Emerald Ash Borer

What is Emerald Ash Borer?

Emerald Ash Borer (EAB) is a metallic-green beetle native to Asia. The EAB larva tunnels through the tree cutting off the ability to transport nutrients which ultimately kills the ash tree. Over time, EAB will destroy all ash trees. The City of Oskaloosa is working to remove all ash trees in the right-of-way to prevent future problems associated with dying trees.

What is the City's Ash Tree Plan?

The City of Oskaloosa plans to remove all ash trees in the city right-of-way including city parks and city property. As of the summer of 2014, the city has identified 175 ash trees in the right-of-way. The plan to remove these trees is based off of a system that evaluates each tree. In order to take down the least attractive trees first, the city evaluates all ash trees based off of location to power lines, proximity to sidewalks, proximity to the curb and gutter, and the overall health of the tree. The goal of this program is to continue to gain benefits from healthy ash trees while systematically removing them to avoid hazards caused by EAB. The city is working to help replace each ash tree by working with residents who lose one in the right-of-way. The city wants to ensure that Oskaloosa continues to have an excellent tree stock with a strong urban canopy.

When will I know if my ash tree in the right-of-way will be removed?

The city will contact you in a letter sent to your residence. The letter will give some contact information and also a time frame of when the tree will come down.

How can I get the tree replaced?

The city will work with each property owner to ensure that they receive a replacement tree. The best way to receive a new tree is to sign up for a new one during the yearly event "Plant Some Shade". Plant Some Shade is a program put on by MidAmerican Energy and hosted by Oskaloosa Trees Forever. This program allows a MidAmerican Energy customer to purchase a tree, usually 8 to 10 feet in height, for a significantly discounted price.

What if I want another tree planted but not in my yard?

The city can work with each resident on ensuring that another tree is planted in another location to prevent rapid tree loss in Oskaloosa. Trees will most likely be planted at one of the public parks.
