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.

The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.

The COVER extension to the Stand Prognosis Model predicts tree canopy closure, crown volume, crown profile area, and foliage biomass within vertical height classes, and the probability of occurrence, height, and cover of shrubs in forest stands. The model may be used to produce a descriptive summary of a stand at the time of inventory, or to project overstory and understory characteristics through time for natural and managed stands. This paper documents use of the COVER program, an adjunct to Version 5.0 of the Prognosis Model. Preparation of input, interpretation of output, program control, and model characteristics are described. Potential applications of COVER estimates to wildlife, hydrology, and insect pest modeling are presented.

Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
