On December 23rd the Minnesota Department of Agriculture confirmed Emerald Ash Borer in your county.   The EAB infestation was found in an ash tree in Lebanon Hills Regional Park in the city of Eagan, just north of the border with Apple Valley.  The infested tree was detected through a routine visual survey of ash trees being conducted by the MDA. Dakota County was on the border of quarantined areas.  Unfortunately, now IT’S quarantined just as Hennepin, Houston, Olmsted, Ramsey, and Winona counties are in a state and federal quarantine.

MDA Entomologist Mark Abrahamson says the spread of EAB in Minnesota has been slower but it’s still presenting itself.  Emerald ash borer larvae kill ash trees by tunneling into the wood and feeding on the tree’s nutrients. Since its accidental introduction into North America, EAB has killed tens of millions of ash trees in 24 states. The invasive insect was first discovered in Minnesota in 2009. The last county to be quarantined for EAB was Olmsted in August 2014.

The biggest risk of spreading EAB comes from people unknowingly moving firewood or other ash products harboring larvae. There are three easy steps Minnesotans can take to keep EAB from spreading:

  • Don’t transport firewood.
  • Be aware of the quarantine restrictions.
  • Watch your ash trees for infestation.
