Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones Jan 1983

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

For the purposes of this book, the Northern Great Plains are defined as the states of Nebraska, North Dakota, and South Dakota. As a physiographic concept, the northern part of the great interior grasslands of North America is, of course, much broader in geographic extent than the Dakotas and Nebraska, but the three states lie in the heart of the region, and thus the title for this work seems appropriate. Our expectations in writing Mammals of the Northern Great Plains were to provide a comprehensive, yet semitechnical, treatmeat of free-living mammals that would prove useful to specialist and nonspecialist alike. …

Agricultural Meteorology In China, Norman J. Rosenberg Jan 1982

Agricultural Meteorology In China, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

During nearly five weeks in China (May-June 1981), the author visited scientific institutions and experiment stations engaged in agricultural meteorology and climatology research and teaching. The facilities, studies, and research programs at each institution are described and the scientific work in these fields is evaluated. Agricultural meteorology and climatology are faced with some unique problems and opportunities in China and progress in these fields may be of critical importance to that nation in coming years. The author includes culinary notes and comments on protocol in China.


A Digital Archive Of Northern Hemisphere Snow Cover, November 1966 Through December 1980, Kenneth F. Dewey, Richard R. Heim Jr. Jan 1982

A Digital Archive Of Northern Hemisphere Snow Cover, November 1966 Through December 1980, Kenneth F. Dewey, Richard R. Heim Jr.

School of Natural Resources: Faculty Publications

The purpose of this article is to acquaint the research community with a new data base—a digitized archive of Northern Hemisphere snow cover. Historically, those researchers who needed snow cover data for climatic and atmospheric boundary layer studies have had to rely on the irregularly spaced (and in some regions, sparse) grid of point observations. Northern Hemisphere Weekly Snow and Ice Cover Charts, which are created from analyzed satellite imagery at the National Earth Satellite Service (NESS), have been available on an operational basis since late 1966. Each of these weekly charts for the period November 1966 through December 1980 …

Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers Jan 1981

Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers

School of Natural Resources: Faculty Publications

Wildlife cannot exist without food and protective cover. Natural and planted woodlands contribute significantly to these essentials. This circular describes habitat needs of wildlife, recommends forestry practices for habitat improvement, and gives examples of practices to improve habitat for pheasant, quail, and deer.

Variety, rather than uniformity of vegetation, benefits most wildlife species. Management which results in a diverse plant community with many stages of growth can increase the numbers and species of wildlife. Techniques which create improved conditions for woodland wildlife are fundamentally the same as those designed to grow good timber.

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher Nov 1980

Vegetative Community Descriptions For The North Platte River In Wyoming And Nebraska, Lynn Fisher

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

A description of the vegetative communities in an area will provide an insight to wildlife potential and use of that area. Wildlife and its corresponding habitat are recognized as important for recreation and to the overall environmental quality of an area. The Water and Power Resources Service, Lower Missouri Region, is presently engaged in a study of the Platte River Basin, including an evaluation of wildlife habitat and associated environmental needs. Quantification of wildlife habitat along the South Platte River has been completed. Vegetation communities were described and habitat maps were prepared from color infrared aerial photographs (scale – 1:24,000). …

Nebraska Trapping, George Schildman, Frank Andelt, Jim Brunner Jan 1980

Nebraska Trapping, George Schildman, Frank Andelt, Jim Brunner

Nebraska Game and Parks Commission: Publications

Fur bearers and trapping played an important role in the exploration and development of Nebraska. The harvest of our fur-bearer resource is part of every Nebraskan's heritage. Wise use of the resource and consideration for other people's property and personal rights can insure that trapping will remain a part of the heritage of future generations. The purpose of this publication is to help insure this heritage ... through the educational process. Knowledge of and respect for the resource, as well as consideration for other people, are the keys to perpetuating trapping as an outdoor activity. While primarily designed to assist …


Mule Deer Habitat Guidelines, Richard M. Kerr Aug 1979

Mule Deer Habitat Guidelines, Richard M. Kerr

United States Bureau of Land Management: Staff Publications

The purpose of this Mule Deer (Odocoileus hemionus) Habitat Management Guide is principally to assist BLM managers and biologists in planning for and managing mule deer habitat on public lands administered by the Bureau of Land Management. For many years Federal land management agencies have made the distinction between the Federal responsibility for managing habitat and the State prerogatives of managing native wild ungulate populations. Certainly the two are inseparably linked. These responsibilities, and up to now "symbiotic relationships", are probably best described succinctly in Title 43 of the Code of Federal Regulations Part 24.

An Objective Forecast Method Developed For Lake Ontario Induced Snowfall Systems, K. F. Dewey Feb 1979

An Objective Forecast Method Developed For Lake Ontario Induced Snowfall Systems, K. F. Dewey

School of Natural Resources: Faculty Publications

A research effort was initiated in 1976 to develop an objective lake-effect snowfall forecast model for each of the Great Lakes. It is the purpose of this paper to present the development and evaluation of the forecast method which was created for the Lake Ontario induced snowfall systems. All Lake Ontario lake-effect days were identified for a 10-yead period prior to the 1976 snowfall season. Upper air surface observations were combined with overlake data for these lake-effect periods. The dominant predictors were derived through the diagnostic ability of stepwise multiple discriminant analysis. The final product of this research effort was …


Lake Erie Induced Mesosystems- An Operational Forecast Model, Kenneth F. Dewey Jan 1979

Lake Erie Induced Mesosystems- An Operational Forecast Model, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

All Lake Erie lake-effect days for a 10-year period prior to the 1976-77 snowfall season were utilized in the development of an operational lake-effect snowfall forecast model. Upper air and surface observation were combined with overlake data and analyzed, using stepwise multiple-discriminant analysis. A nine-predictor mesoscale forecast model resulted from this statistical test and its performance was evaluated during the 1976-77 and 1977-78 snowfall seasons. The results of this evaluation indicate that it is possible to predict six intensities of the Lake Erie lake-effect snowstorm using this mesoscale model.
