Emerald ash borer (EAB) is an invasive forest insect from Asia responsible for the deaths of millions of ash trees throughout the eastern half of the United States.
EAB infests and kills weak and healthy ash trees alike, and all species of ash native to North America are vulnerable to EAB attack. EAB is spreading across the nation and was first found in Minnesota in St. Paul in 2009 and in Minneapolis in 2010. It was discovered in downtown Apple Valley in 2015 and it continues to spread. Based on annual winter surveys, city staff have confirmed additional EAB infestations throughout Apple Valley. Infestations are also now confirmed in several neighborhoods and all of our surrounding cities.
Ash trees with confirmed EAB infestations must be removed and disposed of prior to the beetles emerging in May. As part of the City’s inspection process, City staff introduce themselves to area businesses or residents prior to surveying the area for the borer. Based on the outcome of the survey, property owners are then notified of removal requirements. In 2010 the City adopted an EAB Management Plan which helps to guide our efforts to proactively manage the spread of EAB within the City. The City recommends preventatively treating prized trees, taking down less desirable trees, and planting new trees with diversity in mind.
