Emerald ash borer (EAB), Agrilus planipennis, is an invasive beetle from Asia that has devastated ash tree populations across North America. As of 2022, approximately 8 billion ash trees in North America are at risk due to EAB infestations. caryinstitute.org

Ash trees have shown mortality rates in heavily infested areas, over 99% of ash trees may die within 8-10 years of EAB establishment. invasivespeciescentre.ca  EAB has been detected in 36 U.S. states and the District of Columbia, with infestations continuing to spread.aphis.usda.gov  The loss of ash trees has led to significant economic costs, including the removal and replacement of trees in urban areas. For example, in Minneapolis, ash trees constitute slightly more than 20% of the urban forest.  The removal of ash trees has altered forest structures, affecting wildlife habitats and leading to increased numbers of invasive plant species. 

Efforts to manage and control EAB include monitoring, biological control, and chemical treatments. However, the widespread nature of the infestation suggests that complete eradication is unlikely. 

The ongoing spread of EAB underscores the importance of early detection and management strategies to mitigate its impact on ash tree populations. Roots as a company constantly educating our team to assist with chemical treatments and removal of trees at risk depending on health.  Early detection is key to combat this major issue.
