Proactive strategy aims to lessen environmental impact; property owners encouraged to make plans for their ash trees
Emerald ash borer (EAB), a tree-killing pest of ash trees, was confirmed in Coralville in early 2017. The small metallic green beetle, which is native to Asia, arrived in the eastern United States in 2002 before moving to the Midwest through firewood, sawmill logs, and nursery plants. As of April 2017, emerald ash borer has been confirmed in 45 counties in Iowa. Following patterns in the Midwest, Coralville can expect to lose the majority of the ash tree population.
Coralville has approximately 300 City-owned ash trees in parks and streetscapes. On April 11, 2017, the City Council approved a five-year emerald ash borer response plan to mitigate the spread of emerald ash borer in public ash trees through ash tree treatments, removals, and replanting efforts to diversify Coralville’s urban forest.
Beginning in spring 2017, approximately 200 eligible City-owned ash trees in City parks and streetscapes will be treated with trunk injections. Areas undergoing treatment will be signed. The City’s contractor, TruGreen, will not be entering yards nor treating any trees on private property.
Property owners are responsible for removing or treating ash trees on their own property, including their yard. Planting a tree in the right of way requires a tree planting permit. If an ash tree was planted in the right of way with a permit, the City will remove the ash tree if it is dead, dying, or diseased. If an ash tree was planted in the right of way without a permit, the property owner will be notified that the ash tree must be removed at their own cost when it is dead, dying, or diseased.
A copy of the City’s emerald ash borer response plan with a map of the City’s ash trees, as well as information about ash tree identification, emerald ash borer symptoms, removal of trees in the right of way, homeowners’ responsibilities, tree selection, and frequently asked questions are available at www.coralville.org/emeraldashborer.
