Twentieth century fire patterns were analyzed for two large, disparate wilderness areas in the Rocky Mountains. Spatial and temporal patterns of fires were represented as GIS-based digital fire atlases compiled from archival Forest Service data. We…

Our experience testing ecosystem-based management (EM) treatments in ponderosa pine (Pinus ponderosa)/fir (Abies spp.) is summarized here. Topics covered include silvicultural treatments, fire application, soils and nutrient considerations, wildlife…

This FEIS species review synthesizes information on the relationship of Ceanothus sanguineus (redstem ceanothus) to fire--how fire affects the species and its habitat, and fire management considerations. Information is also provided on the species…
Year Published:
Management activities are analyzed at landscape scales employing both simulation and optimization. SIMPPLLE, a stochastic simulation modeling system, is initially applied to assess the risks associated with a specific natural process occurring on…
Year Published:
Fuels burned by either prescribed or wildfires are complex and important components of forested ecosystems. Fine fuels consisting of fallen limbs, twigs, and leaves of shrubs and trees are rich in nutrients. If these fuels are not immediately burned…

The status of sage grouse populations and habitats has been a concern to sportsmen and biologists for >80 years. Despite management and research efforts that date to the 1930s, breeding populations of this species have declined throughout much of…
Year Published:
Sustainable, ecologically-based management of pine/fir forests requires silviculturists to integrate several treatments that emulate historic disturbance processes. Restoration prescriptions typically include cleaning or heavy understory thinning,…

This FEIS species review synthesizes information on the relationship of Vaccinium membranaceum (big huckleberry) to fire--how fire affects the species and its habitat, and fire management considerations. Information is also provided on the species…

This study assessed the effectiveness of FireWorks, an educational trunk about wildland fire, in increasing student understanding, enabling students to apply classroom learning in a field setting, and improving the learning environment. Students who…
Year Published:
Fire, insects, disease, harvesting, and precommercial thinning all create mosaics on Northern Rocky Mountain landscapes. These mosaics are important for faunal habitat. Consequently, changes such as created openings or an increase in heavily stocked…

Surveys of visitors to National Forests in Colorado, Idaho, and Wyoming were conducted to determine whether non-motorized recreation visitation responded to different fire ages and fire intensities. Actual and intended behavior data was combined…
Year Published:
This strategy is based on the premise that sustainable resources are predicated on healthy, resilient ecosystems. In fire-adapted ecosystems, some measure of fire use-at appropriate intensity, frequency, and time of year-should be included in…
Year Published:
Some 100 years of fire exclusion in the Interior Northwest has resulted in riparian areas dominated by dense thickets of shade-tolerant trees. If former, more open conditions could be restored, these habitats could once more support a more diverse…
Year Published:
Many of the aquatic and terrestrial ecosystems of the Pacific Northwest United States have been simplified and degraded in part through past land-management activities. Recent listings of fishes under the Endangered Species Act and major new…

A 17000 yr fire history from Yellowstone National Park demonstrates a strong link between changes in climate and variations in fire frequency on millennial time scales. The fire history reconstruction is based on a detailed charcoal stratigraphy…

This FEIS species review synthesizes information on the relationship of Pleuraphis jamesii (galleta) to fire--how fire affects the species and its habitat, and fire management considerations. Information is also provided on the species'…
Year Published:
Pinus albicaulis (whitebark pine) is an important tree species in subalpine forests of the Northern Rocky Mountains. Populations have been declining at unprecedented rates due to the introduction of an exotic pathogen and fire suppression. We…
Year Published:
One hundred years of timber harvest and reduced fire frequency have resulted in the conversion of once open stands of ponderosa pine (Pinus ponderosa) forests to dense forests dominated by Douglas-fir (Pseudotsuga menziesii). Selection harvest and…

Based on his earlier book, “Emotional Intelligence,” Goleman applies years of research to this practical guide on emotional intelligence in organizations. In the first part of the book, Goleman makes a “hard case for soft skills” by arguing that…

A broad-scale probabilistic model of forest fires, EMBYR, has been developed to simulate the effects of large fires burning through heterogeneous landscapes. Fire ignition and spread are simulated on a gridded landscape by (1) examining each burning…
