Emerald Ash Borer Project
Emerald Ash Borer
What is Emerald Ash Borer Disease?
Emerald Ash Borer is an invasive beetle that poses a significant threat to our ash trees. Originating from Asia, these metallic-green pests attack ash trees, disrupting their nutrient flow and ultimately leading to their demise. Without intervention, the consequences for our city's tree canopy could be severe. The City of Henderson has more than 100 public ash trees and nearly 100% of ash trees that become infected will die within five years.
Recognizing EAB Infestation
Be vigilant for signs of infestation, including:
Thinning Canopy: A gradual reduction in leaf density.
S-shaped Galleries: Serpentine patterns under the bark created by EAB larvae.
D-shaped Exit Holes: Small, distinctive exit holes left by emerging adult beetles.
City Initiatives
In collaboration with the Minnesota Department of Natural Resources, the City of Henderson is actively addressing the threat of EAB. The City of Henderson has secured grant funding to remove and replace ash trees on public property that pose safety hazards, ensuring the health and resilience of our urban forest. Find out more about the 2023 Preparing for EAB grants program here and the Shade Tree Bonding Grant here.
These grant funds are allocated for the removal of ash trees, stump grinding, tree replacement, replanting site preparation, and the installation of watering bags. The City of Henderson was awarded a total of $100,000: $15,000 from the 2023 Preparing for EAB grant program and $85,000 from the Shade Tree Bonding grant program.
Preventative Measures
Insecticide Treatments: Certified arborists can apply insecticides to protect healthy ash trees. Though early detection is key for successful treatment.
Tree Removal and Replacement: Proactively removing and replacing affected trees helps prevent the spread of EAB and maintains the integrity of our urban landscape.
The decision to treat or remove/replace private trees rests with the property owner but it’s important to know that if you find signs of EAB disease, you should notify the City.
The City encourages residents to replace trees lost to EAB disease with trees approved by the Minnesota Department of Natural Resources, or to remove and replace ash trees in advance of EAB infestation as a way of preserving the tree canopy. The City of Henderson will select trees from the following approved species:
Get Involved
Educate Yourself: Stay informed about EAB and its impact on ash trees.
Report Infestations: If you notice signs of EAB or suspect an infestation, report it to the City of Henderson.
Tree Planting Programs: Participate in community tree-removal/replacement initiatives to diversify our urban forest. Grant funds can only be used on public property, but this does include all ash trees along the public right-of-way or boulevard and parks and trails.
If you have questions about whether your tree is considered private or public, please contact the City offices.
