,ARZEN HILLS <br /> Emerald Ash Borer Management Plan <br /> Background <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 predatt rs, or controls in North America the <br /> Q <br /> insect has spread to 13 states and two Canadian proven k <br /> EAB adults can fly at least a half mile from tl"ee when t e'y- emerge. However, new <br /> infestations are most often created when peransport infested � rsery ash trees, logs or <br /> firewood into uninfested areas. TransportWo of firewood has been;r gulated to reduce the <br /> spread of EAB. Ramsey County is a quarantip�.rea, which prohibits th tansportation of ash <br /> wood outside the County.

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 <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 /> Emerald Ash Borer Management Plan-City of Arden Hills Page 1 <br />
