The Retention, Revival, And Subjugation Of Indigenous Fire Knowledge Through Agency Fire Fighting In Eastern Australia And California, Christine Eriksen, Don Hankins

Christine Eriksen

This article explores the potential impact of training and employment with wildfire management agencies on the retention of Indigenous fire knowledge. It focuses on the comparative knowledge and experiences of Indigenous Elders, cultural practitioners, and land stewards in connection with “modern” political constructs of fire in New South Wales and Queensland, Australia, and California in the United States of America. This article emphasises the close link between cross-cultural acceptance, integration of Indigenous and agency fire cultures, and the ways in which knowledge types are shared or withheld. While agency fire fighting provides an opportunity for Indigenous people to connect and …

Beach And Surf Tourism And Recreation In Australia: Vulnerability And Adaptation, Michael Raybould

Michael Raybould

The Beach and surf tourism and recreation in Australia: Vulnerability and adaptation project has produced estimates of economic values for recreation and tourism related to beach and surf amenities across four case-study locations in Australia. Estimates of the non-market consumer surplus values of beach recreation indicate that beach recreation is worth around: $70 million per annum (p.a.) to residents of the Sunshine Coast (Qld), $32 million p.a. to residents of Clarence Valley (NSW), $6 million p.a. to residents of the Surf Coast (Vic) and $4 million p.a. for residents of Augusta-Margaret River (WA). In addition to the non-market values, real …

Defining Adequate Means Of Residents To Prepare Property For Protection From Wildfire, Trent Penman, Christine Eriksen, R Blanchi, M Chladil, A Gill, K Haynes, Justin Leonard, Jim Mclennan, Ross Bradstock

Christine Eriksen

Wildfire can result in significant loss of property and lives. Evidence shows that residents can decrease the risk of loss when they stay to defend their property. In order to safely defend a property, residents need to be adequately prepared for the wildfire conditions they face. Residents who wish to evacuate prior to the arrival of a wildfire also need to prepare their property and themselves for such an action. Despite the importance of preparation, there are no clear and quantifiable definitions of what it means to be prepared for different exposures to wildfire. Here we develop a model and …

Historic Preservation In Nazi Germany : Place, Memory, And Nationalism, Joshua Hagen

Joshua Hagen

While numerous studies have examined the post-war contestation surrounding commemorative sites associated with the legacy of Nazi Germany, relatively little attention has been dedicated to the ways in which the Nazi regime itself sought to create places of memory congruent with the movement's political and cultural goals. Indeed, party leaders sponsored a variety of disparate, and at times contradictory, programs to re-orientate some of Germany's most prominent historic places to better serve the needs of the regime. To expand our understanding of this process, this article examines the practice and rhetoric of historic preservation in Bavaria during the Nazi period …

Carbon Storage And Cycling Of Reclaimed Mine Soils In Southeastern Kentucky, Alice Jones, Kelly Barber, Peter Acton, James Fox

Alice Jones

Since the passage of the Surface Mining and Reclamation Act (SMCRA) in 1977, the most common type of surface mine reclamation is heavy compaction followed by grass seeding. To promote better vegetative recovery after mining, the Appalachian Regional Reforestation Initiative (ARRI) promotes leaving the top four feet of fill material loose and planting a seedling mix of native hardwood trees. This study aims to quantify the effects of the resulting soil bulk densities on decomposition processes through the analysis of carbon storage and cycling in the soil column. Soil carbon storage mechanisms are divided into specific size classes/pools, each corresponding …

Estimates Of Streambank Erosion In A Surface Mined Disturbed Watershed Of Southern Appalachia, Alice Jones, Kelly Foley, Darren Martin, James Fox, Peter Acton, Nathanial Adams

Alice Jones

Mountaintop coal mining is a debated environmental issue which has a significant influence on Appalachian watersheds, particularly their channel evolution. A major issue related to the mining is the increase in sediment load and transport from increased runoff and streambank erosion during storm events. Estimates of streambank erosion associated with surface mining are important presently because environmental regulations of mining are being reevaluated. This study uses a compartmental streambank erosion model to estimate rates of streambank erosion in an actively mined first-order watershed in Eastern Kentucky. The study site is Island Branch (2.2 km²), a subwatershed of the Line Fork …

Carbon Sequestration In Soils On Reforested Coal Mining Sites In Southeastern Kentucky, Alice Jones, Frances Sayler, James Fox

Alice Jones

Soil organic carbon was measured at four locations in Eastern Kentucky in order to assess the impact of surface mine reclamation through reforestation on the soil organic carbon pool. Three surface mines reforested under similar procedures 2, 5, and 14 years ago were sampled, along with soil from an undisturbed forest in the area. Soil was sampled from 4 depths, (0-5, 5-10, 10-25 and 25-50 cm) and samples were analyzed by an isotope ratio mass spectrometer for percent carbon and carbon isotopic signature. The Monte Carlo unmixing equation was used to differentiate geogenic carbon from organic carbon at the mine …

Coherent Structures And Aeolian Saltation, Jean Ellis

Jean Taylor Ellis

Aeolian sand transport models, widely employed by coastal scientists and managers, assume temporal and spatial homogeneity within the saltation field. This research questions that assumption by demonstrating that the saltation field is event-driven, therefore indicating that the saltation field is not temporally steady. The findings from this research may explain a portion of the conclusions from previous studies that indicated inequalities between model-estimated and field-measured aeolian sand transport. The relationship between unsteadiness in a turbulent wind field and pulses in a sand transport field was investigated on a beach near Shoalhaven Heads, New South Wales, Australia. Microphone-based saltation sensors, “miniphones,” …

Quantifying Nitrogen Cycling On Surface Mined Lands Using Natural Delta 15n Abundances And Fungal Relationships: An Exploratory Study, Alice Jones, Stephanie Jarvis, James Fox, Harold Rowe

Alice Jones

The use of isotopes to measure the role of mycorrhizal fungi in cycling nitrogen between soil and plants is applied to a reclaimed surface mine to illustrate the impact of surface mining on soil nutrient cycling in a terrestrial ecosystem. Isotopic relationships between soil, plants, and fungi were examined for a ~10 year old pitch pine reclaimed valley fill in Breathitt County, KY and for an undisturbed mixed mesophytic forest in Letcher County, KY. A quantitative inventory of sporocarps present, their size and substrate was performed at each site. Isotopic signatures of fungal and presumed substrate samples, dominant foliage samples …

Metals Analysis As A Tool For Understanding Headwater Health And Stream Processes In The Southern Appalachian Coal Region: An Exploratory Analysis, Alice Jones, Lee Powell, James Fox

Alice Jones

Major and trace metal analysis was applied to four coal-country headwater streams to better understand the fate of metals in headwater streams affected by mining over time and to determine headwater health. The study watersheds were located in southeastern Kentucky and consisted of an active mine site, a site mined prior to the passage of the Surface Mine Control and Reclamation Act of 1977 (SMCRA), a post-SMCRA reclaimed mine site, and an undisturbed forest control site. Dissolved water metals and suspended sediment metals were sampled at each source, middle, and outlet. Samples were analyzed on an ICP-OES, and spatial trends …

Budgeting Soil Carbon In The Clean Coal Discussion: Elemental And Isotopic Measurements And Modeling Of Soil Carbon Uptake On Reclaimed Mining Sites, Alice Jones, Peter Acton, James Fox, Harry Rowe, Darren Martin, Elliott Campbell

Alice Jones

While recent research has focused on the use of carbon capture and sequestration technology feasibility, less focus has been placed upon terrestrial carbon storage affected by coal mining in the context of the clean coal debate. Recent research has shown that the initial disturbance of soil and above-ground carbon pools caused by surface coal mining methods can produce a significant carbon loss from the terrestrial ecosystem, thus increasing the coal carbon footprint of coal. However there is a lack of information regarding the uptake of CO (sub 2) on reclaimed mining sites during re-growth and re-establishment of the soil carbon …

The Microbial Pool And Soil Carbon Cycling On Reclaimed Surface Mine Sites, Alice Jones, Guy Evans, James Fox

Alice Jones

The southern Appalachian region is an important source of coal resources. The wide scale practice of surface mining in this region leads to the landscape-scale removal of surface material and soils, a large carbon reservoir and important component of the carbon cycle. To date, few scientific studies have examined the development of the soil carbon cycle on post-reclamation mine sites in this region. In particular, development of the microbial pool and its role in carbon cycling in post-reclamation mine soils remains poorly understood. This study measured microbial biomass and soil respiration, as well as bulk soil total organic carbon, total …

The Muddy Creek Project: Evolution Of A Field-Based Research And Learning Collaborative, Alice Jones, Danita Sage, Tom Edwards

Alice Jones

For three years an on-going multidisciplinary research, teaching, and outreach collaboration has focused on the Muddy Creek Watershed in east-central Kentucky. At the core of the effort is a three-way partnership among a geologist, a geographer, and a biologist-two academic, one a state agency representative. The collaboration frequently includes additional academic partners, nonprofit and community members, and government agency personnel. It has produced graduate and undergraduate student learning experiences from individual student field projects, a course redesigned to include a major class project, and the incorporation of additional field-based components into existing coursework. Logistical and financial challenges require creativity to …

Radiocarbon Chronology And Δ13c Analysis Of Mid-To Late-Holocene Aeolian Environments, Guadalupe Mountains National Park, Texas, Usa, David Wilkins, Donald Currey

David E. Wilkins

The Red Dunes of Guadalupe Mountains National Park are quartzose sand sheets and dunes stabilized by sparse plant cover. Stratigraphy, radiocarbon dating, and δ13C analysis were examined in two of the larger arroyos for correlating evidence of aeolian deposition, which in this basin is taken as an indication of arid conditions. Four quartz-sand lithostratigraphic units, representing intervals of aeolian activity, are identified. Radiocarbon dates provide constraint on the timing of the three youngest quartz-sand units. A mid-Holocene aeolian interval, represented by a single radiocarbon date of 6350± 70 BP, is interpreted as transitional to an altithermal regime. A neopluvial period, …

Timing And Extent Of Late Quaternary Paleolakes In The Trans-Pecos Closed Basin, West Texas And South-Central New Mexico, David Wilkins, Donald Currey

David E. Wilkins

The Trans-Pecos Closed Basin is a hydrographically closed region covering 20,000 km centered on Salt Basin, 160 km east of El Paso, Texas. Geomorphic and limnetic evidence have been used to identify four major highstands for Lake King during the last glacial maximum (LGM). Additional geomorphic features from a second, recently identified, paleolake, Lake Sacramento, have been found in the Beargrass subbasin, a nested subbasin approximately 75 km northwest of Salt Basin. Radiocarbon ages of the organic material in Lake King sediments date four abrupt climate changes and rapid lacustrine transgressions during the LGM with a quasi-periodicity of 2000 yr. …
