A Lake Sediment–Based Paleoecological Reconstruction of Late Holocene Fire History and Vegetation Change in Great Basin National Park, Nevada, USA
Quaternary Research (2021), 1–15 doi:10.1017/qua.2021.17 Research Article A lake sediment–based paleoecological reconstruction of late Holocene fire history and vegetation change in Great Basin National Park, Nevada, USA Christopher S. Coopera, David F. Porinchua* , Scott A. Reinemannb, Bryan G. Markc and James Q. DeGrandc aDepartment of Geography, University of Georgia, Athens, Georgia 30602, USA; bDepartment of Sociology, Geography and Social Work, Sinclair Community College, Dayton, Ohio 45402, USA and cDepartment of Geography, Ohio State University, Columbus, Ohio 43210, USA Abstract Analyses of macroscopic charcoal, sediment geochemistry (%C, %N, C/N, δ13C, δ15N), and fossil pollen were conducted on a sediment core recovered from Stella Lake, Nevada, establishing a 2000 year record of fire history and vegetation change for the Great Basin. Charcoal accu- mulation rates (CHAR) indicate that fire activity, which was minimal from the beginning of the first millennium to AD 750, increased slightly at the onset of the Medieval Climate Anomaly (MCA). Observed changes in catchment vegetation were driven by hydroclimate variability during the early MCA. Two notable increases in CHAR, which occurred during the Little Ice Age (LIA), were identified as major fire events within the catchment. Increased C/N, enriched δ15N, and depleted δ13C values correspond with these events, providing additional evidence for the occurrence of catchment-scale fire events during the late fifteenth and late sixteenth centuries. Shifts in the veg- etation community composition and structure accompanied these fires, with Pinus and Picea decreasing in relative abundance and Poaceae increasing in relative abundance following the fire events. During the LIA, the vegetation change and lacustrine geochemical response was most directly influenced by the occurrence of catchment-scale fires, not regional hydroclimate. -

Holocene Climate and Environmental Change in the Great Basin of the Western United
Holocene Climate and Environmental Change in the Great Basin of the Western United States: A Paleolimnological Approach DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Scott Alan Reinemann, M.S. Graduate Program in Atmospheric Science The Ohio State University 2013 Dissertation Committee: Dr. Bryan G. Mark, Co-Advisor Dr. David F. Porinchu, Co-Advisor Dr. Ellen Mosley-Thompson Dr. Alvaro Montenegro Copyrighted by Scott Alan Reinemann 2013 Abstract In this dissertation, I have completed a research project that focused on reconstructing past climate and environmental conditions in the Great Basin of the western United States. This research project incorporates four discrete but interrelated studies. (1) The geochemistry of lake sediments was used to identify anthropogenic factors influencing aquatic ecosystems of sub-alpine lakes in the western United States during the past century. Sediment cores were recovered from six high elevation lakes in the central Great Basin of the United States. Mercury (Hg) flux varied among lakes but all exhibited increasing fluxes during the mid-20th century and declining fluxes during the late 20th century. Peak Spheroidal Carbonaceous Particles (SCP) flux for all lakes occurred at approximately 1970, after which SCP flux was greatly reduced. Atmospheric deposition is the primary source of Hg and anthropogenically produced SCPs to these pristine high elevation lakes during the late 20th century. (2) Chironomids are used to develop centennial length temperature reconstructions for six sub-alpine and alpine lakes in the central Great Basin of the United States. Chironomid-inferred temperature estimates indicate that four of the six lakes were characterized by above average air temperatures during the post-AD 1980 interval and below average temperatures during the early 20th century. -

Sacramento Pass separates the range into two main parts, the northern and the southern Snake Range (fig. 1). The Windy Peak quadrangle is one of six quadrangles comprising the southern Snake Range and includes part of the northern boundary of the Great Basin National Park (fig. 1). The Great Basin National Park was established to help preserve the unique geology, human history, and plant and animal communities that are representative of this part of the Great Basin region. -
