Effect of Armillaria spp. or Phellinus weirii on stand dynamics are represented by the Western Root Disease Model. This model, which operates in conjunction with the Prognosis Model for Stand Development, can be used to evaluate effects of a wide assortment of silvicultural practices, including stump removal for disease reduction. The model was developed through a series of workshops designed to elicit information about the disease process from many experts on the biology of the root diseases and their hosts. Forest land managers also participated in the workshops to provide their insight into the values and resources being affected. This publication contains model applications, a brief description of how the model is formulated, and documentation of the keyword procedures for using the model.

The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behavior over time, in the context of stand development and management. Existing models of fire behavior and fire effects were added to FVS to form this extension. New submodels representing snag and fuel dynamics were created to complete the linkages. This report contains four chapters. Chapter 1 states the purpose and chronicles some applications of the model. Chapter 2 details the model's content, documents links to the supporting science, and provides annotated examples of the outputs. Chapter 3 is a user's guide that presents options and examples of command usage. Chapter 4 describes how the model was customized for use in different regions. Fuel managers and silviculturists charged with managing fire-prone forests can use the FFEFVS and this document to better understand and display the consequences of alternative management actions.
