DescriptionPort-Orford-cedar (POC) (Chamaecyparis lawsoniana) is limited in its natural range to southwest Oregon and northwest California. It is highly susceptible to the introduced root pathogen, Phytophthora lateralis, which causes a fatal root disease throughout most of its range. The disease is transmitted by movement of infested soil and water and is most common along stream courses and roadsides. Trees killed by the disease typically turn vivid reddish brown, which provides a good aerial signature.
