Description: We are working to evaluate risks associated with human spread of the sudden oak death (SOD) pathogen, Phytophthora ramorum, to currently uninfested areas in California. Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murray) Parl.) root disease (POC RD), caused by Phytophthora lateralis, has brought awareness that pathogens can be moved in forest settings by materials adherent to vehicles and equipment. Discovery of this human vector prompted P. lateralis control measures with notable social and economic costs, such as road closures, vehicle and equipment washing requirements, and standards for sanitizing drafted water.

Keywords: Sudden oak death, Phytophthora ramorum, invasive species, tanoak, Notholithocarpus densiflorus, coast live oak, Quercus agrifolia, Japanese larch, Larix kaempferi
