Investigating Wood Welding Parameters Using A Prototype Welding Machine, Timothy R. Melin

Master's Theses

Understanding how different processing variables influence wood welded bonds is vital if the technique will ever be used to create engineered lumber without using adhesives. A variation of vibration welding, wood welding uses pressure and friction to bond materials together. During welding, heat causes a softening in the wood, a naturally occurring composite material. This softening leads to fiber entanglement and a bond forms upon cooling.

The goal of this research was to investigate several processing aspects of the wood welding procedure. A prototype wood welding machine, designed and fabricated from the ground up, was used to investigate the effects …

Effects Of Hydrologic Gradients On Woody Debris Breakdown And Macroinvertebrate Colonization In A Cumberland Plateau Watershed, Eastern Kentucky, U.S.A., Robin Rae Bernal

Masters Theses & Specialist Projects

This research assessed the influence of hydrologic gradients on woody debris dynamics in a Cumberland Plateau watershed, eastern Kentucky, U.S.A. Although the breakdown of wood can be attributed to several different processes, including leaching, biological decay, fragmentation, and transport, the influence of differing flow regimes has been unstudied. The objectives of this study were to examine how stream channel type (temporary vs. perennial) affected wood processing dynamics (i.e., mass loss and macroinvertebrate colonization and standing stock patterns). Two questions were addressed: (1) do mass loss rates of wood differ across hydrological gradients in stream channels?, and (2) do macroinvertebrate colonization …

Bending, Like The Reed In The Wind: A System To Restore Northwestern Forests, Lisa-Natalie Anjozian

Joint Fire Science Program Briefs (2007-2012)

Silviculture is the study, cultivation, and management of forest trees. It is rooted in science, but often is an art based on the experience of the forester. This story explores free-selection, a silvicultural system developed by scientists that allows managers and stakeholders greater fl exibility in growing new forests. By using this system for applying treatments, managers craft a vision of the desired short- and long-term conditions of the forest. The focus is placed on how the remaining forest components will function, rather than focusing on stand structure guidelines that dictate stand treatments and tree removal.

Naked Eyes And Hyperspectral Images Build Fuel Maps In The Southern Appalachian Mountains, Lisa-Natalie Anjozian

Joint Fire Science Program Briefs (2007-2012)

With the limited knowledge previously available about the types of fuels, and how they are distributed in the southern Appalachian Mountains, managers have faced diffi culties in developing fi re plans for the region, including whether or where to apply prescribed fi re. For this study, the scientists took a two phase approach to determine fuel loads on the land—by ground surveys, and by remote sensing technology using hyperspectral images. Examining over 1,000 study plots in diverse topographic locations affected by various disturbances (or no disturbance) across four states, the researchers found few differences in undisturbed plots regardless of topographic …

Nature In A Name: Paulownia Tomentosa—Exotic Tree, Native Problem, Lisa-Natalie Anjozian

Joint Fire Science Program Briefs (2007-2012)

While awareness of fire’s importance in dry Appalachian forests, and the application of fire as a restoration tool have increased over the last two decades, so too has the post-fire invasion of Paulownia tomentosa (Princess tree). For the last ten years, managers have witnessed Paulownia invasion grow following fi re events. To understand this better, the team studied five life history transitions for the species: seed dispersal, seed germination, seed survival over time through incorporation in the seed bank, initial habitat requirements, and seedling persistence to maturity. Paulownia seeds were found to disperse over two miles from their source tree. …

The Northeast Washington Forestry Coalition: A Citizen-Agency Partnership That Works, Bruce Shindler

Joint Fire Science Program Briefs (2007-2012)

With the urgency of wildfi re near every community’s door, federal agencies have sought a middle ground between the extremes of timber-industry and environmental positions, one that would enable active management to reduce fuels and create safer communities. At the same time, citizen groups have organized themselves to protect important community values connected with their neighboring forests. These developments have set the stage for increasingly successful multi-stakeholder partnerships. The collaborative processes facilitated by these partnerships require considerable patience and perseverance at the outset, but the result can be a healthier forest, reduced fi re risk, more stable planning processes, and …

Filling In Knowledge Gaps In North Carolina, Elise Lequire

Joint Fire Science Program Briefs (2007-2012)

North Carolina is divided into three broad physiographic regions, from the low-lying Atlantic Coastal Plain, to the midelevation foothills—the Piedmont Plateau—to the higher elevation Blue Ridge and Appalachian zone. Understanding the behavior of fire in these widely different regions, as in much of the southeastern United States, presents challenges that differ sharply from those common in the West, where the emphasis on fire science research has been greater. An ambitious project has helped fill in local and regional knowledge gaps, as researchers gathered data and assessed the relevance and limitations of existing tools, including remote satellite sensing, weather station information, …

Sink Or Source? Fire And The Forest Carbon Cycle, Christina Frame

Joint Fire Science Program Briefs (2007-2012)

As the size and severity of fires in the western U.S. continue to increase, it has become ever more important to understand carbon dynamics in response to fire. Many subalpine forests experience stand-replacing wildfires, and these fires and subsequent recovery can change the amount of carbon released to the atmosphere because subalpine forests store large amounts of carbon. Stand-replacing fires initially convert ecosystems into a net source of carbon as the forest decomposes—a short-term effect (decades) that will likely be important over the next century if fire frequency increases as a result of climate change. Over the long term (centuries), …

The Good Earth: Run-Off, Erosion, And Recovery In The Post-Fi Re Chaparral Steeplands Of Southern California, Lisa-Natalie Anjozian

Joint Fire Science Program Briefs (2007-2012)

In September 2002, the Williams Fire burned 38,184 acres of chaparral steeplands, including more than 90 percent of the San Dimas Experimental Forest. The 1960 Johnstone Fire had burned many of the same watersheds some forty years earlier, thus providing opportunities to compare post-fire watershed response coupled with management efforts that had converted some native chaparral areas to grassland. With scant studies on soil water repellency, plant recovery, and their effects on watershed hydrology, managers face diffi culties in planning for erosion/run-off problems. The researchers delivered quantifi ed data on changing soil properties, the character and structure of regenerating plants, …

To Thin Or Not To Thin: Assessing The Consequences Of Fuel Reduction Treatments For The Non-Coniferous Ecosystems Of Southwestern Oregon, Shari Anstedt

Joint Fire Science Program Briefs (2007-2012)

Over time, fire exclusion has caused the accumulation of fuels and changes in vegetation structure and composition in many western ecosystems. This is commonly assumed to have also occurred in the oak woodlands, shrub lands and grasslands of southwestern Oregon. As a result, land managers of the Medford District of the Bureau of Land Management (BLM) have sought to reduce fuel-loads using a variety of thinning methods including mechanical mastication and hand-cutting, piling and burning. As of the mid-1990s, these treatments have been used on thousands of acres annually of the Ashland Resource Area (ARA) of the BLM. Since non-coniferous …

Using Lidar To Validate And Strengthen A Long-Range Smoke Transport Model For Air Quality Forecasting, Joy Drohan

Joint Fire Science Program Briefs (2007-2012)

Researchers have explored the potential and limitations of using lidar, the remote sensing instrument, to provide information on smoke plume dynamics and optical properties. They used a scanning lidar in the smoke-polluted atmospheres near wildfires and prescribed fires to measure the height, dynamics, and three-dimensional dispersion of smoke plumes and the temporal and spatial variations of the optical properties of the smoke particulates. The team has developed and refi ned a measurement methodology and data processing techniques for analysis of data collected from smoky atmospheres by lidar and auxiliary instruments within the smoke-polluted area. They developed, validated, and improved lidar …

Frequencies, Lasers, And Wavelengths: A Quest For Affordable, Landscape Scale Remote Sensing, Marjie Brown

Joint Fire Science Program Briefs (2007-2012)

New developments in high-resolution remote sensing systems have demonstrated the potential for generating direct, more accurate, and efficient estimates of fuels and the vegetation characteristics that influence fire behavior at the landscape scale. Two of these direct measurement tools are operated from aircraft and known by their acronyms LIDAR (Light Detection and Ranging) and IFSAR (Interferometric Synthetic Aperture Radar). IFSAR is less costly than LIDAR, and unlike LIDAR, IFSAR sees through clouds and smoke. This project sought to evaluate the utility of IFSAR data for characterizing vegetation structure in the chaparral-dominated landscapes typical over much of southern California. The researchers …

Upland Oak Regeneration, Elise Lequire

Joint Fire Science Program Briefs (2007-2012)

Along the ridgetops and in the coves of Kentucky’s Cumberland Plateau, oak forests are in a state of transition. Mature oaks still tower over the forest floor and produce acorns that provide nourishment for wildlife. Those acorns also once ensured new generations of oak from seedlings and saplings. Beneath the canopy, however, a fierce competition for light is placing the future of upland oak forests in jeopardy. Once a frequent visitor that cleared the understory, opened the canopy, and allowed sunlight to penetrate to the forest fl oor, fire has been basically absent for nearly a century. Reintroduced as part …

Exploring Patterns Of Burn Severity In The Biscuit Fire In Southwestern Oregon, Joy Drohan

Joint Fire Science Program Briefs (2007-2012)

Large wildfires are important ecologically and economically, but their behavior and effects are not well understood, especially in the Klamath-Siskiyou region, which is characterized by a diversity of conifers and evergreen sprouting hardwoods, steep topography, variable geology, and strong climatic gradients. These studies used new analytical tools to characterize conditions before and after a large wildfire and to analyze those data across the entire landscape of the fire. Some of the general findings may apply to other forest regions, but the details may be unique to southwestern Oregon and northwestern California. The results improve our understanding of how post-fire management …

After A Southern Pine Beetle Epidemic, Jake Delwiche

Joint Fire Science Program Briefs (2007-2012)

Southern pine beetles are a serious insect threat to pine forests in the South, from eastern Texas to Virginia. Beetles attack most pine species by boring through the bark of the tree and constructing long, winding tunnels between the bark and the wood, eventually girdling and killing the tree. They also introduce a fungus called “bluestain,” which further damages conductive systems of the tree. After an outbreak, the area of dead standing timber is usually no longer of commercial value. Forest managers are interested in reducing these fuel hot spots, both to allow forest regeneration and to reduce wildfire risk. …
