Description: The Western Root Disease Model as it currently exists is described, and the assumptions that were made to adapt the model to simulate attack by Heterobasidion annosum in coniferous forests of south-central Oregon are defined. Some simulations produced by this adapted model are presented to stimulate provocative discussion, thought, and action. These simulations indicate that with no action, or with continued improper management, annosus root disease will severely reduce timber yields in affected stands of true fir. Coupled with other information, this exercise provides a framework from which to build an annosus variant of the Western Root Disease Model.
