Treatment of Select Public Trees to protect against Emerald Ash Borer 

The City of Burnsville's Emerald Ash Borer (EAB) Management Plan dedicates funding over 10 years to treat nearly 2,500 “legacy” public ash trees in parks and boulevards, remove others that are in poor condition or become infested, and plant new trees.

In 2017, the City treated about 1,200 public ash trees to protect them from EAB and removed about 270 poor quality ash trees. In 2018, about 1,050 good quality trees are scheduled for treatment and 140 poor quality trees are being removed.

Many of the public ash trees being treated grow in street boulevards or right-of-ways. The standard right-of-way for residential properties extends 15 feet into yards from the curb. Ash trees growing within boulevards are considered public trees and, if they are of good quality, will be treated to protect them from EAB.

Residents with boulevard ash trees scheduled for treatment will be notified by postcard before treatment occurs. Ash trees on private property but not within the boulevard right-of-way are the responsibility of the property owner.


Treatment of Private Ash Trees Treatment rate for private ash.jpg

Residents may take advantage of City contract pricing to treat ash trees on their private property. In 2018, the City's contractor is Rainbow Treecare. The cost of treatments by Rainbow Treecare for private ash trees in Burnsville is $5.75 per inch of diameter at base height (DBH).To schedule a treatment, call Rainbow Treecare at (952) 767-6920.

DBH measuring.gifDB
 is a standard measure taken of the tree trunk at 4 1/2 feet above the ground. Tree companies will measure this for you. However, if you want to measure the DBH yourself, wrap a measuring tape around the tree trunk at 4 1/2 feet above the ground. Divide that number by 3.14 to calculate DBH.

  



NOTE: Residents are responsible for 
the full cost of treatments for private ash trees. Any City-licensed tree contractor with a commercial pesticide applicator license may be hired to perform an EAB treatment.



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. EAB infestations have been confirmed in several Twin City metro locations.

In December 2014, the Minnesota Department of Agriculture (MDA) confirmed the first infestation in Dakota County at Lebanon Hills Regional Park. In January 2016, EAB was confirmed in Apple Valley. In December 2017, an infestation was found in Lakeville's Oak Shores Park, less than 1/4 mile from the Burnsville city limit.

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



Dakota County under EAB Quarantine


Dakota County is on the MDA's list of EAB 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).

What's the City's 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 full plan: City of Burnsville Emerald Ash Borer Management Plan.  For a synopsis of the plan, read the Summary of the EAB 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."
