Problem Plant: Sawtooth Oak

Sawtooth Oak (Quercus acutissima)        

This native of eastern Asia was introduced in 1862 as an ornamental and gained
favor during the past 50 years as a street tree and a source of food for small game
such as turkeys. Its rapid growth allows it to out-compete native oaks, and the
dispersal by animals of its numerous acorns has caused it to become a problem
invasive species in forests along the east coast.
