Invasion by alien plant species represents a challenge to land managers throughout the world as they attempt to restore frequent fire-adapted ecosystems following decades of fire exclusion. In ponderosa pine Pinus ponderosa forests of western North…

This report intends to increase the accuracy of cost data available for planning and prioritizing fuel management in national forests. A survey of fire management officers was used to develop regression models that may be used to estimate the cost…

ANNOTATION: The potential for biomass utilization to enhance the economics of treating hazardous forest fuels was examined on the Bitterroot National Forest and surrounding areas. Initial forest stand conditions were identified from Forest Inventory…
Year Published:
The bird species in western North America that are most restricted to, and therefore most dependent on, severely burned conifer forests during the first years following a fire event depend heavily on the abundant standing snags for perch sites, nest…
Year Published:
Erosion in the first year after a wildfire can be up to three orders of magnitude greater than the erosion from undisturbed forests. To mitigate potential postfire erosion, various erosion control treatments are applied on highly erodible areas with…

Bromus carinatus var. carinatus, Bromus carinatus var. marginatus (California brome, mountain brome)
This FEIS species review synthesizes information on the relationship of Bromus carinatus var. carinatus, Bromus carinatus var. marginatus (California brome, mountain brome) to fire--how fire affects the species and its habitat, effects of the…
Year Published:
The relative behavior of surface-crown fire spread rate modeling systems used in three fire management applications-CFIS (Crown Fire Initiation and Spread), FlamMap and NEXUS- is compared using fire environment characteristics derived from a dataset…
Year Published:
Assessment of crown fire potential requires quantification of canopy fuels. In this study, canopy fuels were measured destructively on plots in five Interior West conifer stands. Observed canopy bulk density, canopy fuel load, and vertical profiles…
Year Published:
Preliminary estimates of harvesting costs for forest fuel reduction treatments in the West are presented. Cost estimates were made for typical stands based on Forest Inventory and Analysis (FIA) plots that represented forest stands in 12 western…

This FEIS species review synthesizes information on the relationship of Rosa woodsii (Wood's rose) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management considerations.…
Year Published:
This FEIS species review synthesizes information on the relationship of Calypso bulbosa (fairy slipper) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management considerations.…
Year Published:
Ponderosa pine is one of the most widely distributed tree species in western North America. It is highly-valued as a source of lumber, but also is key to the health and social value western forests, whether growing in pure stands or in mixture with…

Evaluation of post-wildfire debris flow mitigation methods and development of decision-support tools
In this study we analyzed the effectiveness of erosion control treatments in reducing post-fire debris-flow volume. We used detailed surveys of series channel cross sections in 46 basins in Colorado, Utah and California to develop graphs of the…

This FEIS species review synthesizes information on the relationship of Vulpia myuros (rattail sixweeks grass) to fire--how fire affects the species and its habitat, invasiveness of the species, effects of the species on fuels and fire regimes, and…
Year Published:
Multiple entries into forest stands are often needed for fire hazard reduction and ecosystem restoration treatments in the Inland Northwest U.S.A. region. However, soil compaction occurring from mechanized harvesting operations often remains for…
Year Published:
In this paper we discuss four principles identified through recent research for effective citizen-agency communication and examine their use in accomplishing fire management objectives. Principles include the following: (1) effective communication…
Year Published:
Fire is a primary natural disturbance in most forests of western North America and has shaped their plant and animal communities for millions of years. Native species and fundamental ecological processes are dependent on conditions created by fire.…
Year Published:
A primary goal in the management of forests and grasslands is to maintain community structure and disturbance processes within their historical range of variation. If, within a managed ecosystem, either is found to lie outside that range,…
Year Published:
Adequate and reliable erosion prediction tools are needed for sound forest resources management. Numerous watershed models have been developed during the past. These models, however, are often limited in their applications largely due to their…

This research effort is designed to investigate effectiveness of burn severity mapping, using differenced Normalized Burn Ratio (dNBR) for ecosystem monitoring at the 30m scale. The hypothesis of our research is that the differenced normalized burn…
