Book Description
We present the history of land use and historic vegetation conditions on the Sacramento Ranger District of the Lincoln National Forest within the framework of an ecosystem needs assessment. We reconstruct forest vegetation conditions and ecosystem processes for the period immediately before Anglo-American settlement using General Land Office survey records, historic studies and accounts, and reconstructive studies such as dendrochronological histories of fire and insect outbreak and studies of old growth. Intensive grazing, clearcut logging, fire suppression, and agriculture in riparian areas have radically altered forest structure and processes since the 1880s, when intensive settlement began in the Sacramento Mountains. Present forests are younger and more dense than historic ones, and in areas that were previously dominated by ponderosa pine, dominance has shifted to Douglas-fir and white fir in the absence of frequent surface fire. Landscapes are more homogeneous and contiguous than historic ones, facilitating large-scale, intense disturbances such as insect outbreaks and crown fires.

Book Description
We report the results of a questionnaire and workshop that sought to gain a better and deeper understanding of the contemporary information needs of wildland fire and fuels managers. Results from the questionnaire indicated that the decision to suppress a wildland fire was most often influenced by factors related to safety and that the decision to allow a fire to burn was influenced by a variety of factors that varied according to land management objectives. We also found that managers anticipated an increase in the use of wildland fire, but that these increases will be moderate due to a variety of constraints that will continue to limit the use of wildland fire. From the workshop, we learned that managers will need to become increasingly strategic with their fire and fuels management planning, and that the information used to support tactical fire operations may prove to be insufficient. Furthermore, the managers participating in the workshop indicated the functional linkage between land management and fire management planning is lacking. We suggest that effective fire management planning requires information on the benefits and risks to a wide variety of values at landscape scales, integration with land management objectives, and a long-term perspective.
