Shortleaf Pine Sprout Production Capability In Response To Disturbances, David Charles Clabo
Shortleaf Pine Sprout Production Capability In Response To Disturbances, David Charles Clabo
Masters Theses
Shortleaf pine (Pinus echinata Mill.) seedlings are capable of sprouting and continuing growth after the stem is killed. The sprouting ability of shortleaf pine could be used to favor the species silviculturally after disturbance. Information is limited on shortleaf pine seedling sprouting after burning and clipping at different periods of the growing season and the effects of these treatments during their first three years after outplanting. Survival, seedling growth, and sprout production of shortleaf pine were evaluated after burning and clipping. The research was conducted on one, two, and three-year-old seedlings on an above average productivity site on the …
Data Quality Assessment Of Continuous Forest Inventory On State Forest Lands In Tennessee, Matthew Wade Holt
Data Quality Assessment Of Continuous Forest Inventory On State Forest Lands In Tennessee, Matthew Wade Holt
Masters Theses
The Tennessee Division of Forestry (TDF) implemented a Continuous Forest Inventory (CFI) system in 2009 for the 15 state forests, encompassing multiple physiographic land types and forest types. The initial design contained plans to measure the plots on five-year intervals. The objectives of the CFI system include: determining the growth by species and forest types for all state forest land, estimating growth models for individual trees in mixed hardwood stands, developing a harvest schedule, and assessing the impact of different silvicultural treatments over time. Following the implementation, the University of Tennessee Department of Forestry, Wildlife and Fisheries was asked to …
Value-Added Lignin Based Carbon Fiber From Organosolv Fractionation Of Poplar And Switchgrass, Andreas Attwenger
Value-Added Lignin Based Carbon Fiber From Organosolv Fractionation Of Poplar And Switchgrass, Andreas Attwenger
Masters Theses
Carbon fibers have unique properties that include high strength, low density and excellent chemical and thermal resistance. However, they have a low level of utilization because of their high price; typically around $30/kg for an entry level polyacrylonitrile (PAN) based carbon fiber. Low-cost carbon fibers derived from lignin are currently being investigated at the University of Tennessee, because using lignin as a precursor could significantly reduce production costs. Lignins obtained from the pulp and paper and the emerging biofuel industries have the potential to be used for carbon fiber production, however, they are typically unsuitable because of the high levels …
A Comprehensive Street Tree And Soil Study Along Roadways In Oak Ridge, Tennessee, Thomas Murphy Turnbull
A Comprehensive Street Tree And Soil Study Along Roadways In Oak Ridge, Tennessee, Thomas Murphy Turnbull
Masters Theses
In the early 1940s, during the early stages of the Manhatttan Project (WWII), rural communities in Anderson County, Tennessee were rapidly converted into laboratory facilities and the city of Oak Ridge. The environment that became Oak Ridge not only experienced pollutants from the laboratory activities, but also alterations from the land-use change from rural to urban. Therefore, a study was conducted to determine the impacts of land-use change from rural to urban on (1) street tree diversity and performance; and (2) the biological, chemical and physical properties, and nutrient dynamics of street tree ecosystem soils. There were a total of …
Comparison Of Oak And Sugar Maple Distribution And Regeneration In Central Illinois Upland Oak Forests, Peter J. Frey
Comparison Of Oak And Sugar Maple Distribution And Regeneration In Central Illinois Upland Oak Forests, Peter J. Frey
Masters Theses
Although white oak (Quercus alba) dominated much of the mid-west and eastern US hardwood forests prior to European settlement, changes in disturbance frequencies and habitat fragmentation, coupled with other biotic pressures, are allowing sugar maple (Acer saccharum Marshall) to displace oak in the upland forest understory. Since our understanding of how disturbance mechanisms influence oak regeneration is not fully clear, there is lack of consensus on how to employ management practices. We collected seedling microhabitat data from 5 upland oak forest sites in central Illinois, each differing in age class and/or silvicultural treatment to determine: 1) Whether …
