be moved from these areas


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

Can you afford to manage them?

Can you afford not to?

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?

Community Preparedness Plan

Work with your local leaders and community to develop a plan that will help minimize the ECONOMIC AND ENVIRONMENTAL IMPACT of the emerald ash borer.

• Use the NYS EAB Community Preparedness Plan Development Workbook at the NY Invasive Species EAB web site: http://www.nyis.org/eab

Daniel Herms, The Ohio State University, Bugwood.org


Why make a plan?

• To identify the: PEOPLE RESOURCES MONEY

available to help manage the effects of 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


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


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


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?



EAB Plan: Management- Removal and Chemical Treatment

• TREATMENT Options:– 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



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


EAB Plan: Management- Wood Disposal and Utilization

Where will the WOOD go?

How will the wood be USED?



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


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


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


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


Which scenario do you choose?

1. Remove all ash and replace all at once – costly2. 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


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


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.


Your Community?Sherburne, NY25 ash trees, 7% of 354

total, avg. DBH 9.75”Est. Cost to remove:

$15,000Est. Cost to Treat

$1,250/yr for 12 + years?

SWAT Data- Courtesy of Fred Cowett


Ithaca, Cayuga Heights and Cornell Campus

762 ash trees (3.1%)

$335,820 removal estimate



Cost to TreatThere are a variety of

treatment options• Commercial Applicator – ~$10 per inch of DBH per

year – (including annualized multi-

year 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


Your Community?Sherburne, NY25 ash trees, 7% of 354

total, avg. DBH 9.75”Est. Cost to remove: $11,000Est. Cost to Treat ($10/DBH)

$2,437.50/appication for 121 (apply every 3 years)



Community Cost Examples

Deforest, Wisconsin: population 8,500• 455 ash trees in urban forest (13% of total)– 330 are under 6” in diameter, decreasing the

removal cost (average $700-$800 per tree)• Village estimated removal cost:

$75,000- $100,000

Village of DeForest web site: http://www.vi.deforest.wi.us/



Wilmette, Illinois: population 26,700• Propose spending $2 million over a five year

period to remove and replace public ash trees• Approximately 2855 ash trees slated• Fund created though a 2% tax increase over a

five year period.

Taken from a presentation by Tom Dilley, Natural Resources Specialist with the USDA Forest Service, NA, S&PF



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

Taken from a presentation by Tom Dilley, Natural Resources Specialist with the USDA Forest Service, NA, S&PF


Community Impact

Think of this as your community.

How will the death of all these trees effect your citizens?

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?


Local Opportunities

• Shared community resources and partnerships:– Marshalling yards– Shared equipment/talent

• Short-term economic development– Ash wood products– Chips


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


What will this neighborhood look like?

West Henrietta, NY


Why make a plan?

• It takes time to train personnel• It takes time to complete an inventory• It takes time to make thoughtful decisions• It takes time to develop intercommunity

connections• It takes time to create wood utilization

projects• It takes time to identify funding sources
