Polycentric Governance In Nebraska, U.S., For Ground And Surface Water, Theresa Jedd, Anthony B. Schutz, Mark Burbach
School of Natural Resources: Faculty Publications
This chapter describes the locally driven, but centrally coordinated, water governance model in Nebraska, U.S. It offers a snapshot of water resources and the importance of agriculture, then moves to the relevant political institutions in the state, and federal controls related to water quantity. The focus of the chapter is on the Nebraska Department of Natural Resources’ (NeDNR) and Natural Resources Districts’ (NRDs) management of surface and groundwater, which has some distinct and some overlapping authority. The main area of overlap is in addressing the connection between ground and surface water, particularly in situations when either or both are over …
Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape
Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape
School of Natural Resources: Faculty Publications
Conclusion
Highlighting the advantages and disadvantages of carbon offsetting options in the context of the state of Nebraska, this discussion shows that the choice and decisions about which option is better than the other depends on the interests at play and expected outcomes of the participation in carbon markets. However, irrespective of the motive to engage in emission reduction projects for carbon marketing, factors such as cost, and project efficiency can never be overlooked. Given the options discussed in this report, Nebraska has a lot of potential for carbon offsetting or emission reduction projects that would not only reduce and …

School of Natural Resources: Faculty Publications
The Aransas-Wood Buffalo population of Whooping Cranes (Grus americana) migrates approximately 4000 km through the central Great Plains biannually, between their breeding and wintering grounds. Whooping Cranes depend on stopover sites to provide secure resting locations and the caloric resources necessary to complete their migration, such as the USFWS-designated critical habitat area in the Central Platte River Valley (CPRV) of Nebraska. This area includes braided river habitat characterized by low-elevation and submerged sandbars, which provide important roosting and foraging opportunities for migrating Whooping Cranes. We used long-range photography, videography, and behavioral scan sampling to document forage items consumed by Whooping …

River Otter Distribution In Nebraska, Nathan R. Bieber, Samuel P. Wilson, Craig R. Allen
River Otter Distribution In Nebraska, Nathan R. Bieber, Samuel P. Wilson, Craig R. Allen
School of Natural Resources: Faculty Publications
The river otter (Lontra canadensis) was extirpated from Nebraska, USA, in the early 1900s and reintroduced starting in 1986. Information is needed regarding the distribution of river otters in Nebraska before decisions can be made regarding its conservation status. Understanding distribution of a species is critically important for effective management. We investigated river otter distribution in Nebraska with occupancy modeling and maximum entropy (Maxent) modeling using 190 otter sign observations on Nebraska’s navigable rivers and 380 historical otter records from November 1977 to April 2014. Both methods identified the Platte River, Elkhorn River, central and eastern Niobrara River, …

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 …

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 …
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 …

Correction Of Location Errors For Presence-Only Species Distribution Models, Trevor Hefley, David M. Baasch, Andrew J. Tyre, Erin E. Blankenship
School of Natural Resources: Faculty Publications
1. Species distribution models (SDMs) for presence-only data depend on accurate and precise measurements of geographical and environmental covariates that influence presence and abundance of the species. Some data sets, however, may contain both systematic and random errors in the recorded location of the species. Environmental covariates at the recorded location may differ from those at the true location and result in biased parameter estimates and predictions from SDMs.
2. Regression calibration is a well-developed statistical method that can be used to correct the bias in estimated coefficients and predictions from SDMs when the recorded geographical location differs from the …
