Emerald Ash Borer
What is Emerald Ash Borer?
The Emerald Ash Borer (EAB) is a small, green boring insect that attacks and kills all trees in the Ash family (Fraxinus spp). This invasive insect has been spreading across the State of Wisconsin for the last ten years and is firmly entrenched in River Falls. About 20 percent or 1900 of our public trees in River Falls are Ash
What does it mean if I received an orange EAB door hanger and have a white dot spray painted on the tree?
The Ash in your boulevard is seriously infected and beyond treatment or saving. EAB infected trees quickly become hazardous because of dropping limbs and the entire tree falling over.
What's the plan for the tree and future space?
The City’s tree contractor will remove the tree soon after the doorhanger arrival. The stump will be ground and the area rehabbed as soon as possible. The City will then identify a space in the boulevard to replant a new tree.
