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.
The activity will demonstrate how humans can unknowingly assist in moving the pathogen to unaffected areas and how we can help stop this spread.
Visit the California Oak Mortality Task Force website (http://www.suddenoakdeath.org) for more information about SOD and Phytophthora ramorum, as well as to obtain photographs and pamphlets to use in the following activities.
