More than 100 Oak trees in Sunset Woods Park were treated this fall to protect against damage caused by the Twolined Chestnut Borer. This treatment should provide two-year protection for vulnerable trees.
Oak trees become susceptible to damage from the Chestnut Borer beetle when tree vigor is reduced by drought and/or other diseases. Infested oaks can die after 2 to 3 years of infestation. The District has worked with tree care experts to identify at-risk trees for treatment.
