Emerald Ash Borer Management

Vadnais Heights Emerald Ash Borer Management


An Emerald Ash Borer (EAB) infestation was confirmed in Vadnais Heights in the summer of 2019 by the MN Department of Agriculture. Since then, staff has identified infested trees along Highway 96 progressing southward. EAB affected trees have also been identified at Greenhaven, Community, Bear and Bridgewood parks. 

Beginning in May 2021, Langer's Tree Service has been hired to remove trees affected in the parks. Trees identified with orange tape (see image) are marked for removal. Ramsey County has agreed to remove all the Ash trees along Highway 96, likely to take place in late summer or fall of 2021.

The City Council adopted a management plan on August 4, 2021.

What is Emerald Ash Borer?


The Emerald Ash Borer (EAB) is an invasive beetle from Asia that was discovered in the United States during the summer of 2002 near Detroit, Michigan. EAB larvae feed on the inner bark of ash trees and disrupt the tree‘s ability to transport water and nutrients, killing the tree. Once an ash tree is infested, it has almost zero chance of survival unless it is treated in time. EAB populations can grow exponentially each year because the beetle has few natural predators and our ash trees have limited natural defenses.  When EAB is not managed, annual ash tree deaths can quickly overwhelm the ability to remove dead and dying trees.

What Can Homeowners Do? 


City staff resources are limited, but we will respond and mark trees as a nuisance if necessary. Residents interested in possibly saving their tree should contact an arborist as soon as possible. If you have a dead or dying tree, please make arrangements to have it removed. Please visit the below resources for more information on how to slow the spread of EAB in our community.
