Abstract

Information about the biology, diseases, and management of Port-Orford- cedar was collected from the literature, from unpublished research data of the authors and the USDA Forest Service, conversations with personnel involved in all facets of Port-Orford-cedar management, and visits to stands throughout the range of the species. Information is summarized and presented regarding species characteristics, distribution, environment, vegetation, autecology, usage, past management, and the biology and effects of the most important pathogen. Recommendations for managing the species in the presence of this pathogen, Phytophthora lateralis, were developed. Presence of this introduced pathogen will complicate the management of Port-Orford-cedar and somewhat reduce the area where it can be grown, but production of future crops of cedar should be possible given careful, consistent application of the guidelines presented.
