About 25% of public trees in the City are ash trees, and all ash trees are susceptible to EAB. The spread of EAB could have a devastating effect on the community.

The EAB larvae are worm-like grubs that kill ash trees by tunneling under the tree's bark. It can take up to four years after the EAB larva infests a tree before symptoms are seen. By then it is too late to save the tree.

The City will continue to work with MDA to monitor trees in the area, looking for signs of EAB.

Roseville residents who have concerns about ash trees on their property, can contact Forestry Technician Anita Twaroski at 651-792-7142. She will help property owners find resources to identify EAB and options to protect their trees. Twaroski encourages residents to talk with an arborist to identify whether there is an infestation, and what can be done to prevent an infestation. There are some preventive insecticides but there is no guarantee that they will save the tree. If a tree is infested with EAB, insecticides will not save it and it will have to be removed.

Tree removal contractors must be licensed by the City of Roseville and listed on the Tree Care Registry. Before you hire a tree removal service, call 651-792-7080 to make sure the tree service has the appropriate license.

Ash trees are often difficult to identify. The Department of Agriculture has this Guide to Ash Tree Identification to help identify whether you have an ash tree.

Because of the Emerald Ash Borer (EAB) quarantine, Ramsey County residents cannot move any hardwood species including ash trees, ash limbs, branches, logs and untreated ash lumber with the bark attached, outside of Ramsey and Hennepin counties.
