This FEIS species review synthesizes information on the relationship of Populus balsamifera subsp. trichocarpa (black cottonwood) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire…
Year Published:
The Mortar Creek Fire burned 26 000 ha of mixed-conifer Rocky Mountain forest in July-August 1979. Changes in burn stream conditions were examined relative to reference streams for various ecological factors on two to six occasions, from October…

Vegetative regeneration of aspen can be initiated through manipulations that provide hormonal stimulation, proper growth environment, and sucker protection - the three elements of the aspen regeneration triangle. The correct course of action depends…

The paucity of aspen (Populus tremuloides) regeneration in the western United States and on Yellowstone National Park’s (YNP) northern range has been of concern to managers and scientists for much of the 20th century, with the effects of ungulate…

This FEIS species review synthesizes information on the relationship of Tetradymia canescens (spineless horsebrush) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management…
Year Published:
A variety of Forest Health and Protection treatments have been proposed to reduce long-term risks to forests from wildfire, insects, and disease. This review examines the potential effects of these treatments on sediment production in watersheds of…
Year Published:
The effects of wildfire on benthic macroinvertebrate assemblages of streams in mixed-conifer forest were examined for 10 successive years following the Mortar Creek Fire of 1979. Changes in burned-catchment streams were evaluated relative to a…

This FEIS species review synthesizes information on the relationship of Sporobolus airoides (alkali sacaton) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management considerations…

This FEIS species review synthesizes information on the relationship of Abies concolor (white fir) 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:
Wildfire alters the hydrologic response of watersheds, including the peak discharges resulting from subsequent rainfall, Improving predictions of the magnitude of flooding that follows wildfire is needed because of the increase in human population…

This FEIS species review synthesizes information on the relationship of Populus angustifolia (narrowleaf cottonwood) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management…

Uncertainty in surface-fire history: the case of ponderosa pine forests in the western United States
Present understanding of fire ecology in forests subject to surface fires is based on fire-scar evidence. We present theory and empirical results that suggest that fire-history data have uncertainties and biases when used to estimate the population…

This collection of Weick’s writings addresses a central theme of organizational sensemaking, which he defines as a means by which organizational members retrospectively make sense of situations, actions, and choices. The first part of the book…
Year Published:
Wildfire and forest operations remove vegetation and disturb forest soils. Both of these effects can lead to an increased risk of soil erosion. Operations to reduce forest fuel loads, however, may reduce the risk of wildfire. This paper presents…

This FEIS species review synthesizes information on the relationship of Ceanothus velutinus (snowbrush ceanothus) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management…

This FEIS species review synthesizes information on the relationship of Elymus elymoides (bottlebrush squirreltail) to fire--how fire affects the species and its habitat, effects of the species on fuels and fire regimes, and fire management…
Year Published:
Lewis's Woodpecker (Melanerpes lewis) has been characterized as a "burn specialist" because of its preference for nesting within burned pine forests. No prior study, however, has demonstrated the relative importance of crown-burned…
Year Published:
This article examines how eight disturbances influence forest structure, composition, and function, and how climate change may influence the severity, frequency, and magnitude of disturbances to forests. We focus on examples from the United States,…

Klein presents observations of humans acting under real-life constraints such as time pressure, high stakes outcomes, high-levels of personal responsibility, limited information, changing goals, and shifting conditions. Klein studies decision making…
