Sawtooth oak, a tree native to eastern Asia, is popular for use in street tree plantings due to its interesting foliage and fruits (acorns). It spreads by seed that is produced in large numbers and has been found in recent years to be escaping from plantings to become invasive in wild areas, displacing native plants. Because of this, land managers recommend against the use of sawtooth oak and suggest instead that landscapers use native oaks, of which there are many species to choose.

Prevention and Control
Do not plant sawtooth oaks. If small, pull seedlings or treat leaves with glyphosate. To control large trees: cut tree and grind stump; girdle, hack and squirt glyphosate; or cut and paint stump with glyphosate.

Native Alternatives
shagbark hickory (Carya ovata), American beech (Fagus grandifolia), green ash (Fraxinus pennsylvanica), red oak (Quercus rubra)
