Emerald Ash Borer Management Plan – City of Arden Hills Page 1 <br />Adopted by the City Council on July 30, 2012 <br /> <br /> <br />Emerald Ash Borer Management Plan <br /> <br />Background <br /> <br />Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered <br />in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash <br />foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash <br />trees, disrupting the tree's ability to transport water and nutrients. Emerald ash borer probably <br />arrived in the United States on solid wood packing material carried in cargo ships or airplanes <br />originating in its native Asia. Without any natural predators or controls in North America the <br />insect has spread to 13 states and two Canadian provinces. <br /> <br />EAB adults can fly at least a half mile from the tree when they emerge. However, new <br />infestations are most often created when people transport infested nursery ash trees, logs or <br />firewood into uninfested areas. Transportation of firewood has been regulated to reduce the <br />spread of EAB. Ramsey County is a quarantine area, which prohibits the transportation of ash <br />wood outside the County. The Minnesota Department of Agriculture is responsible for <br />quarantine enforcement and penalties. <br /> <br />Signs and Symptoms <br /> <br />Signs and symptoms of EAB include: <br />• Bark splitting <br />o Vertical fissures on bark <br />o Galleries exposed under bark split <br />• Serpentine galleries and “D” shaped exit holes <br />• The presence of EAB or larvae. <br />o Adult – Bright, metallic green/ ½ inch long, flattened back <br />o Larva – Creamy white, legless <br />• Canopy dieback <br />o Begins in top one-third of canopy <br />o Progresses until tree is bare <br />• Increased woodpecker activity. <br />• Sprouting of epicormic shoots from the base of the tree <br /> <br />Current EAB situation <br />St. Paul and Falcon Heights confirmed EAB discovery in May of 2009. The City of Shoreview <br />confirmed EAB discovery in the vicinity of County Road I and Schutta Road in July of 2011. <br />The Department of Agriculture has since identified 11 trees in this neighborhood with confirmed <br />EAB and several that are suspected and being monitored. How these trees became infested is
