Assessing Post-Fire Revegetation Efforts In Box Elder County, Utah, Using The Rangeland Analysis Platform, Rayce Bryan
Assessing Post-Fire Revegetation Efforts In Box Elder County, Utah, Using The Rangeland Analysis Platform, Rayce Bryan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
After fires occur in western rangelands, land management agencies commonly perform vegetation treatments and reseeding projects. The West Box Elder Coordinated Resource Management Group expressed concern regarding the difficult process of determining outcomes from the many post-fire revegetation projects undertaken on rangeland of Box Elder County, Utah. This research attempted to compile and clarify the fire and treatment history of the county and produce an assessment of the outcomes from each unique post-fire treatment in West Box Elder County. Also produced was a database of post-fire revegetation outcomes in published literature.
Unique treatment polygons were identified and then subset according …

Hosting Flame Cap Biochar Kiln Workshops To Teach Hazardous Fuel Reduction, Darren Mcavoy, Michael R. Kuhns, Megan Dettenmaier, Lauren Nicole Dupéy
Extension Research
The combination of large volumes of woody fuel needing disposal after forestry activities and evolving regulatory restrictions makes traditional methods of pile burning increasingly difficult. Alternatively, using small kilns to pyrolyze these fuels on-site yields a potentially valuable product: biochar. In this article, we describe an educational program on the use of small kilns for fuel treatment and biochar production. Survey results from our series of demonstrations indicate that 69% of respondents added biochar to their soils and 100% of respondents increased their interest in biochar. Moreover, we reduced hazardous fuel in Utah by more than 20 semitruck loads by …

The 55 JFSP plots were established to capture forest types, fire histories, and severity levels beyond those found within the YFPD. The plots were square 50 m × 50 m plots established in Pinus ponderosa, Pinus jeffreyi, and Abies concolor – Pinus lambertiana forest types between 1,431 m and 2,250 m elevation. Plots were installed post-fire based on a randomly chosen locations stratified by burn severity levels as calculated from the differenced Normalized Burn Ratio (dNBR). For details on site selection see Furniss et al. (in review). In the field, plots were located using a handheld GPS and …
Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane Mckenna
Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane Mckenna
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Forest Inventory and Analysis (FIA), the United States’ forest census, measured sixty-six Mexican spotted owl nest stands in order gain insight into the structure and composition of the nest habitat of this threatened species. I used these data, along with the greater FIA database and the Forest Vegetation Simulator to explore questions surrounding the management of Mexican spotted owl habitat, specifically how to balance the objective of sustaining and enhancing nest habitat in face of increasing forest fire size and severity in the Southwest. My research consisted of three studies. The first study quantified the structure and composition of …

Human–Wildlife Interactions
Free-ranging or feral horses (Equus ferus caballus) were important to the livelihood of First Nations and indigenous communities in Canada. The early inhabitants of the boreal region of British Columbia (BC) capitalized on naturally occurring wildfires and anthropogenic burning to provide forage for free-ranging horses and manage habitat for wildlife. This form of pyric herbivory, or grazing driven by fi re via the attraction to the palatable vegetation in recently burned areas, is an evolutionary disturbance process that occurs globally. However, its application to manage forage availability for free-ranging horses has not been studied in northern Canada. Across Canada, there …
The Role Of Fire In Aspen Ecology And Restoration, Douglas J. Shinneman, Kevin D. Krasnow, Susan K. Mcilroy
The Role Of Fire In Aspen Ecology And Restoration, Douglas J. Shinneman, Kevin D. Krasnow, Susan K. Mcilroy
Aspen Bibliography
Quaking aspen is generally considered to be a fire-adapted species because it regenerates prolifically after fire, and it can be replaced by more shade-tolerant tree species in the absence of fire. As early-successional aspen stands transition to greater conifer-dominance, they become increasingly fire prone, until fire returns, and aspen again temporarily dominate. While this disturbance-succession cycle is critical to the persistence of aspen on many landscapes, some aspen stands persist on the landscape without fire. The complex role of fire is an important consideration for developing conservation and restoration strategies intended to sustain aspen.
Bark Beetle-Induced Changes To Crown Fuel Flammability And Crown Fire Potential, Wesley G. Page
Bark Beetle-Induced Changes To Crown Fuel Flammability And Crown Fire Potential, Wesley G. Page
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Recent outbreaks of aggressive tree-killing bark beetles, including mountain pine beetle in lodgepole pine forests and spruce beetle in Engelmann spruce forests, have recently affected vast areas across western North America. The high levels of tree mortality associated with these outbreaks have raised concerns amongst fire managers and wildland firefighters about the possible effects on fire behavior potential, particularly crown fire potential, as crown fires (fires that consume part or all of tree crowns) hinder the ability of firefighters to conduct safe and effective fire suppression operations. The purpose of this research was to measure and characterize the changes in …
Silviculture Certification Revalidation Case Studey : An Assessment Of Aspen Regeneration By Fire Intensity Following Prescribed Burning On Low Productivity Sites In Southwest Idaho And/Or A Simplistic Model Showing Aspen Sprouting Response By Varying Degrees Of Fire Intensity As Defined By Degree Of Aspen Crown-Kill Within The Lime Creek Aspen Restoration Project Area, Steven L. Williams
Aspen Bibliography
This Case Study is prepared for revalidation as a certified silviculturist in the Intermountain Region. When I first began working on this study, I anticipated that prescribed fire would produce variable degrees of aspen crown-kill and that differences in aspen sprouting would exist across the project area. What I observed was that although variable degrees of aspen crown-kill do exist, their distribution and relative amounts is more a function of prescribed fire ignition than of vegetation conditions. Very nearly full aspen crown-kill occurs with any fire that sustains itself enough to carry through the vegetation. Where prescribed fire is employed, …

Forage Quality In Burned And Unburned Aspen Communities, N.V. Debyle, P.J. Urness, D.L. Blank
Aspen Bibliography
We assessed the effects of fire on the quality of herbaceous and browse forage for elk (Gervus e/aphus) and domestic sheep in the aspen (Populus tremu/oides) forest type. Selected forage species were sampled on burned and adjacent unburned areas during the summers of the first and second years after autumn prescribed burning of three sites in southeastern Idaho. These samples were analyzed for in vitro dry matter digestibility (IVDMD), crude protein, calcium, and phosphorus. This aspen type has a highly nutritious understory irrespective of burning. We found additional improvement in forage quality as a result of prescribed burning. In the …
Fire Frequency And The Vegetal Mosaic Of The Utah State University Experimental Forest, Linda L. Wadleigh-Anhold
Fire Frequency And The Vegetal Mosaic Of The Utah State University Experimental Forest, Linda L. Wadleigh-Anhold
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A fire history study conducted for the Utah State University (USU) Experimental Forest using three distinct periods of fire frequency, historic (1700-1855), settlement (1856-1909), and suppression (1910-present), showed a decreased mean fire interval (MFI) during the settlement period and a greatly increased MFI during the suppression era. The difference was attributed to the influx of ignition sources during the settlement of the nearby Cache Valley, located 40 kilometers to the west. The interaction of settlers with the resource during logging and livestock grazing activities encouraged the high MFI and created the vegetal mosaic now observed on the study area.
