Emerald Ash Borer Management Plan – City of Arden Hills Page 2 <br />Adopted by the City Council on April 11, 2022 <br /> <br />Analysis of the infestation showed that the EAB had been present for 3-4 years, which is <br />consistent with the insect’s path of destruction. Symptoms are slow to appear and once EAB is <br />actually found, it is estimated that it has already been present for 3-5 years. It is believed that the <br />emerald ash borer was first detected in Arden Hills in 2014 and, since then, its population has <br />continued to multiply and spread. It is estimated that as much as 12.3% of Arden Hills’ urban <br />forest is compiled of ash trees based on a Minnesota Department of Natural Resources survey <br />(Minnesota Department of Natural Resources 2010 Community Tree Survey. Survey of front yard and <br />street trees in residential and commercial sampling areas) <br /> <br />To date, North American communities have not been successful in eradicating EAB once found. <br />EAB typically builds in population and eventually infests and kills all variety of ash trees. <br /> <br />Resident Education <br /> <br />Resident education and communication are key components of managing the impact of the EAB, <br />especially as more information becomes available. Public information is available to residents <br />through the City’s website, newsletters, and available at City Hall. Residents can also find <br />information about EAB management on the website for the Minnesota Department of <br />Agriculture: https://www.mda.state.mn.us/emerald-ash-borer-management-guidelines <br /> <br />Homeowners may treat their private trees, provided they use a licensed treatment contractor who <br />adheres to the City’s standards to protect surface and ground water. <br /> <br />Mitigation <br /> <br />Although it is not possible to stop the spread of invasive species, like the Emerald Ash Borer, the <br />City of Arden Hills’ EAB Management Plan is designed to help manage the impacts. The City’s <br />mitigation of EAB will be similar to the policy and intent of Dutch Elm and Oak Wilt Disease, <br />which attempts to control and prevent the spread of these diseases. <br /> <br />The City of Arden Hills has done the following to prepare for the EAB problem: <br /> <br />• Completed an electronic inventory with GIS software of all trees in the ROW along City <br />streets, parks and trails. This will help the City monitor the condition of ash trees <br />throughout the City. <br /> <br />• Clarified owner responsibilities for all Right of Way trees abutting a City road. These <br />changes were done with the amendment of Chapter 3 of the City Code in October of <br />2011. <br /> <br />• Updated the City’s Tree and Vegetation Ordinance, Chapter 7 to add ash trees to the <br />diseased trees that must be removed to prevent the spread of the disease. This ordinance <br />permits the City to enter private property for inspection, order the removal of diseased <br />trees and abate the nuisance upon non-compliance of property owners.
