Water Economy For Lawns And Gardens, K S. Cole
Water Economy For Lawns And Gardens, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
Much of the summer water consumption occurs because it is widely believed that heavy summer watering is necessary. Householders often mistakenly water heavily to keep their gardens green and growing. Many may not realise that gardens can be kept vigorous and healthy with much less water than is commonly applied.
Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones
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.
Grain Moisture And The Weather : What Can The Records Tell Us?, M W. Perry, P. A. Fievez
Grain Moisture And The Weather : What Can The Records Tell Us?, M W. Perry, P. A. Fievez
Journal of the Department of Agriculture, Western Australia, Series 4
The expansion of cereal production in areas along the south coast has exposed harvesting problems associated with high grain moisture.
A grain delivery standard of 12 per cent moisture means that, in the absence of grain drying facilities, harvesting times in the field are restricted to those hours when grain moisture falls below this figure.
Grain moisture, however, remains the major problem and for planning purposes, producers require an estimate of the harvesting time available in a given year. This will depend on all the climatic variables which affect grain moisture. These include rainfall and dew which deposit water directly …

Conservation Of The National Estate, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
In 1973 the Australian Government established a Committee of Inquiry under Mr. Justice R. M. Hope to inquire into the National Estate. Under its terms of reference the Committee was to assess the nature and condition of the National Estate and the measures which were being and should be taken for its preservation and enhancement.
Officers of the Department of Agriculture recognise that there are basic natural resources such as land, water, gene material and ecosystems which are essential elements of the National Estate held in trust by successive generations.
In a submission to the Inquiry, matters of particular concern …

Measuring The Intangible Values Of Natural Streams, Part Ii, John A. Dearinger, George M. Woolwine, Charles R. Scroggin, Daniel R. Dolan, James S. Calvin
KWRRI Research Reports
This report describes the work done during Part II of a project which had as its aim the development of a way to quantify those intangible values peculiar to a small stream and its watershed. Part I was concerned with an application of the "uniqueness concept" in the evaluation of fifty-eight Kentucky streams. The results of this effort are in Report #40, U. K. Water Resources Institute (1971).
During the second part of the project:
- A method was developed whereby peoples' preferences for natural landscapes could be measured. The method utilized projected color slides and a rating system based on …
The Mediterranean Coast Of Israel: A Planner's Approach, Sophia Professorsky
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.

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 …

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 …

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 …
Crop Depredations By Waterfowl In Wisconsin, Richard A. Hunt, James G. Bell
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.
New Materials And Methods, Jerome F. Besser
New Materials And Methods, Jerome F. Besser
Bird Control Seminars Proceedings
I have several short thoughts I would like to share with you. This conference has presented few new methods, but most of you do not need a new method to solve many of the problems you encounter. Some of the old methods, if used with much enthusiasm, will work just as well. One reason that few new methods are being developed is the time taken for the development of old methods. I would like to leave you with one thought, and I think this is particularly urgent in the chemical area. We have been trying to develop chemical agents for …

Npca Education Committee, James Steckel
Bird Control Seminars Proceedings
The major thrust of the Education Committee results from the rather urgent need to implement interesting programs in which supervisors may train for examination and certification under the qualifications of the pesticide act. While it is not easy at this time to determine what certification is going to be, what supervisors are going to be involved, what kind of examination they are going to have to take, and how the state is going to interpret all of this, we therefore cannot be specific. The wheels are grinding away, and as you know, the timetable is winding down; and we may …

Tests Of A Potential Method For Decoying Starlings To Bait Stations, Robert E. Williams, Robert G. Schwab
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.
Radiotelemetry For Studying Problem Birds, Olin E. Bray
Radiotelemetry For Studying Problem Birds, Olin E. Bray
Bird Control Seminars Proceedings
Bird problems are much easier to solve if information is available on the behavior of the birds involved. Banding, color-marking, and visual observations have provided only general information on the behavior of problem birds. In order to continuously monitor the activities of birds causing problems, personnel in our Bioelectronics Unit and I developed a radiotelemetry system. A. Lawrence Kolz, George W. Corner, Erwin W. Pearson, and Richard E. Johnson of the Bioelectronics Unit provided the knowledge of electronics and many days of tedious work necessary to develop this system.
Fao Quelea Research In Africa, Jeffrey J. Jackson
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 …
Local Fall Movements Of The Red-Winged Blackbird In Central New York, Noel J. Cutright
Local Fall Movements Of The Red-Winged Blackbird In Central New York, Noel J. Cutright
Bird Control Seminars Proceedings
Studies into the post-breeding season activities of the Red-winged Blackbird (Agelaius phoeniceus) recently have received greater attention. The United States Fish and Wildlife Service began a massive study involving the finding of winter concentrations of blackbirds and the marking of individuals. Meanley (1965, 1971), the most conspicuous name in the literature involved in this work, has recently published observations on the roosting behavior of the Redwing in southern United States. This wave of interest in blackbirds also is present in New York. Growers in the Finger Lakes Region have become quite concerned with the extent of damage to their corn. …

Now that Avitrol has been registered for use on field corn, the next step is to get the chemical registered for use on other crops. Two of the most important are sweet corn and sunflowers. Accordingly, personnel at the Bureas of Sport Fisheries and Wildlife, Sandusky, Ohio field station planted 16 experimental plots each in Sandusky and Ottawa Counties in Ohio this past summer to gather data on the efficacy of Avitrol when used on sweet corn and sunflowers. Of the 16 plots in each county, eight were sunflower plots, eight were corn plots. We applied Avitrol to four of …

A Bibliography On The Red-Winged Blackbird, Noel J. Cutright
A Bibliography On The Red-Winged Blackbird, Noel J. Cutright
Bird Control Seminars Proceedings
Following the completion of my doctoral dissertation on the Red-winged Blackbird, I decided to compile a bibliography on the species. This bibliography updates and expands the selected bibliography on Redwings prepared by Mealey and Mitchell in 1966. No effort was made to list the many progress and final reports on various aspects of blackbird research issued by the Bureau of Sport Fisheries and Wildlife. Literature citations follow the Style used in The Journal of Wildlife Management.
Legal Requirements And Status Of Protected Bird Species, Richard N. Smith
Legal Requirements And Status Of Protected Bird Species, Richard N. Smith
Bird Control Seminars Proceedings
Migratory birds found in North America are protected by the Migratory Bird Treaty Act, which implements migratory bird conventions between the United States and Great Britain and the United States and Mexico. An amendment to the Act in 1972 placed all migratory bird species except for exotic species such as Starlings, Pigeons, and House Sparrows in a protected status. There are sections within the Act that allow for the issuance of permits to take protected species. Those sections that are of the most concern to the pest control operator deal with certain blackbird species that cause agri- cultural crop damage …
Insurance, Mark Weisburger
Insurance, Mark Weisburger
Bird Control Seminars Proceedings
We have been working with exterminators on the insurance problems for thirty-five or so years. Recently PCO’s have been doing much in the way of bird control. There does not seem to be anyone that we know of who does strictly bird control insurance, so our group always ties it in with our pest control. I feel that nothing touches everyone so regularly, with the exception of the federal government, as your insurance premiums. I would like to discuss with you the causes and results of accidents and how they can effect insurance premiums.
Bird Control In Milwaukee : A Case History, Laverne A. Penn
Bird Control In Milwaukee : A Case History, Laverne A. Penn
Bird Control Seminars Proceedings
In planning a city-wide pigeon control program, many problems must be considered to conduct such a program safely and efficiently. The City of Milwaukee Health Department has been engaged in some degree of nuisance bird control activity for more than thirty years. Early attempts at bird control consisted of using fireworks, rubber snakes, paper mache owls, and other devices to prevent starling roosting. All met with very limited success and were eventually abandoned. Until the post World War II period, Milwaukee, like most large cities, was plagued by an abundance of homeless pigeons. Pigeons were abundant on downtown streets, commercial …
