Emerald Ash Borer in Hudson

Emerald Ash Borer (EAB) was first reported in Hudson July 10, 2018, in the commercial area along Interstate 94. EAB is a metallic green beetle that measures approximately ½ inch in length. The immature stage of the insect feeds on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Signs of EAB-infested ash trees include thinning or dying branches in the upper canopy, evidence of woodpecker activity, S-shaped feeding galleries under splitting bark, D-shaped exit holes and water sprouts along the trunk and main branches.

Please watch an interview with City Urban Forestry officials regarding the Emerald Ash Borer issue and what officials are doing to prepare for the future.
