Emerald Ash Borer Management Plan – City of Arden Hills Page 2 <br />Adopted by the City Council on July 30, 2012 <br /> <br />not known, though it is worth noting that the trees are only a half mile from interstate highway <br />35W and in other states the principal spread of EAB has been along travel corridors. <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 difficult to <br />determine when EAB will reach Arden Hills. It is estimated that as much as 12.3% of Arden <br />Hills’ urban forest is compiled of ash trees based on a Minnesota Department of Natural <br />Resources survey (Minnesota Department of Natural Resources 2010 Community Tree Survey. Survey <br />of front yard and 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. <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 />The City of Arden Hills has done the following to prepare for the EAB problem: <br />• Completed an electronic inventory with the software, “Simple Trees” of all trees in the <br />ROW along City streets, parks and trails. This will help the City monitor the condition <br />of ash trees throughout the City. <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 />• 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.
