Windbreak Management, Craig Stange

School of Natural Resources: Faculty Publications

The windbreaks on your farm are an important part of the agricultural landscape. They provide protection for the farmstead, livestock, and crops; provide habitat for wildlife; and contribute to an overall healthy environment for you and your family. They are living systems with youth, maturity, and old age. Like any other living thing they need proper care and management in order to continue to function at their best.

Windbreak management requires an understanding of how your windbreak works. Your goal is to maintain the health and vigor of individual trees and shrubs while maintaining the overall structure of the windbreak …

Inventory For Endangered, Threatened, And Rare Plant And Animal Species Within The Floodplain Corridor Of The Middle Loup River Basin, Nebraska Natural Heritage Program

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

In April 1996 the Nebraska Game and Parks Commission (NGPC) entered into agreement with the U. S. Department of the Interior Bureau of Reclamation (BOR) to conduct inventory work for endangered, threatened, and rare plant and animal species within the floodplain corridor of the Middle Loup River basin in Nebraska. This district includes the Farwell and Sargent Irrigation Districts. The impetus for such inventory work is the renewal of current water services contracts between BOR and irrigation districts that will expire in 1988. BOR has stated the need to balance the interests of the irrigation districts and their clients, with …

1996 Ecological Evaluation Cunningham Creek Potential Research Natural Area, A Final Report, Terri Hildebrand

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Cunningham Creek potential Research Natural Area (RNA) is located approximately 27.2 km (17 miles) east-southeasterly of Crawford, Nebraska or 40 km (25 miles) southwesterly of Chadron, Nebraska. Located on the Pine Ridge District of the Nebraska National Forest, the site is included in the Pine Ridge ecosystem of western Nebraska. Four hundred hectares (1000 acres) consisting of deciduous woodlands, pine forests, and upland prairies are located in the survey area. Inclusions of wet meadows, oak woodland, and aquatic systems intermingle in the deciduous woodland. Cattle grazing and recreation are the primary uses of the area. The purpose of this …

Scale Issues In Soil Moisture Modelling: Problems And Prospects, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Soil moisture storage is an important component of the hydrological cycle and plays a key role in land-surface-atmosphere interaction. The soil-moisture storage equation in this study considers precipitation as an input and soil moisture as a residual term for runoff and evapotranspiration. A number of models have been developed to estimate soil moisture storage and the components of the soil-moisture storage equation. A detailed discussion of the implication of the scale of application of these models reports that it is not possible to extrapolate processes and their estimates from the small to the large scale. It is also noted that …

Nectarivorous Feeding Mechanisms In Bats, Patricia W. Freeman

School of Natural Resources: Faculty Publications

Cranio-dental characteristics are quantified between micro- and megachiropteran nectarivores and compared with microchiropteran animalivores, frugivores, and megachiropteran frugivores. Microchiropteran nectarivores share many characteristics with megachiropteran nectarivores and frugivores, but differ in having a long, narrow head. Megachiropterans have wide zygomata, which would allow for more jaw musculature. Diminutive cheekteeth are characteristic of nectarivory in both suborders, but both have relatively large canines. Teeth in nectarivores can occupy as little as a tenth of the palatal area compared to nearly two-thirds in microchiropteran animalivores. The proportion that the dilambdodont stylar shelf occupies of molars in microchiropteran nectarivores can be as much …

Identification And Conservation Strategy For Sandhills Fens In Cherry County Nebraska, Gerry Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

In the Sandhills, fens are generally found in two locations: in stream valleys often near the headwaters and at the upper end of Sandhills lakes and marshes. In both areas groundwater discharge into the valleys can be abundant, and in some cases, has led to the development of fens on the valley floor. A few Sandhills fens approach 500 ac (200 ha) in size and are among the largest fens in the Great Plains. Most Sandhills fens are smaller, some only a few acres (ha) or less in size.

Water Runoff Monitoring In Arid Areas Using Integrated Remote Sensing And Gis Techniques, G. G. Lemoine, Anatoly A. Gitelson, E. Adar, J. G.M. Bakker

School of Natural Resources: Faculty Publications

Our paper discusses the proposed methodology for the implementation of a monitoring tool for surface water run-off in (semi-)arid areas. This tool is being developed as part of a two year multi-disciplinary shared cost project supported by the European Union AVICENNE initiative. The tool aims at supporting decision making and planning in water run-off management for sustainable development of water resources for human settlement and regeneration of desertification-prone areas in the arid climate zone.

The initial phase of the project (1995) consists of the testing of various remote sensing products for DTM generation and surface characterization. Both SPOT stereo pairs …

Reflectance In The Red And Near Infra-Red Ranges Of The Spectrum As Tool For Remote Chlorophyll Estimation In Inland Waters: Lake Kinneret Case Study, Anatoly A. Gitelson, Yosef Z. Yacobi

School of Natural Resources: Faculty Publications

Signature analysis of reflectance spectra was used for the selection of the most suitable spectral bands for remote sensing of chlorophyll in inland waters. The parameters of the reflectance peak near 700 nm were employed for construction of algorithms for chlorophyll determination. The best model, validated by independent data sets, enabled estimation of chlorophyll concentration with an error < 0.6 mg/m³ for period of low Chl concentration and < 6.5 mg/m³ for period of the phytoplankton bloom. For the purpose of chlorophyll mapping in Lake Kinneret, the use of three relatively narrow spectral bands was sufficient. Radiometric data were also used to simulate radiances …

Remote Sensing Of Chlorophyll In Lake Kinneret Using Highspectral- Resolution Radiometer And Landsat Tm: Spectral Features Of Reflectance And Algorithm Development, Yosef Z. Yacobi, Anatoly Giltelson, Meir Mayo

School of Natural Resources: Faculty Publications

High-resolution reflectance spectra in the range of 400-850 nm were obtained from Lake Kinneret during a period when dense populations of the dinoflagellate Peridinium gatunense dominated the phytoplankton. Chlorophyll (ChI) concentrations ranged from 5.1 to 185 mg m^-3 and from 2.4 to 187.5 mg m^-3 in the samples of two independent experiments. The most prominent features of the reflectance spectra were: (i) a wide minimum from 400 to 500 nm; (ii) a maximum at 550-570 nm, which did not surpass 3% in samples with high ChI concentration (>20 mg m^-3), indicating a strong absorption by …

Seasonal Land-Cover Regions Of The United States, Thomas R. Loveland, James W. Merchant, Jesslyn F. Brown, Donald O. Ohlen, Bradley C. Reed, Paul Olson, John Hutchinson

School of Natural Resources: Faculty Publications

Research on global change has been hindered by deficiencies in the availability Wand quality of land-cover data (Mather and Sdasyuk 1991; Townshend 1992). To address this deficiency, the U.S. Geological Survey (USGS) and the University of Nebraska- Lincoln have collaborated in developing a method of land-cover characterization that is suitable for research on global change and on regional patterns of land cover (Loveland et al. 1991; Brown et al. 1993). This methodology is based upon statistical analysis of multidate, meteorological satellite imagery acquired by the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Reso- lution Radiometer (AVHRR) sensor complemented …
