Trees in Trouble-Sudden Oak Death...On the Move


Activity Description: 

Students will observe and discuss photos and information sheets on symptoms of SOD and how the pathogen spreads.  A hands-on activity demonstrating how soil is moved on shoes follows, and is wrapped up with a discussion on sanitizing practices.
