Aquifers Of Nebraska Ii: The Niobrara Aquifer, Dana Divine, Robert Matthew Joeckel, Sue Olafsen Lackey Dec 2017

Aquifers Of Nebraska Ii: The Niobrara Aquifer, Dana Divine, Robert Matthew Joeckel, Sue Olafsen Lackey

Conservation and Survey Division

The marine shale, chalk, marl, and chalky limestone of the Niobrara Formation directly underlie Quaternary sediments in 23 counties from south-central to northeastern Nebraska. Nevertheless, the formation serves as an aquifer only in and around Cedar, Madison, and Nuckolls counties. Niobrara aquifer wells mostly supply irrigation, domestic, and livestock needs. Two hundred of the approximately 230 active registered wells in Nebraska that are screened entirely in the Niobrara aquifer are in Cedar County and environs. About another 200 wells in this area are screened in both the Niobrara aquifer and overlying Quaternary sediments. Wells screened entirely in the Niobrara aquifer …

Mapping The Ecology Of Information: Hierarchical Habitat Selection By Nebraska Pheasant Hunters, Lyndsie Wszola Aug 2017

Mapping The Ecology Of Information: Hierarchical Habitat Selection By Nebraska Pheasant Hunters, Lyndsie Wszola

School of Natural Resources: Dissertations, Theses, and Student Research

Hunting regulations are assumed to moderate the effects of hunting consistently across a game population. A growing body of evidence suggests that hunter effort varies temporally and spatially, and that variation in effort at multiple spatial scales can affect game populations in unexpected ways. We set out to determine the causes of variation in hunting effort among ring-necked pheasant (Phasianus colchicus) hunters at four spatial scales: among regions within the state of Nebraska, among sites within a given region, among access points at a given site, and among habitat patches within a site. At each scale, pheasant hunters used direct …


Geological Principles Illustrated In The Art Along The Antelope Valley Hiker/Biker Trail – The Big X (Salt Creek Roadway/Antelope Valley Parkway) South To Q Street, Robert Diffendal, Jr. Aug 2017

Geological Principles Illustrated In The Art Along The Antelope Valley Hiker/Biker Trail – The Big X (Salt Creek Roadway/Antelope Valley Parkway) South To Q Street, Robert Diffendal, Jr.

School of Natural Resources: Faculty Publications

When the weather is good (and even sometimes when it isn’t) I occasionally walk around the periphery of the UNL city campus, often over the lunch hour, now that the trails and the sidewalks allow one to walk a complete circuit. The walk along Antelope Creek from the Big X to Q Street is beautiful. The designers of the project made nice art works on the floor of the creek and on the retaining walls on the valley sides that add to the beauty of nature.

I am a geologist and wondered about some of the art and its meaning …

The Groundwater Atlas Of Richardson County, Nebraska, Dana P. Divine, Leslie M. Howard May 2017

The Groundwater Atlas Of Richardson County, Nebraska, Dana P. Divine, Leslie M. Howard

Conservation and Survey Division

The purpose of this groundwater atlas is to synthesize a wealth of hydrogeologic data for Richardson County that has not been published in readily accessible formats previously. Many of the maps presented herein are based on data from registered well logs and test hole logs that are publicly available on-line, which become more valuable when compiled, analyzed, and discussed as a whole. The focus of the maps presented in this report is the accessibility of groundwater for pumping.


Results Of Test-Hole Drilling For Observation Well Planning In The Upper Loup Natural Resources District, Fall 2016, Douglas Hallum, Sue Olafsen Lackey Mar 2017

Results Of Test-Hole Drilling For Observation Well Planning In The Upper Loup Natural Resources District, Fall 2016, Douglas Hallum, Sue Olafsen Lackey

Conservation and Survey Division

The High Plains Aquifer underlies much of Nebraska (Figure 1). It is the primary source of groundwater within the Upper Loup Natural Resources District (ULNRD) of central Nebraska (Figure 2). Water derived from the aquifer is an important natural resource for the area and supplies water for recreation, wildlife and agriculture, as well as domestic, municipal, and industrial uses. A general lack of water level observations in the region (Figure 3), recently developed groundwater irrigated acres along the upper Calamus River (Figure 4), falling spring water levels measured in existing irrigation wells (Figure 5), and a stable to falling stream …


Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht Mar 2017

Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht

United States National Park Service: Publications

Abstract

Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.

Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …

Nest Site Selection And Nest Survival Of Greater Prairie-Chickens Near A Wind Energy Facility, Jocelyn Olney Harrison, Mary B. Brown, Larkin A. Powell, Walter H. Schacht, Jennifer A. Smith Jan 2017

Nest Site Selection And Nest Survival Of Greater Prairie-Chickens Near A Wind Energy Facility, Jocelyn Olney Harrison, Mary B. Brown, Larkin A. Powell, Walter H. Schacht, Jennifer A. Smith

School of Natural Resources: Faculty Publications

Rapid development of wind energy facilities in the Great Plains of North America has raised concerns regarding their potential negative impact on the nesting ecology of Greater Prairie-Chickens (Tympanuchus cupido pinnatus). We investigated the effects of a pre-existing, 36-turbine wind energy facility on nest site selection and nest survival of Greater Prairie-Chickens in the unfragmented grasslands of the Nebraska Sandhills, USA. In 2013 and 2014, we monitored 91 nests along a 24-km disturbance gradient leading away from the wind energy facility. We found little evidence of an effect of the wind energy facility on Greater Prairie-Chicken nest site …

Conservation and Survey Division

The term “groundwater” has come to be all but synonymous with Nebraska. Nearly three-quarters of the volume of the High Plains aquifer lies beneath the State, and groundwater maintains our streams, our ecosystems, our people, and our vitally important agricultural economy. Although Nebraska’s total groundwater resource is vast, it is also quite vulnerable to changes induced by natural processes and by humankind, necessitating a long-term commitment to wise management through informed decision making. Monitoring, studying, and reporting are the essential basis for such management and, ultimately, for meeting the myriad challenges presented by change.

The personnel of the Conservation and …
