Emerald Ash Borer
City Begins Treatment of Public Ash Trees

In June 2014, in partnership with project consultant Rainbow Treecare, the City treated 478 public, good quality ash trees. This year, the City and Rainbow Treecare treated an additional 928 ash trees, and the City removed 120 ash trees that were in poor condition. 

Resident Ash Tree Treatment
Residents will also have the opportunity to take advantage of the City’s contract prices to treat ash trees on their private property. Residents will be responsible for the full cost of these private treatments. Contact Rainbow Treecare at 952-767-6920 for pricing and scheduling. The contract prices are valid through the end of 2015. Residents are also encouraged to volunteer to pay for treatment of other existing ash trees in their neighborhoods.

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

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. To see where EAB has been found in Minnesota, check out the Minnesota Department of Agriculture's EAB Status Map.

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 larvae_David Cappaert_Michigan State Univ_1460071-SMPT.jpgeastern Asia but were discovered in Michigan and Ontario in 2002. The larvae (shown on the right) 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 Are Those Purple Boxes?
Residents may notice the Minnesota Department of Agriculture's EAB traps hanging from ash trees in local parks. The three-sided purple traps use Manuka oil--which has a scent similar to that given off by a distressed ash tree--to attract the beetles. The traps are coated with a sticky substance to ensnare the beetles. Why purple? The U.S. Department of Agriculture determined through scientific testing that the beetles are attracted to the color purple.

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."
