Our urban forests provide many benefits to our communities, from reduced heating and cooling costs to beautification, but they are vulnerable to the potential impacts of a new pest, Emerald ash borer (Agrilus planipennis). EAB is a non-native beetle that has destroyed urban ash trees (Fraximus sp.) across the Midwest, costing municipalities millions of dollars in damage.
The destructive pest is now found in many Wisconsin counties. These counties are now under quarantine, with additional counties quarantined due to their proximity to infestations. See a map of current EAB records by clicking here.

What We're Doing
EAB Workshop: Save Your Ash!
An emerald ash borer workshop for urban and woodlot residents.
Saturday, June 3rd, 9:00am - 4:00pm
Mosquito Hill Nature Center, New London, WI
Join us to find out how to spot it, what to do about it, and what to do with the valuable wood from your trees! Details and registration info at: Save your ash!
Green Ribbon Campaign:
The 2016 Green Ribbon Campaigns in Stevens Point and Wausau, Princeton, Rothschild, and Spencer highlighted what these municipalities are doing to prepare for EAB and what city residents can do to prepare as well.

Preparedness planning for small municipalities:
To prepare for EAB, the municipalities of Friendship, New Lisbon, Schofield, and Elderon are partnering with Golden Sands to receive an inventory of their ash trees and a complete EAB preparedness plan. We are conducting urban ash tree inventories and writing EAB management plans for each of our partner municipalities.
Without proper planning, cities can find themselves with hundreds of dead and dying street trees, posing safety risks and expensive removal and replanting costs. Proper planning can help.
Preparedness planning includes:
1. Educate the community about EAB
2. Inventory and locate urban and rural ash trees
3. Identify and prioritize the removal of hazardous trees
4. Budget to treat priority trees
5. Plan for disposal of removed trees
6. Replant with a diverse mix of tree species
