Wildland-urban interface (W-UI) fires are a significant concern for federal, state, and local land management and fire agencies. Research using modeling, experiments, and W-UI case studies indicates that home ignitability during wildland fires depends on the characteristics of the home and its immediate surroundings. These findings have implications for hazard assessment and risk mapping, effective mitigations, and identification of appropriate responsibility for reducing the potential far home loss caused by W-UI.

Web site and CD-ROM include 21 pages of text plus electronic data for 55 succession sites including color plates, tables, and figures. Provides data on quantitative postfire changes of plant species and forest vegetation components for up to the first 25 years of secondary plant succession for 55 forest sites in northern Idaho and northwestern Montana. Cover (aerial crown) and volume (aerial crown space occupied) data are presented as percent cover (m 2 /0.01 ha) and m 3 /0.01 ha to permit their direct application to the wide range of wildland management problems involving early postfire...

This annotated bibliography contains 1,905 citations from professional journals, symposia, workshops, proceedings, technical reports, and other sources. The intent of this compilation was to: (1) assemble, to the extent possible, all available and accessible publications relating to riparian management within a single source or document; (2) provide managers, field biologists, researchers, and others, a point of access for locating scientific literature relevent to their specific interest; and (3) provide, under one cover, a comprehensive collection of annotated publications that could...

The purpose of this conference was to increase awareness through exploration and evaluation of global, national, and regional perspectives about the potential contributions that watershed management can make to the conservation, sustainable development, and use of natural resources in ecosystem-based land stewardship in the 21st century. The conference consisted of 2 and a half days of synthesis papers. These papers were presented in plenary sessions and prepared by invited speakers from public and private research, management, and educational organizations. Over 50 poster papers complement...

Although the Wilderness Act of 1964 was justified in part by the importance of aquatic conservation, implementation of the Act has primarily focused on protecting terrestrial ecosystems. In this paper, we investigated the role of Congressionally-designated wilderness towards conservation of aquatic biointegrity in western Montana. To evaluate trends between 6th code watersheds (“subwatersheds”) with and without wilderness, we applied a previous Aquatic Diversity Areas (ADA) analysis which scored subwatersheds for indicators of aquatic biointegrity and conservation significance: road...

State-of-the-environment reporting is used by organizations to inform people about the status of natural resources and health of ecosystems, to recognize and respond to changing environmental conditions and to help citizens better understand their relationship with the ecosystems in which they live and work. The status of wilderness is an important part of state-of-the-environment reporting. Recent opinion polls and consultations on Crown land use planning have confirmed that Ontarians value wilderness and remain concerned about its future. This paper reviews the history of wilderness...

We estimate number of tree species in National Forest populations using the nonparametric estimator. Data from the Current Vegetation Survey (CVS) of Region 6 of the USDA Forest Service were used to estimate the number of tree species with a plot close in size to the Forest Inventory and Analysis (FIA) plot and the actual CVS plot for the 5.5 km FIA grid and the 2.7 km CVS grid.

FireWorks is an educational program for students in grades 1-10. The program consists of the curriculum in this report and a trunk of laboratory materials, specimens, and reference materials. It provides interactive, hands-on activities for studying fire ecology, fire behavior, and the influences of people on three fire-dependent forest types - Pinus ponderosa (ponderosa pine), Pinus contorta var. latifolia (interior lodgepole pine), and Pinus albicaulis (whitebark pine). Wildland fire provides a rich context for education because it promotes understanding and integration of numerous...

The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) has been developed to assess the risk, behavior, and impact of fire in forest ecosystems. This extension to the widely-used stand-dynamics model FVS simulates the dynamics of snags and surface fuels as they are affected by stand management (of trees or fuels), live tree growth and mortality, and fires. It offers all the standard silvicultural options available in FVS as well as various fuel treatments and prescribed burns. In addition to the standard output provided by FVS, the FFE produces indicators of snag size...

Sustainable development, ecosystem management and ecosystem health are three prominent catch phrases that now permeate the scientific and popular media, and form the basis of a growing number of private sector, government and academic programs. This discussion paper briefly explores the definition and application of these concepts as a context for wilderness protection programs by arguing that the idea of “sustainable living” is preferred over “sustainable development” as a vision for the future, an ecosystem approach to management is one method by which sustainable living might be...
