The city of South Portland has released its plan for dealing with a harmful invasive species.

Emerald Ash Borer, according to the Maine Forest Service, is a metallic green beetle whose larvae damages ash trees.

South Portland officials say they plan to treat or remove the trees that have been affected. Trees that will be removed will be replaced by another tree that is likely to thrive.

The $30,000 cost for this year will be covered by South Portland’s American Rescue Plan Act funds. The full cost, timeline and overall project will be determined once there’s been a full assessment of the situation, officials said.

The city advises residents to look for the signs of emerald ash borer, including the splitting of bark, sprouts growing from the roots or trunk of a tree and small holes shaped like the letter “D” in the tree.

Anyone who suspects the presence of an emerald ash borer in a city ash tree should contact the city arborist.
