Emerald Ash Borer

Has the Emerald Ash Borer Arrived in Burnsville?Emerald ash borer and a penny

The Emerald Ash Borer (EAB) has not been found in Burnsville yet, but it is likely only a matter of time until this unwelcome guest shows up at our doorstep. However, EAB infestations have been confirmed in several Twin City metro locations, including St. Paul, Minneapolis, Falcon Heights, Shoreview, and Bloomington.

In December 2014, the Minnesota Department of Agriculture (MDA) confirmed the first infestation in Dakota County at Lebanon Hills Regional Park. You can read the news release about the discovery here.

Dakota County under EAB Quarantine

Because of the EAB discovery, Dakota County has been added to the MDA's list of quarantined counties. The quarantine restricts the movement of ash trees, ash limbs and branches, ash stumps and roots, ash logs, ash lumber, ash wood, or ash bark chips from a quarantined county into a non-quarantined county. 

In addition, hardwood firewood of any kind (ash, oak, etc.) may not be moved from a quarantined county into a non-quarantine county.  More details about the quarantine can be found on the Emerald Ash Borer - Minnesota Quarantine webpage.

What is the Emerald Ash Borer and Why is it a Problem?

EAB are invasive, non-native beetles that attack and kill ash trees.  EAB are native to eastern Asia but were discovered in Michigan and Ontario in 2002. The larvae of these shiny green beetles tunnel beneath the bark of ash trees and gnaws away at the living tissue of ash trees until the tree eventually dies, usually 2 to 4 years after being infected.

Not every green bug is an Emerald Ash Borer. Here is a guide to Insects in Minnesota that may be Confused with Emerald Ash Borer. Below is a side-by-side comparison of an Emerald Ash Borer and the Six-Spotted Tiger Beetle (native insect).

Does the City of Burnsville have a plan to deal with EAB?

The City of Burnsville approved a plan in April 2013 to protect a portion of the City's trees from the invasive Emerald Ash Borer.  Read the plan: City of Burnsville Emerald Ash Borer Management Plan.

In addition, the City is working with the Minnesota Department of Agriculture by monitoring EAB traps in our park system, along with inspecting any suspicious ash trees that die in our community.

What's Your Plan?

The City's 10-year EAB management plan covers public ash trees. However, it does not cover the thousands of ash trees on private property. If interested, all residents will have the opportunity to take advantage of the City's contract prices to treat ash trees on their private property. Additional details will be forthcoming.

If you have one or more ash trees, you should consider whether you want to save or remove them. This Decision Guide can help you determine the best course of action for your ash tree(s).  You may also want to explore the Signs and Symptoms of an Emerald Ash Borer infestation. You can also consult a professional arborist to examine your trees. The University of Minnesota offers advice on "How to Hire a Professional Arborist."
