Federal Aid In Wildlife Restoration, Ronald A. Ryder

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

This report represents a compilation, analysis and summarization of data collected on the South Platte Management Area and deals primarily with game bird data collected by personnel of Project W-37-R. History, general description, and methods of operation are discussed, and recommendations for future operations given.

Briefly, the South Platte Management Area is located in Logan and Sedgwick counties, comprising over 11, 400 acres of state-owned land in four separate segments. The largest segment (more than 12,000 acres of deeded and leased land) lies along the South Platte River from Proctor to Red Lion. This, and a second area of 240 …

Spring Prairie Grouse Census - 1955, Reuel Janson

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

The 1955 spring prairie grouse census was conducted during the period March 30 to May 4. Census data were obtained by means of a survey of dancing and booming grounds on 18 automobile transects.

An average population density of 4.77 sharptailed grouse, and 0.71 prairie chickens per square mile was found. Comparable data for 1954 and 1955 indicate a 10 percent decline in the combined prairie and grouse population. The prairie chicken population declined considerably more than the sharptail population.

The extreme northern portion of the grouse range, Corson and Perkins Counties, experienced population gains of approximately 50 percent which …

Succession In A Dune Community At Mentor Headlands, Ohio, Harold G. Marshall

Biological Sciences Faculty Publications

Continual sand deposition on the Lake Erie shore, adjacent to the mouth of the Grand River, has led to the formation of a developing sand dune community and through the years a successional pattern of plant growth. An analysis was made of the general plant composition of the area by means of four transects directed from the bare beach inland. Definite zonation of specific plant species was present throughout the community in parallel formation. Named for the dominant plant types they contained, the major stages were: dune grass, poplar, aspen, and oak.

The Effect Of Grass Reseeding In Sagebrush Lands On Sage Grouse Populations, Richard W. Trueblood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The particular purpose of this study was to determine the effects of large-scale sagebrush reseeding projects on sage grouse populations and whether such effects were partly or entirely beneficial, neutral, or detrimental to the survival of such populations.

During two seasons of field work, the studies initiated on a short-time basis had the following specific objectives:

1. To compare the utilization by sage grouse of reseeded and non-reseeded lands for the seasonal activities of mating, nesting, raising a brood, fall coveying, and wintering.
2. To compare the utilization by sage grouse of reseeded and non-reseeded lands for daily activities of feeding, watering, …

The aerial survey proved to be very satisfactory when snow conditions are right. At I available cover must be well filled with snow, with very few bare spots in fields or other parts of the area. The birds tend to congregate on such bare places where it is very difficult to see them from the plane.

In 1951 a total of 40 townships were laid out as census plots in different parts of the state. In 1952 six new …

Evaluation Of Sprinkler Irrigation Systems In Northern Utah, Jay M. Bagley, Wayne D. Criddle

Reports

Summary and Conclusions: Sprinkler irrigation will continue to expand in Utah as well as in other irrigated areas of the world. This method of irrigation is suitable to all farm crops grown in the state and to most soils. It is particularly adapted to steep foothill areas where the water supply can be obtained at higher elevation and pumping is not necessary to develop pressure for the sprinkler systems. Also, much of the irrigated land of the state, particularly along the Wasatch front, is owned and operated by "part-time" farmers. Having the water under complete control and the irrigation schedule …

Stream Pollution, Ruth Patrick

United States Environmental Protection Agency: Publications

This paper discusses the various ways in which aquatic organisms may be of use in solving problems associated with waste disposal. Since many state and federal laws set forth that nothing may be discharged that is deleterious to aquatic life, the most expedient way to determine the effect of an effluent is to study the aquatic organisms themselves.

In every river that has not been adversely affected by pollution there is a great variety of aquatic life. These organisms do not represent a great mass of living things, but rather they are organized into an intricately balance systems, often referred …

A Survey Of Farm-Game Habitat Restoration Programs In Fifteen States, William H. Marshall

Other Publications in Wildlife Management

For at least twenty years the thinking of wildlife managers has been directed toward the importance of habitat in producing surplus game populations for hunting. The decline or disappearance of game populations - often over considerable areas - following changes in habitat brought about by agricultural, urban, or industrial developments demonstrates clearly the effects of the elimination of desirable habitat. Suitable habitat is basic to the survival of wildlife. Many field observations and experiences, as well as specific data from research, validate this conclusion. Where a harvestable surplus of game cannot be maintained because of changes made by man in …

Aerial Survey Township Areas, Willford L. Miller

Other Publications in Wildlife Management

In the year 1946, two townships of 36 square miles each were selected for experimental work in aerial censusing. The primary objective was to devise a technique for obtaining complete counts of upland game birds on limited areas during the winter months.

The aerial survey proved to be very satisfactory when snow conditions are right. All available cover must be well filled with snow, with very few bare spots in fields or other parts of the area. The birds tend to congregate on such bare places where it is very difficult to see them from the plane.

In 1951 a …

The Birds Of Riding Mountain National Park, Manitoba, Canada, J. Dewey Soper

Other Publications in Wildlife Management

Riding Mountain National Park is located in southwestern Manitoba within easy reach of important centres of population. From park headquarters at Wasagaming, it is only 140 miles southeast to Winnipeg, 57 miles south to Brandon, 35 miles north to Dauphin, and 102 miles to the International Boundary. Most of the surrounding country is devoted to agriculture.

The total park area approximates 1,148 square miles. Except for restricted tourist areas, it remains in a primitive condition, with unspoiled forests, prairies, streams, and lakes.

Up to the time the area was set aside as a park in 1929, comparatively little was known …

Measuring Waterfowl Habitat- Population Changes From Aerial Photos, Harvey W. Miller

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

A survey was conducted in 1953 to determine the feasibility of using aerial photography to measure the trends in available waterfowl habitat in the Nebraska Sandhills. This pilot survey included 96 one-square-mile sections systematically distributed over the area to give a 0.49 percent sampling rate.

The basic waterfo\o1l habitat types apparent on the aerial photos of these sections were identified and measured with a planimeter and map measure. These ascertained totals were then projected to obtain the estimated total of each habitat type in the study area.

A statistical analysis of the survey revealed that it would be necessary to …

To Rural And Star Route Carriers, Levi L. Mohler

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

Summary of your 1953 Winter Records

As we have mentioned before, an important item from the winter counts is the ratio of cock pheasants to hen pheasants after the season has ended. Your winter records showed 88 cocks per 100 hens for the state as a whole. In extreme southeastern Nebraska (where pheasants are scarce), and for central and western Nebraska, you recorded more cocks than hens. For most of the eastern third of the state (where most of the pheasant hunting is done) you recorded two cocks for every three hens. This reflects the removal of more cocks by …
