Strategies for Battling the Emerald Ash Borer

Protecting our rural character and natural resources

                   through community-based land conservation.

The Emerald Ash Borer Presentation

Thursday, February 22


The emerald ash borer is a small green tree pest that has already killed millions of ash trees across the US and is now here in Bucks County. It affects all ash tree species and is expected to kill 99% of all ash trees and up to 50% of our total tree canopy.


On Thursday, February 22, we learned what we can do to minimize the impact from Donald Eggen of the Bureau of  Forestry and Kendra McMillin from Beyond Management LLC at a standing-room only event at the Tinicum Elementary School.



We first wrote about the massive threat posed by the Emerald Ash Borer (EAB) to Pennsylvania’s forests, landscapes, and ecosystems in the Spring 2013 Common Ground. Unfortunately, infestations of the Asian green beetle continue to be a serious concern. Foresters and biologists are still working to find a chemical or biological control, but for now, Pennsylvania’s 300 million ash trees are vulnerable and if infected, will die quickly.


A balanced or “selective” management approach may include removal of some trees, treatment with insecticides, and replanting with other natives. Ideally, treatment of some native ash trees, especially rarer species, will provide a seed source for future collection and preservation of their local genome. Ottsville’s Martie and Neil Kyde decided that losing even one of their ash trees was not an option. They hired an arborist who spent a day on their 30-acre, forested property identifying and tagging 39 ash trees with diameters of 4” or more. Next, licensed applicators spent a day injecting the trees with a chemical pesticide (Emamectin benzoate), mixed and measured specifically for each tree, to protect them from the EAB for at least two years.


If you're concerned about the health and survival of the ash trees on your property, we recommend you speak with more than one professional (such as a forester, arborist, or resource protection expert) to find the best fit for your personal vision, resource management goals and financial needs. Remember, the strategy that works for your neighbor may not be the best fit for you, so it's always good to gather as much information as possible.

Kendra is a resource management professional that can develop management plans for battling the Emerald Ash Borer. She can also direct both qualifying municipalities and private landowners to available grants to help allay the cost of treatment.





The DCNR Bureau of Forestry has assigned a service forester to each county. These individuals offer information and advice to managers of rural and community forests and are a resource for the citizens of Pennsylvania, helping to guide landowners and residents in the practice of sustainable forestry. The designated forester for Bucks County is Heather Kerr. You can reach her at (610) 489-8326 or at
