The Emerald Ash Borer (EAB) is a notorious invasive beetle known for its destructive impact on ash trees across North America. Since its initial detection in Michigan in 2002, the EAB has spread relentlessly, first appearing in Wisconsin’s Fox Valley in 2008. The situation here remains critical, as EAB continues to threaten both urban and rural ash tree populations, significantly altering the state’s ecosystem and urban canopies. Fox Valley Tree Care has had the opportunity to save trees with treatment and help homeowners find alternatives when restoration was not possible. Here’s a rundown of what we have learned.
The Current State of Emerald Ash Borer in Wisconsin
Wisconsin’s ash trees hold significant ecological and environmental value, supporting biodiversity and offering shade to urban and residential areas. However, the presence of the EAB has put these trees at great risk. EAB larvae feed on the inner bark of ash trees, disrupting their nutrient and water transport systems, ultimately leading to the tree’s death. Researchers, arborists, and local authorities in Wisconsin are actively exploring and implementing strategies to slow its impact, but in many places, emerald ash borer tree damage has already changed the landscape.
Emerald Ash Borer Treatment and prevention
If your ash is infested, we have a number of treatment options to perhaps save your tree and protect the others around it.
- Insecticide Treatment: This is the most common emerald ash borer treatment. These injections circulate through the tree’s vascular system, targeting feeding larvae. When properly administered by a licensed tree care professional, some trunk injections have shown to be 90% to 95% effective at controlling EAB in healthy trees, making this treatment the most effective method by far.
- Cultural Practices: Recommendations may include removing and destroying infested trees to control EAB spread. Implementing good cultural practices such as mulching and pruning can also enhance tree health and resilience against pest invasions. Cultural practices can reduce the overall stress on a tree which in turn will make it healthier in all species. However, a stressed tree is more likely to see damage faster but will not stop anything without insecticide treatment.
Replanting Non-Ash Species, A Future-Proof Plan
Sadly, sometimes the ash tree cannot be saved. In those scenarios, replanting becomes essential for sustaining urban canopies and ecological balance. We recommend diversifying the types of trees on your property to reduce the impact of infestation by pests like the EAB. Varieties such as oak, maple, or birch may be the best replacement, depending on local conditions and presence of other pests. Fox Valley Tree Care can guide you to species that are well-adapted to Wisconsin’s climate and the soil conditions in your yard to promote longevity and health.
