3/30/16 - Urban Forest Commission approves the EAB Management Plan


Emerald Ash Borer (EAB), an invasive insect from Asia first detected in the U.S. in 2002 and in Minnesota in 2009, has now been found in Duluth on Park Point.  It is considered the most destructive forest pest ever seen in North America.  EAB selectively targets Ash trees and its larvae eat tunnels under the bark that cut off the nutrient and water supply to the tree, which results in the tree's death.  No effective large-scale control method has been discovered.

An emergency quarantine was declared by the Minnesota Department of Agriculture of Park Point and went into effect on November 15, 2015 in order to help prevent EAB from spreading. A formal quarantine is now in place.

The quarantine limits the movement of Ash tree parts and hardwood firewood on Park Point because the biggest risk of spreading EAB comes from transporting materials that harbor the insect larvae. 

By itself, EAB only usually travels about ½ mile from the tree where it emerges, but the transport of infested material has allowed it to spread much faster.


Limiting this spread in Minnesota is particularly important. Of all the states, Minnesota is host to the largest number of Ash trees, about one billion. 

On Duluth boulevards, Ash trees are second only to Maple in population numbers.  Because EAB kills the Ash trees it infests, its local spread would result in a hazardous and difficult to manage number of dead standing trees on city streets, not to mention environmental degradation of our parks and surrounding forests. State and nation-wide, its spread poses substantial economic and environmental consequences.

There are a number of things people can do to help prevent the spread of Emerald Ash Borer. The MDA has identified three easy steps to take:

Don’t transport firewood. Buy firewood locally from approved vendors, and burn it where you buy it.
Be aware of the quarantine restrictions.  If you live in a quarantined county, be aware of the restrictions on movement of products such as ash trees, wood chips, and firewood.
Watch your ash trees for infestation. If you think your ash tree is infested, go to and use the “Do I Have Emerald Ash Borer?” guide.
