Sula Study Revisited: 20-Year Post-Fire Regeneration In The Southern Bitterroot Valley, Montana., Luke Alan Rymniak
Graduate Student Theses, Dissertations, & Professional Papers
In the summer of 2000, a number of large fires burned in the southern Bitterroot Valley near Sula, Montana. Research was conducted in 2001 and 2003 in the fire-affected areas of the French Basin and Larid Creek areas in order to investigate the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration. In 2020 these areas were remeasured to understand trends over time by evaluating the impact of these same factors 20 years post fire. The results showed that the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration were varied. The most influential …
Collaborative Conservation And Backcountry Weed Control: A Case Study Of The Great Burn Proposed Wilderness,

Collaborative Conservation And Backcountry Weed Control: A Case Study Of The Great Burn Proposed Wilderness, Christopher James Prange
Graduate Student Theses, Dissertations, & Professional Papers
Noxious weeds have become a management priority on public lands in the United States. Managing invasive weed populations in natural areas with complex ecosystems presents issues that need a systems-wide approach over long temporal and spatial scales. This broad-scale problem increasingly demands collaborative efforts. While collaborative conservation has become a tool in natural resource management during the 21st century, it is less commonly applied in weed control in backcountry wilderness areas. Programs that have been initiated are understudied. Accordingly, this research was conducted through semi-structured interviews to gather perspectives of weed professionals involved in a collaborative backcountry weed program …
Effects Of Prescribed Fire On Drought Resistance And Recovery In Mixed Conifer Forests Of Lassen Volcanic National Park, California,

Effects Of Prescribed Fire On Drought Resistance And Recovery In Mixed Conifer Forests Of Lassen Volcanic National Park, California, Zachary J. Wenderott
Cal Poly Humboldt theses and projects
Forests throughout much of the western United States are experiencing increasing climatic variability, often resulting in decreased forest productivity and elevated likelihood of tree mortality. Severe drought, such California’s recent 2012-2015 drought, are projected to increase in intensity, frequency, and severity throughout much of this region in coming years. Forest management has long relied on prescribed fire and mechanical thinning to reduce fuel loads and ameliorate potential fire hazards. These treatments may also have the ability to reduce stand density, alleviate competitive pressures, and allow residual trees access to critical resources during periods of extreme stress. Utilizing a long-term National …
The Politics Of Biomass Energy In California: How External Benefits Are Used To Support An Economically Marginal Sector,

The Politics Of Biomass Energy In California: How External Benefits Are Used To Support An Economically Marginal Sector, Dana L. Dysthe
Cal Poly Humboldt theses and projects
Since the 1990s, there has been a decline in biomass energy generation in California. In order to promote state governmental policies aiming to increase biomass energy generation in California, the sector has been linked to a series of external benefits that biomass energy purportedly brings. Through document analysis, semi-structured interviews, and participant observation, five distinct external benefits were identified that have been used to promote the biomass energy sector. These external benefits are: renewable energy generation, air quality improvements, promotion of forest restoration and fuel removal projects, disposal of wood waste from agricultural and forestry sectors, and rural economic development. …

Recreation, Vegetation Management, And Disease Impact Sympatric Carnivore Activity In California's East Bay Parks, Leigh J. Douglas
Cal Poly Humboldt theses and projects
East Bay Regional Park District designated over 1000 ha of protected wildland-urban interface habitat in the hills of California’s East Bay Area for invasive tree removal to reduce fire risk and restore native habitat over a 10-year period starting in 2016. From June to November 2019, 36 camera traps were deployed using a stratified two-pronged detection approach of surveying recreation and wildlife trails to assess the impact of vegetation management on the spatiotemporal distribution of sympatric carnivore species while accounting for potential impacts of human activity and proximity to development. The sampling effort resulted in 5,191 cumulative trap nights, 2,739 …
Regeneration Patterns In Silvicultural Openings Of Western Great Lakes Northern Hardwood Forests 15-24 Years Post-Harvest,

Regeneration Patterns In Silvicultural Openings Of Western Great Lakes Northern Hardwood Forests 15-24 Years Post-Harvest, Matthew S. Vandermolen
Dissertations, Master's Theses and Master's Reports
In managed northern hardwood forests, successful forest regeneration can depend on the application of silvicultural methods tailored to stand-specific recruitment limitations. The objective of this research is to develop a deeper understanding of the factors that interfere with tree regeneration at three long-term, well-replicated experimental canopy gap studies in the upper Great Lakes region, USA. Chapter 2 examines regeneration at a hemlock canopy gap study 18 years post-harvest that included deer exclosures and a gradient of gap sizes. Chapter 3 investigates the spatial patterns of low-density regeneration along gradients of gap size and different levels of legacy-tree retention at two …
Evaluating Long-Term Growth And Yield In Upper Great Lakes Region Northern Hardwoods Cutting Trials,

Evaluating Long-Term Growth And Yield In Upper Great Lakes Region Northern Hardwoods Cutting Trials, Maeve Draper
Dissertations, Master's Theses and Master's Reports
Common partial cutting management methods in Lake States hardwoods include both selection management and diameter-limit cuttings. Single-tree selection in particular is a widely prescribed silvicultural system in northern hardwoods and has an established history of use throughout the entire range of the forest type. Using data from two historic silvicultural studies, long-term comparison of single-tree selection methods and other partial cutting practices in northern hardwoods reveals that single-tree selection to higher residual basal areas, as widely applied in Great Lakes northern hardwood forests, is inferior using financial and volume yield criteria. Alternatives that remove more of the larger trees appear …
