<br /> <br /> <br /> <br /> <br /> <br />Emerald Ash Borer Management Plan <br />City of St. Anthony Village, MN <br />WSB Project No. 022315-000 Page 2 <br />2.0 Introduction <br />EAB (Agrilus planipennis Fairmaire ) is a non-native invasive wood boring beetle with <br />larvae that tunnel under the bark in the living tissue, disrupting the tree’s ability to <br />transport water and nutrients. It was first detected in Detroit, Michigan in 2002, most <br />likely introduced to North America on wood packing materials originating from Asia. <br />Scientists believe it could have been introduced as early as 1990, so the insect had <br />over ten years to build its population without any proactive management in that area. <br />Since that time, EAB has spread to at least 35 states and 6 Canadian provinces. <br />Emerald ash borer has killed hundreds of millions of ash trees where it becomes <br />established. <br />The USDA Forest Service EAB website states “…emerald ash borer is the most <br />destructive invasive forest insect ever to have invaded North America.” Ash trees <br />were frequently the default replacement for elm trees lost to Dutch elm disease in <br />the late 1970’s and 80s. They traditionally survive in soil conditions that many other <br />trees cannot and are selected for difficult growing sites. <br />Map 1: USDA Approximate Range of Ash Species in the Continuous <br />United States with EAB Positives, March 2023 <br /> <br />According to the state’s Department of Natural Resources, Minnesota has 2.65 <br />million ash trees in communities, and about 1.1 billion ash trees in total growing in <br />forests and communities, the most of any state in the country.
