Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek
Mapping Potential Crp Land And Determining Crp Profitability In Lancaster County, Jamie Pesek
Department of Environmental Studies: Undergraduate Student Theses
Annually 17 tons of soil is lost due to the erosion of agriculture land. A majority of the soil lost is fertile topsoil, which can render the land unproductive. The Conservation Reserve Program (CRP) was enacted to reduce the high erosion rates on agriculture land by giving landowners a monetary incentive to let their land lay idle and allow the soil to regenerate. Although there is awareness of the benefits of CRP, little effort has been put toward delineating CRP eligible land. In this project, Geographical Information Systems were used to map CRP eligible land in Lancaster County, Nebraska based …
Extent Of Coterminous Us Rangelands: Quantifying Implications Of Differing Agency Perspectives, Matthew Clark Reeves, John E. Mitchell
Extent Of Coterminous Us Rangelands: Quantifying Implications Of Differing Agency Perspectives, Matthew Clark Reeves, John E. Mitchell
USDA Forest Service / UNL Faculty Publications
Rangeland extent is an important factor for evaluating critical indicators of rangeland sustainability. Rangeland areal extent was determined for the coterminous United States in a geospatial framework by evaluating spatially explicit data from the Landscape Fire and Resource Management Planning Tools (LANDFIRE) project describing historic and current vegetative composition, average height, and average cover through the viewpoints of the Natural Resources Inventory (NRI) administered by the Natural Resources Conservation Service and the Forest Inventory and Analysis (FIA) program administered by the US Forest Service. Three types of rangelands were differentiated using the NRI definition encompassing rangelands, afforested rangelands, and transitory …

Cottonwood Riparian Site Selection On The Cheyenne River Sioux Reservation, Julie A. Thorstenson, Diane Rickerl, Janet H. Gritzner
Cottonwood Riparian Site Selection On The Cheyenne River Sioux Reservation, Julie A. Thorstenson, Diane Rickerl, Janet H. Gritzner
Great Plains Research: A Journal of Natural and Social Sciences
The construction of the Oahe Dam on the Missouri River eliminated thousands of acres ofriparian and floodplain lands on the Cheyenne River Sioux Reservation in South Dakota. Restoration is needed to replace wildlife habitat. This study focused on site selection for native cottonwood (Populus deltoides Bartr. Ex Marsh. ssp. Monilifers (Ait.) Eckenwalde) restoration to help mitigate this loss. Geographic information systems technologies were used to develop a suitability model for cottonwood restoration. Tribal lands were extracted from a digital dataset oflandownership. Those touched by or included in a 46 m border of the Moreau River were candidate sites. Of …

Comparisons Between Educational Map Software Displaying Soil Data, Laura A. Kocur
Department of Computer Graphics Technology Degree Theses
The use of technology in the classroom is becoming more widespread, and the area of agronomy is no different. Utilization of various mapping technology is more common in instructional components in the classroom, although the impacts of software usability have not yet been explored. Maps available over the Internet are identified as an area in which usability is not known, nor are there any fixed standards or conventions to govern the display of them. The recently developed mapping prototype is intended to increase accessibility to map data used in class, as well as make it easier to use the data. …

In order to maintain a proper balance between development pressure and water resources protection, and also to improve public participation, efficient tools and techniques for soil and water conservation projects are needed. This paper describes the development and application of a web-based watershed management spatial decision support system, WebWMPI. The WebWMPI uses the Watershed Management Priority Indices (WMPI) approach which is a prioritizing method for watershed management planning and it integrates land use/cover, hydrological data, soils, slope, roads, and other spatial data. The land is divided into three categories: Conservation Priority Index (CPI) land, Restoration Priority Index (RPI) land, and …

Aspen Bibliography
Quaking aspen (Populus tremuloides Michx.) are the most widely distributed tree species across North America, but its dominance is declining in many areas of the western United States, with certain areas experiencing rapid mortality events over the past decade. The loss of aspen from western landscapes will continue to profoundly impact biological, commercial, and aesthetic resources associated with aspen. However, many options are available for its restoration. Advances in remote sensing technologies offer cost-effective means to produce spatial and quantitative information on the distribution and severity of declining aspen at many scales. This report describes the development and application of …
