Key Questions

• How well does the report capture the complexity and offer a

practical strategy for addressing the threat of emerald ash borer?

• Considering the information in the report, how can we move

the issue forward?

• What does success look like and how should we measure,

and/or monitor it?

EAB populations grow slowly at first but then faster and faster Many trees may die in a short amount

• f time when EAB

populations are high

What are the Concerns? Community Forests and Ash Forests

Community Forests

• Nearly 3 million community ash trees
• 1-in-5 community forest trees are ash
• Up to 60% ash in some communities
• EAB kill rate over 99%
• Kills saplings down to 1” in diameter

• Communities need resources to:
• Inventory their community forests
• Make management plans
• Treat and remove ash
• Plant diverse replacement trees
• Educate residents
• Help homeowners

Community Forests and Citizens

The Issue/ The Need

Ash Forests

• Over 1 billion ash trees statewide
• 1 million acres of ash forest statewide
• 2nd most common tree
• Minnesota has more ash than any
• ther state

• Ecological Concerns
• Hydrology – e.g. “swamping”
• Habitat loss
• Reforestation
• Economic Concerns
• Markets
• Limited harvest time - winter

Key Recommendation – Support Communities

Gary Michael | Cooperative Forest Management Supervisor, DNR Page 20-21

Support Communities

• Increase technical and financial

assistance to communities

• Inventory
• Management Plans and

Implementation assistance

• Promote Diversity
• Provide training

Environmental Wood Supply: Processing Tree Waste Into Biofuel

Minnesota Counties Impacted by Emerald Ash Borer

Increasing Impact of EAB – YTD 2019

• Estimated 30% of our brush and log

intake identified as being EAB related.

• 52% of tree waste from the City of

Saint Paul is EAB related (2017-18

• avg. 23%)
• EWS is averaging a 51% increase in

delivered tree waste compared to the past 5 years.

Resolution

• Approve the 2019 Emerald Ash

Borer in Minnesota report

• Support cross-agency work to

implement recommendations

• Convene future meetings to

monitor progress and invite public input

Key Questions

• How well does the report capture the complexity and offer a

practical strategy for addressing the threat of emerald ash borer?

• Considering the information in the report, how can we move

the issue forward?

• What does success look like and how should we measure,

and/or monitor it?
