Oak trees cut down, infested by insects causing gall at school in Montgomery County

CLARKSVILLE, Tenn. (AP) — Workers have cut down about two dozen insect-infested pin oak trees at a Tennessee high school.

Northwest High School Principal Ed Stephens watched the work on Tuesday and said it was a terrible shame that the 20-year-old trees had to be felled. They were filled with horned oak gall, according to The Leaf-Chronicle.


Operations chief James Sumrell of the ClarksvilleMontgomery County School System says more trees at Minglewood Elementary school must also be removed sometime next week.

The newspaper cites a University of Kentucky website posting in reporting insecticides aren’t effective against the gall, which is caused by wasps. The only treatment is to prune the trees, which isn’t practical in large infestations. The galls eventually kill the trees.

The trees will be replaced with other varieties.
