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.
Learn to identify trees in winter, by their twigs and other features, with this key to native and commonly introduced deciduous trees of the U.S. and Canada east of the Rockies.--Information taken from back of book.
The correspondence includes circular letters and exchanges between the Extension Forester and the Director of the Extension Service, as well as the County Extension Agents. Correspondence from outside the University and from private forestry organizations and extension service agencies in other states is also in the series. Of special interest in the correspondence of Charles Ross are references to the issue of national population control and growth. The educational programs were administered by Forestry Extension and constitute short courses and forest conservation tours for school children. The research projects, undertaken by Forestry Extension from the 1960s through the 1980s, relate mostly to the impact of forests and lumbering upon streams and rivers; one major project pertains to the Alsea Basin. The Informational Files cover forest related topics such as camping and the outdoors, sawmills and lumbering equipment, and forestation. The Survey Report offers a summary of the effectiveness of Forestry Extension programs in Oregon. Series VIII contains correspondence, a report, and returned questionnaires relating to the development by the Extension Service of contract services for woodland properties. The situation studies primarily address options in land use including forestry co-ops and recreational use of private farm and woodlands. Series X covers program planning topics such as a long range farm forestry plan and includes county planning council recommendations, group process guides, and plan of work reports. The training materials relate to the informational role of extension agents and forestry education in secondary schools and include correspondence, memoranda, and reports.
