During the historic mining episodes at Cagle Saltpetre Cave, wooden leaching vats needed for the lixiviation of calcium nitrate from mined sediments (from which saltpeter was then produced) were constructed and used in the cave. When mining operations ceased, these features were abandoned and preserved in situ, some remaining virtually intact. Their remarkable preservation enabled tree-ring dating of timbers associated with these vats to be accomplished. Tree rings from oak planks used in the construction of the leaching vats were measured to 0.001 mm precision on a Velmex measuring system. Using COFECHA software, we crossdated the measurement series to both the Norris Dam State Park and Piney Creek Pocket Wilderness white oak reference chronologies, spanning the years from 1633 to 1982, obtained from the International Tree-Ring Data Bank. Graphical comparisons via scatter plots were inspected to ensure correct temporal placements. The final chronology developed from 39 dated series correlated very highly with the Norris Dam State Park reference chronology (r = 0.49, n = 170 yrs, t = 7.29, p < 0.0001) and verified that our site chronology extends from 1692 to 1861. The results of our analyses indicate that saltpeter was mined and processed at the site during separate episodes throughout the 19th Century. Additionally, saltpeter-processing technology changed throughout the course of the mining operations.

We investigated the potential for using long-archived wood samples extracted from archaeological contexts at four Mississippian Period (AD 900–1600) settlements in eastern Tennessee for tree-ring dating purposes. Sixteen wood samples recovered from prehistoric sites were analyzed to: (1) crossmatch samples from each site with the intent of determining the relative chronological order of sites, (2) establish a floating prehistoric tree-ring chronology for eastern Tennessee, (3) determine the applicability of dendrochronology in prehistoric archaeology in eastern Tennessee, and (4) establish a strategy for future research in the region. We succeeded in crossmatching only three of the 16 tree-ring sequences against each other, representing two sites relatively close to each other: Upper Hampton and Watts Bar Reservoir. The average interseries correlation of these three samples was 0.74 with an average mean sensitivity of 0.26, and they were used to create a 131-year-long floating chronology. The remaining samples contained too few rings (15 to 43) for conclusive crossmatching. Our results demonstrate that dendrochronological techniques may be applied to the practice of prehistoric archaeology in the Southeastern U.S., but highlight the challenges that face dendroarchaeologists: (1) poor wood preservation at prehistoric sites, (2) too few rings in many samples, (3) the lack of a reference chronology long enough for absolute dating, and (4) the lack of a standard on-site sampling protocol to ensure the fragile wood samples remain intact.

Dendroarchaeology has a discontinuous history in the Southeastern United States, mostly because of misconceptions (the Southeast is too mesic), bad sampling practices (no standard protocol exists for preserving prehistoric wood samples), and a lack of reference tree-ring chronologies long enough to date wood from the abundant prehistoric sites. The majority of archaeological applications in recent years has focused on the dating of historic sites and structures to verify the documented year(s) of construction largely in response to requests from historical agencies to verify when a particular structure was built. We have found that most structures are one to two generations younger than their reported date(s) of construction, but most agencies find this information useful as tree-ring dating lends historical credibility to any site. The future of dendroarchaeology in the Southeast is encouraging but many more trained experts are needed to meet the demand of dating historical structures and sites. Furthermore, once a sampling protocol becomes standardized for retrieving wood from prehistoric sites, the potential for absolute dating of these sites is enormous given that abundant wood is archived in locations throughout the Southeast.

The Hoskins House is a two-story, single pen log structure located in Tannenbaum Historic Park, Greensboro, North Carolina. The house is thought to have been built by Joseph Hoskins, who lived in Guilford County from 1778 until his death in 1799. Previous archaeological testing of soil around the house yielded over 1000 artifacts, and the ceramics of these gave a Mean Ceramic Date (MCD) of 1810 as a possible initial year of construction. Our objective was to date the outermost rings on as many logs as were accessible in the Hoskins House to determine the year or range of years when the house was likely built. We compared 37 ring-width measurement series from 28 white oak group logs with a composite reference chronology created from three oak reference chronologies from Virginia. We found that the logs were cut over a 3-year period from 1811 to 1813, lending credence to the initial MCD of 1810. Joseph Hoskins had already passed away in 1799 and the property was deeded to his two sons, Joseph and Ellis. Ellis Hoskins eventually was later deeded sole possession of the property. The two-story log house located at Tannenbaum Historic Park may be more correctly called the ‘‘Ellis Hoskins House’’ rather than the ‘‘Joseph Hoskins House.’’

Muslims of Middle Eastern and Turkish origin, whether longtime immigrants, recent refugees, or students living in America temporarily, are an important part of the changing ethnic and religious landscape in the Southeast U.S. In the aftermath of 9/11, much attention has been shifted upon Islam and the Middle East. Discrimination and a lack of mutual understanding and tolerance between the selected populations and native-born, non-Muslim Americans are persistent problems. The Knoxville Turkish Cultural Center and the Istanbul Center of Atlanta recognize and reflect the contemporary need for intercultural and interfaith awareness, education, and dialogue to promote tolerance. I argue that while these organizations serve to integrate incoming populations and encourage inter-group, inter-cultural, and inter-religious interaction, they also act as a pressure valve and site of intra-group identity formation. This case study reveals the many ways in which Muslims are contributing to American culture and society while simultaneously redefining, reconfirming and even solidifying their own cultural markers, social boundaries, beliefs, and identities through their community relations and through their involvement with KTCC and IC.

Geographic Information Systems (GIS) have demonstrated their utility in predictively modeling the location of archaeological sites, and providing a framework for cataloging sites eligible for heritage management status. The intent of this GIS-based study is to begin to create a geohistorically organized database of information culled from historic documents and archaeological excavation. In this case study of postbellum land tenure in Hillsborough County, Florida, a GIS-based approach is used to demonstrate the impacts of federal and state land ownership policy decisions during the Reconstruction Era and beyond. GIS data are also used to reveal information about how people use their allotted environment to non-verbally communicate their perceptions of the world and their place in it. Finally, GIS are shown to be ideally suited for allowing multi-scalar, diachronic comparisons of archaeological sites and materials. This research was conducted according to the concepts of Actor-Network-Theory (ANT), which assumes there is a generalized symmetry between the agency of human actors and non-human actants (i.e. it does not assume the primacy of human intentional action). ANT accepts that materials can carry non-verbal messages (e.g. colors, aromas, tactility), which affect how humans interact, communicate, and organize themselves in space. ANT allows for the use of scales based on human action, and analyses that are based standardized metrologies. Finally, ANT obviates being limited to strict categories of macro- and micro-, by accepting that networks may bridge both. This research shows that two rural communities have undergone similar growth trajectories, with a historically black community having experienced some setbacks in the early 20th century. However, the results show that the rural African American community was not more subdivided than the neighboring Euro-American community, contrary to initial expectations. Additionally, there is a suggestion that communities may move socially important buildings such as churches schools to the community center or periphery, depending on the intended recipient of the message. The study also documents the centralization, concentration, and clustering of the county's African American population through time.

Forestry Best Management Practices (BMPs) include guidelines, recommendations, and protocols utilized to protect forest water quality from nonpoint source pollutants (NPSP). Sediment is the most common NPSP associated with forest operations, and BMPs are implemented primarily to reduce erosion and potential sediment delivery to streams. Skid trails, stream crossings, forest roads, decks, and harvest areas are major forest operational features that have the potential to erode and deliver sediment to streams. These five features are also common BMP categories evaluated by states across the southeastern U.S. Although BMPs are designed to minimize erosion and sediment delivery, the exact relationship between BMP implementation rates, erosion rates, and potential sediment delivery is largely unexamined. Specifically, the inherently intuitive but unverified concept that increasing levels of BMP implementation decreases erosion and sediment delivery associated with forest harvesting. This hypothesis was tested in this project at five operational features located within three physiographic regions, including the Mountains, Piedmont, and Coastal Plain, across clearcut harvest sites in the southeastern U.S. First, BMP implementation rates, audit questionnaires, and state guidelines were compared across 13 states in the southeastern region at 116 clearcut harvest sites. Overall, BMPs were implemented at an average rate of 90.1% in the southeastern United States, thus demonstrating that BMPs are currently being implemented consistently at high levels throughout the region. Across all regions, average BMP implementation rates were highest at harvest areas (95.6%), followed by decks (92.7%), haul roads (91.9%), stream crossings (88.2%), and skid trails (82.9%). Average BMP implementation rates for Mountain stream crossings (83.9%) and skid trails (76.1%) were significantly lower than rates calculated in the Piedmont and Coastal Plain, and had the lowest implementation rate for any feature in any region. These findings indicate that skid trails and stream crossings, especially in the Mountains, may benefit the most from enhanced BMP implementation and resources. In the second manuscript, the relationship between BMP implementation, estimated erosion, and potential sediment delivery were examined in three regions of Virginia and North Carolina. This study is one of the only forestry studies that have presented sediment delivery ratios by operational feature and physiographic region. BMP implementation rates and sediment delivery ratios were poorly correlated, however, a significant inverse relationship existed between BMP implementation and the total sediment mass delivered to streams (Spearman ρ = -0.2206, p-value = 0.0027). Generally, as BMP implementation increased, erosion rates and the amount of sediment delivered to streams also decreased. Additionally, this study demonstrated that most of the erosion generated by clearcutting operations in the southeast is trapped in either the harvest area or in Streamside Management Zones (SMZs) prior to reaching the stream. In the third manuscript, BMP implementation rates and erosion estimates were categorized into three BMP levels (BMP−, BMP-standard, BMP+) which represent low, moderate, and high levels of BMP implementation, respectively. Skid trails and haul roads generally had the highest erosion estimates, regardless of BMP level and physiographic region. Non-parametric correlation analyses indicated that significant inverse relationships existed between BMP implementation rates and erosion estimates at skid trails (Spearman ρ = -0.589, p-value < 0.0001), haul roads (Spearman ρ = -0.388, p-value < 0.0001), and harvest areas (Spearman ρ = -0.2305, p-value = 0.0169), while decks and stream crossings were more poorly correlated with erosion estimates. This reinforces the need for BMP audit questions that specifically address ground cover and bare soil, water control structures, gradients, and stabilization to better address potential erosion and sedimentation. Clearcut areas, erosion and sediment estimates, and sediment removal efficiencies were presented for the Mountains, Middle/Lower Coastal Plain, and Piedmont/Upper Coastal Plain for the fourth, fifth, and sixth manuscripts, respectively. Regardless of BMP level and physiographic region, a combination of harvest areas, skid trails, and haul roads were responsible for over 95% of potential sediment delivery. Increasing site-wide BMP implementation from BMP− to BMP+ could reduce sediment delivery by 70% in all physiographic regions. High levels of BMP implementation were most effective at reducing potential erosion and sediment delivery from skid trails and haul roads throughout the southeast. Findings from these studies demonstrate that current BMPs are highly effective at mitigating sediment. In the southeastern U.S., increasing levels of BMP implementation effectively reduce both potential erosion and sedimentation associated with forest harvesting. Generally, both estimated erosion and sedimentation associated with clearcutting in the region is much lower than rates associated with other land uses such as development or agriculture, especially when BMPs are implemented at standard or high levels. However, several opportunities exist to improve the effectiveness of BMPs in the southeastern U.S. Skid trails, haul roads, and stream crossings consistently had the lowest BMP implementation rates and highest estimated erosion rates and sediment delivery ratios. While these features only represent a small proportion of total clearcut area in the southeast, they are responsible for a disproportionate amount of sediment delivery and should receive more attention and resources during the pre-harvest planning and closure processes. Conclusively, this project addresses several knowledge gaps pertaining to water quality impacts resulting from harvesting operations in the southeastern U.S. For instance, this is only the third project that has presented sediment delivery ratios associated with forest operations in the southeastern U.S., and the first to do so for the Mountains and Coastal Plain regions. On average, SMZs and harvest areas trap 66-96% of sediment on-site before it can be deposited into streams. Additionally, this project provides one of the first and most comprehensive regional comparisons of state BMP manuals, audits, and programs in-field using a third-party approach. Several significant differences existed among state BMP programs and protocol, and states may need to design specific BMP guidelines and audit protocol for major physiographic regions to address the challenges and variation of on-site conditions inherent of each region. Additionally, this project presents one of the only regional-scale estimates of sediment and efficiencies of increased levels of BMP implementation at mitigating sediment associated with forest operations in the southeastern U.S. Conclusively, this project provides forest managers, state and federal agencies, and policymakers with a robust assessment on the effectiveness of forestry BMPs in the southeast. / Doctor of Philosophy / Forestry Best Management Practices (BMPs) are used throughout the southeastern U.S. to minimize the impacts that harvesting has on soil and water resources. Eroded soil that is eventually deposited into streams as sediment is the most important pollutant that BMPs address in forestry. Common BMP guidelines utilized to minimize sediment include leaving riparian buffers along streams, providing ground cover, minimizing slopes on roads, and using water control structures to divert runoff from road systems. The exact relationship between forestry BMPs, erosion, and sediment delivery is largely unexamined. Objectively, this study was designed to provide a better understanding of this relationship, and to present estimates of erosion and sediment delivery resulting from clearcut harvesting on over 100 harvest sites across 13 states with diverse conditions and topography in the southeastern U.S. Forestry BMPs are being implemented at an average rate of 90.1% across the southeast. BMPs are implemented at higher rates in the Coastal Plain, followed by the Piedmont and Mountains. Generally, harvest areas had the highest BMP implementation rates, followed by decks, haul roads, stream crossings, and skid trails, respectively. This relationship was consistent across most regions and states. Logging decks, which are areas where wood was transported for processing and loading onto logging trucks, were generally located distantly from streams and followed most state-approved BMPs. Whereas skid trails, which are low-standard temporary roads trafficked during primary transport and require water diversion structures such as waterbars, occupied a much larger area and were generally located on much steeper slopes. Mountain skid trails leading to stream crossings are concerning because of their low BMP implementation rates and high erosion potential. These features would greatly benefit from increased ground cover and water control structures. Forestry BMPs reduce both erosion and sedimentation associated with clearcutting. The highest level of BMP implementation reduces potential sediment by over 70% in all regions, and the highest BMP level is most effective at reducing sediment from skid trails and forest roads. Average sedimentation rates, especially at the highest BMP level, calculated for Mountains, Piedmont, and Coastal Plain clearcuts are considerably lower than sedimentation rates associated with agricultural and developmental land uses. Clearcut forestland, which is generally the most erodible time period during a forest's cycle, only makes up 1-2% of total forestland in the southeast annually. Both erosion and sedimentation rates should decrease further in the years following harvesting as the site revegetates and trees begin to reestablish. This study verifies that BMPs are highly effective at reducing erosion and sediment while subsequently providing estimates of erosion and sediment delivery based on ranges of BMP implementation that state forestry agencies can use to better quantify the effectiveness of their BMPs.
