Emerald Ash Borer (EAB)

The emerald ash borer (EAB) is an Asian insect pest that are fatal to ash trees. There are approximately 2,000 ash trees on public property either in parks or in right-of-ways within Iowa City.

The City will not examine or determine a course of action for any trees on private property unless those trees have become dangerous or hazardous. For more information on the City's tree ordinance, view the City Code.

If a tree is exhibiting EAB symptoms, contact the Iowa Department of Agriculture and Land Stewardship State Entomologist at 515-725-1470 or

If you have a tree that is not exhibiting symptoms of EAB, but would like your tree to be evaluated, contact a certified arborist.

Tree Inventory 

In 2016 and 2017, a team of arborists from Plan-It Geo, a geotechnical firm from Colorado, conducted a tree inventory, gathering data on the City's urban forestry, as well as mapping and cataloging the tree species. This inventory will yield information and mapping tools to help the Parks and Forestry Division better manage and maintain Iowa City's urban forest.
