Forecasting Fine Fuels In The Intermountain West Rangelands, Mira Ensley-Field May 2022

Forecasting Fine Fuels In The Intermountain West Rangelands, Mira Ensley-Field

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this thesis project was to develop a fine fuels forecast to help fire managers anticipate spatial variation in fuel loads before the start of the fire season. In Chapter 1 we compile and analyze the methodologies of the historical record of fine fuel loads reported to the Great Basin Coordination Center. Based on our data analysis, we developed a series of recommendations for improving the methods used to sample fine fuels in the future as well as more broad ideas for how land managers can use emerging technologies to more effectively monitor fine fuels. In Chapter 2, …


Long‐Term Effects Of Tree Expansion And Reduction On Soil Climate In A Semiarid Ecosystem, Bruce A. Roundy, R. F. Miller, R. J. Tausch, J. C. Chambers, B. M. Rau Sep 2020

Long‐Term Effects Of Tree Expansion And Reduction On Soil Climate In A Semiarid Ecosystem, Bruce A. Roundy, R. F. Miller, R. J. Tausch, J. C. Chambers, B. M. Rau

Articles

In sagebrush ecosystems, pinyon and juniper tree expansion reduces water available to perennial shrubs and herbs. We measured soil water matric potential and temperatures at 13–30 and 50–65 cm soil depths in untreated and treated plots across a range of environmental conditions. We sought to determine the effects of tree expansion, tree reduction treatments, and expansion phase at time of treatment over 12–13 yr post‐treatment. Because the effects of tree reduction on vegetation can vary with the soil temperature/moisture regime, we also analyzed differences in soil climate variables between the mesic/aridic‐xeric and frigid/xeric regime classifications for our sites. Growing conditions …


Fuels Guide For Sagebrush And Pinyon-Juniper Treatments: 10 Years Post-Treatment, Samuel S. Wozniak, Eva K. Strand Oct 2019

Fuels Guide For Sagebrush And Pinyon-Juniper Treatments: 10 Years Post-Treatment, Samuel S. Wozniak, Eva K. Strand

Reports

Increased woody plant dominance and degraded understory vegetation are important issues on rangelands in the Intermountain West. Land managers implement woody plant reduction treatments of sagebrush (Artemisia spp.), juniper (Juniperus spp.), and pinyon pine (Pinus spp.) to increase understory diversity and cover, restore wildlife habitat, increase forage, improve ecosystem functions, and reduce or manipulate fuels to increase ecosystem resilience to fire and resistance to invasive annual grasses. Woody plant reduction treatments alter fuel orientation, continuity, and loading, and therefore have important implications for wildfire behavior, effects, and management. Currently, there is a lack of knowledge of the longer-term implications of …


Guide For Quantifying Fuels In The Sagebrush Steppe And Juniper Woodlands Of The Great Basin, Andrea Stebleton, Stephen Bunting Jan 2009

Guide For Quantifying Fuels In The Sagebrush Steppe And Juniper Woodlands Of The Great Basin, Andrea Stebleton, Stephen Bunting

Reports

Prescribed fire is increasingly used for fuels management and ecosystem restoration. Managers and fuels specialists of the Great Basin are often required to estimate fuel loadings to predict fire behavior, recommend fuel treatments, or restore an area to its natural fire regime. Because of invasive species and woodland encroachment, there have been extensive changes in the fire regimes of sagebrush steppe over the past 150 years. After two years of pre-treatment sampling across six states of the Great Basin, the Sagebrush Steppe Treatment and Evaluation Project (SageSTEP) measured many variables including vegetation, soils, hydrology, wildlife, and fuels. These data will …

Fire Behaviour In Aspen Slash Fuels As Related To The Canadian Fire Weather Index, M.E. Alexander Jan 1982

Fire Behaviour In Aspen Slash Fuels As Related To The Canadian Fire Weather Index, M.E. Alexander

Aspen Bibliography

The characteristics and short-term results of experimental prescribed fires in 2-year-old trembling aspen (Populus tremuloides Michx.) logging slash in northern Minnesota have been described by D. A. Perala (1974. Can. J. For. Res. 4: 222-228). The associated burning conditions are expressed here in terms of the weather-dependent numerical fuel moisture codes and fire behavior indexes of the Canadian system of forest fire danger rating.
