Some Concepts In Rangeland Management, R B. Hacker

Journal of the Department of Agriculture, Western Australia, Series 4

The arid and semi-arid zones of Australia occupy about 75 per cent of the land mass. The pastoral industries are located within these zones and, although productivity per unit area is low, the region nevertheless constitutes one of the nation's valuable renewable resources.

If properly managed, such a resource may be maintained as a productive asset indefinitely.

Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones

Journal of the Department of Agriculture, Western Australia, Series 4

In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture.

Samphire For Waterlogged Salt Land, C V. Malcolm, G. J. Cooper

Journal of the Department of Agriculture, Western Australia, Series 4

For non-waterlogged and mildly waterlogged salt land a number of salt-tolerant shrubs may be used for forage production.

Areas which are highly saline and regularly waterlogged are not suited to these shrubs. However, during trials with shrub species, samphires (Arthrocnemum spp.) were found to volunteer and grow well on these sites.

Research into the use of samphires has shown that it is possible to harvest seed and obtain a seed sample suitable for sowing through a drill. Established samphire stands provide useful grazing in many parts of the Western Australian wheatbelt.

Forage Production From Shrubs On Saline Land, C V. Malcolm

Journal of the Department of Agriculture, Western Australia, Series 4

In the first volume of the Journal of the Department of Agriculture in the year 1900, the results of experiments at Tulare Experiment Station in California on the growing of Australian saltbushes are reported.

Seed was first sent from Australia by Baron von Mueller in June, 1881. Three species of saltbush (A. semibaccata, A. numularia and A. vesicaria) are all reported to have grown well.

Although C. A. Gardner in 1929 suggested the growing of saltbushes for forage, the earliest and clearest recommendations are those of Teakle and Burvill in 1945.

Early research tended to concentrate mainly on the possibility …

Phytoplankton Distribution And Water Quality Indices For Lake Mead (Colorado River), Robert D. Staker, Robert W. Hoshaw, Lorne G. Everett

Publications (WR)

Phytoplankton samples were collected in Lake Mend 6 times from September 1910 to June 1971 for 8 stations at depths of 0. 3, 5, 10, 20, and 30 m. These samples were processed through a Millipore filter apparatus and 79 planktonic algae were identified. Algal divisions represented were Bacillariophyta, 42 species; Chlorophyta, 18 ; Cyanophyta, 9; Chrysophyta, 3; Cryptophyta, 3; Pyrrophyta, 2; and Euglenophyta, 2. Blue-green algae were dominant in late summer and fall; green algae, diatoms, and, cryptomonads in winter; and green algae in spring. The early summer flora was best represented by the Chlorophyta, Cryptophyta, and Chrysophyta. Palmer's …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

The Mormon Role In Irrigation Beginnings And Diffusions In The Western States: An Historical Geography, Kelly C. Harper

Theses and Dissertations

Irrigation has played an important part in the development of the Western States. Its beginnings have often been associated with the Mormon settlement in Utah. However, irrigation had its inception in the West long before the Mormons came to the Great Basin in 1847. The spatial extent of irrigation before this date included limited acreage in nearly every Western State.

Before their arrival in the Great Basin the Mormons had become acquainted with irrigation methods. Knowledge of irrigation had diffused to them primarily from the Spanish in the Southwest. Thus, they were well prepared to begin their irrigation enterprises in …

The Mediterranean Coast Of Israel: A Planner's Approach, Sophia Professorsky

Marine Affairs Theses and Major Papers

The coastal zone of Israel is facing an ever-growing pressure of varied and conflicting land uses. Spreading urbanization, from Nahariya in the north to Ashkelon in the south, gnaws agricultural areas; the needs for commercial ports and industrial plants stand in conflict with recreational uses of the seashore and, as described before, the natural conditions of land shelf structure, topography and climate, are favourable for both industry and residence so that the narrow stretch of the coastal zone attracts more and more of them.

Mathematical Simulation Of Temperatures In Deep Impoundments: Verification Tests Of The Water Resources Engineers, Inc. Model - Horsetooth And Flaming Gorge Reservoirs, Engineering And Research Center, Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

Successful use of predictive mathematical models requires verification of the accuracy of the models by applying them to existing situations where the prediction can be compared with reality. A Corps of Engineers' modification of a deep reservoir thermal stratification model developed by Water Resources Engineers, Inc., was applied to two existing Bureau of Reclamation reservoirs for verification. Diffusion coefficients used for the Corps' Detroit Reservoir were found to apply to Horsetooth Reservoir in Colorado, for which very good computer input data were available. The Detroit diffusion coefficients gave a reasonable simulation of Flaming Gorge Reservoir in Wyoming and Utah, which …

Social Costs And Benefits Of Water Resources Construction, Rabel J. Burdge, K. Sue Johnson

KWRRI Research Reports

This report analyzes and describes the process of relocating individuals and families who must move due to reservoir construction in Kentucky utilizing data collected in previous research. These data come from four separate studies: a study of community attitudes toward reservoir construction (Johnson county where the Paintsville reservoir is to be constructed), interviews with people who are slated for relocation when the Taylorsville reservoir is constructed, and two sets of interviews with people who have already been relocated due to reservoir construction (Cave Run and Carr Fork).

Psychological, social, economic and material costs and benefits associated with forced relocation are …

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Aerially Applied Methiocarb Spray For Protecting Wild Lowbush Blueberries From Birds, Rene M. Bollengier, Joseph L. Guarino, Charles P. Stone

Bird Control Seminars Proceedings

Ripening blueberries are subject to serious damage by a variety of bird species. Through a questionnaire survey, Pearson (1958) calculated that losses of highbush blueberries to birds in Massachusetts averaged about $38,000 a year in 1955-57. From a 1972 questionnaire on bird damage to highbush blueberries directed to individuals in 14 states, Mott and Stone (1973) estimated that birds damaged at least 5% of the crop, representing a minimum nationwide loss of about $1.6 million. Most species of birds that feed on blueberries are not only desirable but also protected under the Migratory Bird Treaties Act. Any means of reducing …

Fao Quelea Research In Africa, Jeffrey J. Jackson

Bird Control Seminars Proceedings

Large scale grain growing schemes are developing rapidly in Africa and the importance of birds as pests becomes more evident each year. Although the potential production of cereals is quite high in some parts of Africa, effective methods for protecting the new schemes from bird damage will have to be developed if their food raising potential is to be realized. The best known of the avian pests of cereals in Africa is Quelea quelea. In addition to their importance as pests their notoriety is due to their intensely gregarious nature. The cloudlike feeding swarms and dense nesting colonies with millions …

Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell

Bird Control Seminars Proceedings

On December 5, 1965 the Governor of Wisconsin signed into law a statute permitting claims against the State for damages to crops by wild geese and ducks. This law had been rushed through the legislature in the wake of a rash of crop depredation complaints caused by Canada Geese in their off-refuge feeding flights from the Horicon National Wildlife Refuge. This paper reviews our experiences with waterfowl depredations in the development of a cooperative program by State and Federal wildlife agencies that has held a potentially serious wildlife problem to a minimum of financial losses and public relations concern.

Use Of Perches At Refinery Sites, J. J. Dill

Bird Control Seminars Proceedings

I was listed to speak about bird control on industrial sites, so I have selected three or four of the more interesting jobs that we have worked on over the past ten years. Naturally the ones that the pest control firms call us about are those that they have tackled from several different angles and been unable to solve. As a result of this, we have had several really interesting bird control jobs in conjunction with pest control firms. I think each one of them will point out different problems and ways to solve them. The first of the jobs …

Application Of An Avian Bioenergetics Simulation Model To Red-Winged Blackbird - Crop Relations, John A. Wiens, Melvin I. Dyer

Bird Control Seminars Proceedings

The impact of bird populations upon the properties or processes of ecosystems is mediated through patterns and magnitudes of energy flow. This impact may be either direct, by processing of large quantities of energy or nutrients, or indirect, through feedback control of other ecosystem rate processes or components. In either case, however, the impact is a result of the population dynamics and the pattern and magnitude of food consumption of the birds. Recent research by several groups points to a relatively small direct impact on birds on most natural ecosystems (Wiens 1973). Impact through feedback control, a more difficult relationship …

Tests Of A Potential Method For Decoying Starlings To Bait Stations, Robert E. Williams, Robert G. Schwab

Bird Control Seminars Proceedings

The costs of existing Starling control programs prompted the design and test of an alternative method for removing significant numbers of Starlings from heavily damaged areas. The procedure involved the placement of taxidermically prepared adult Starling skins on and near bait stations, accompanied in some cases by broadcasts of recorded Starling vocalizations. Previous studies had indicated that bait stations unaccompanied by live Starling decoys were not acceptable to the birds. Although non-toxic baits were used during these tests to determine the attractability of the stations, ultimate substitution of chemically treated toxic baits was envisioned.

Investigation Of Bird Migration And Mortality At The Omega Navigation Station, Lamoure, North Dakota: Fall 1972 And Spring 1973, Michael L. Avery, Paul F. Springer

Bird Control Seminars Proceedings

An investigation of bird migration and mortality at the U.S. Coast Gaurd’s Omega Navigation Station, located in the flood plain of the James River near LaMoure, North Dakota, began in September 1971 following the completion there of the 1,200-foot transmitting tower. The objectives of the study are: 1. To determine the nature of bird migration through the tower area and adjacent regions. 2. To determine the magnitude of bird losses caused by the tower. 3. To determine the influence of weather patterns on bird migration and losses. 4. To develop and evaluate methods for reducing bird losses at towers. This …

Impact Of Cooling Towers On Bird Migration, Edward J. Rybak, William B. Jackson, Stephen H. Vessey

Bird Control Seminars Proceedings

Construction of the Davis-Besse Nuclear Power Station on the SE shore of Lake Erie near Port Clinton, Ohio brings a massive, natural draft cooling tower (495 ft. high and 410 ft. wide at base) into migration pathways. Preoperational observations were undertaken to determine whether conditions existed under which the station structures intercepted migrating birds. Preliminary observations were made at the site (Fig. 1) in the fall of 1972 and intensified during the spring and fall migrations of 1973. Construction on the shell of the cooling tower was not completed until late in 1972; thus the full height had not been …

A Program For Developing Male Chemosterilants For Red-Winged Blackbirds, Joseph L. Guarino, Edward W. Schafer Jr.

Bird Control Seminars Proceedings

Red-winged Blackbirds (Agelaius phoeniceus) are one of the primary species of birds contributing to agricultural damage throughout the United States. Methods have been developed for reducing the damage they cause to ripening corn (De Grazio et al. 1971; 1972), sprouting corn (Stickley and Guarino, 1972), ripening rice (DeHaven et al. 1971), and windrowed peanuts (Mott et al. 1972). These methods frighten or repel Redwings from crops; however, in some situations, techniques are also needed to manage specific problem-bird populations by reducing their numbers. At present, the primary methods for reducing large numbers of problem birds involve the use of chemical …
