Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht
Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht
United States National Park Service: Publications
Executive Summary
Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.
A potential bison …

A Floristic Survey Of Selected Sites In The Loup River Valley, Nance County, Nebraska, Diane M. Flynn, Steven J. Rothenberger
A Floristic Survey Of Selected Sites In The Loup River Valley, Nance County, Nebraska, Diane M. Flynn, Steven J. Rothenberger
The Prairie Naturalist
The Loup River Valley of Nebraska contains natural, undisturbed wet meadows with significant plant diversity. Even though these sites are infrequent and are often intermixed with heavily grazed pastures or cultivated fields, they support numerous plant and animal species that do not occur elsewhere. We surveyed three study sites (an ungrazed wet meadow; a grazed wet meadow; and a riparian area) that totaled approximately 68.8 ha during the 2010 and 2011 growing seasons. We compiled an annotated vascular plants checklist for the study area that included 244 plant species of which about 49% (119) were new county records. The mean …
A Geospatial Approach For Prioritizing Wind Farm Development In Northeast Nebraska, Usa, Adam Miller, Ruopu Li
A Geospatial Approach For Prioritizing Wind Farm Development In Northeast Nebraska, Usa, Adam Miller, Ruopu Li
School of Natural Resources: Faculty Publications
Being cleaner and climate friendly, wind energy has been increasingly utilized to meet the ever-growing global energy demands. In the State of Nebraska, USA, a wide gap exists between wind resource and actual energy production, and it is imperative to expand the wind energy development. Because of the formidable costs associated with wind energy development, the locations for new wind turbines need to be carefully selected to provide the greatest benefit for a given investment. Geographic Information Systems (GIS) have been widely used to identify the suitable wind farm locations. In this study, a GIS-based multi-criteria approach was developed to …
Architecture, Heterogeneity, And Origin Of Late Miocene Fluvial Deposits Hosting The Most Important Aquifer In The Great Plains, Usa, R. Matthew Joeckel, Steve R. Wooden Jr., Jesse T. Korus, Jon Garbisch

Department of Earth and Atmospheric Sciences: Faculty Publications
The Ash Hollow Formation (AHF) of the Ogallala Group is an important sedimentary archive of the emergence of the Great Plains and it contains major groundwater resources. Stratal patterns of constituent alluvial lithofacies demonstrate that the AHF is much more heterogeneous than is commonly assumed. Very fine- to fine-grained sandstone dominate overall, chiefly lithofacies Sm (massive to locally stratified sandstone). Stacked, thin sheets of Sm with accretionary macroform surfaces are common, indicating that many sandstone architectural elements originated as compound-bar deposits in dominantly sand-bed streams. Channel forms are difficult to identify and steep cutbanks are absent. Multiple units of lithofacies …

Introduction
During the last century, much of the prairie within the Northern Great Plains has been plowed for cropland, planted with non-natives to maximize livestock production, or otherwise developed, making it one of the most threatened ecosystems in the United States. Within Nebraska, greater than 77% of the area of native mixed-grass prairie has been lost since European settlement (Samson and Knopf 1994). The National Park Service (NPS) plays an important role in preserving and restoring some of the last pieces of intact prairies within its boundaries. The stewardship goal of the NPS is to “preserve ecological integrity and cultural …
