Tree Removal

Madison has confirmed EAB in trees removed from Home Depot and Pizzeria Uno on the east side. This location is within 3 miles of Sun Prairie's city limits. When the Ash borer infects an Ash tree, the tree dies relatively quickly (4 to 6 years) resulting in the need to remove the tree before the weakened condition results in damage from falling.

Parks Department Survey

The Parks Department conducted a survey of city Ash tree size and condition last year so that the correct actions can be taken. With the probability of EAB in Sun Prairie, action is being taken to slow its spread through the city. You can help by following these recommendations:

  • Do not transport cut Ash tree wood into or out of Sun Prairie (per state statue, no more than 10 miles).
  • Become aware of Ash trees in your neighborhood and specifically on your property.
  • Consider a plan to treat your private Ash tree(s) against the EAB; however, treating prior to infestation has not been proven beneficial. Treatments are not permitted on street ash trees located in the city right-of-way.
  • Consider a plan to remove before or once the Emerald Ash Borer is detected in Sun Prairie.
  • Research the Emerald Ash Borer infestation. Two good web sites are:

Tree Replacement Plan

The Forestry Department is hopeful that they will be able to replace all Ash trees that are removed with approved city trees. This will depend on budgetary constraints. If a tree has been removed from your property and you do not want it replaced, you will need to submit that request in writing to City of Sun Prairie (Attention Forestry Department) at 300 E. Main Street. You can also send an email to the Public Works department as well.

Further updates will be available after more information has been collected by the city. If you have any questions, please call 608-837-3050.
