Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman
Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman
Theses, Dissertations and Capstones
Differences in the physical size of male white-tailed deer from varying parts of West Virginia were known to exist a considerable number of years before any sophisticated attempts were made to explain them. Prior to 1940, the state's deer herd had been making a slow, but increasingly steady, comeback from a period of extreme scarcity around the turn of the century. To supplement the original remaining stock, shown in Figure 1, page 2, a deer restocking program was initiated in 1923. In 1937, federal legislation, in the form of the Federal Aid to Wildlife Restoration Act, gave added support to …

Control Of Weeds In Garden Areas, Geoffrey A. Pearce
Control Of Weeds In Garden Areas, Geoffrey A. Pearce
Journal of the Department of Agriculture, Western Australia, Series 4
THE present-day gardener does not appear to relish the tedious job of removing weeds by hand. It is a never-ending task and no sooner is one germination controlled than another appears.
Modern herbicides provide a ready answer for overcoming the weed problem in the home garden, but it is essential to select the correct chemical and to understand its limitations.

Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH the flora of Western Australia strongly attracted early botanists and collectors, it was virtually neglected by settlers faced with a century or more of hard pioneering.
Only recently has enthusiasm for our remarkable flora developed within the State and, with the formation of sponsoring societies and the establishment of the Kings Park Botanic Gardens, native species have become popular in home and civic gardens.

Ornamental Trees For The Farm Garden, P Luff
Journal of the Department of Agriculture, Western Australia, Series 4
THE need for trees in the farm garden is being realized by many people.
Trees around the homestead are required to give such features as shade, colour, fragrance and many other advantages to generally make an area more livable.
Besides these advantages, trees appear to help smaller plants flourish by increasing the humidity and providing various degrees of shade and sunlight.

Journal of the Department of Agriculture, Western Australia, Series 4
UNDER natural conditions animals have considerable control over their movements and over their proximity to each other.
Today, however, there is a trend in animal husbandry towards greater intensificaton, and this is most evident in the poultry industry.

An Estimate Of Winter Utilization Of The Cedar Creek Natural History Area By The White-Tailed Deer, L. D. Frenzel Jr.
An Estimate Of Winter Utilization Of The Cedar Creek Natural History Area By The White-Tailed Deer, L. D. Frenzel Jr.
Journal of the Minnesota Academy of Science
Estimates of utilization of the Cedar Creek Natural History Area by the white-toiled deer (Odocoileus virginianus borealis) during the winters of 1963 and 1964 were mode using the deer-drive method. The 1964 estimate is considered the more realistic index of winter utilization by deer of the area because of increased efficiency of the drive, weather conditions favoring deer-drive technics, and agreement with results of pellet-count studies mode independently on the area.

THE science of animal husbandry deals with all those things which affect the welfare and productivity of our domestic animals.
The relative emphasis placed on welfare and productivity depends on whether the animals are kept as pets or for profit.

Spraying For Grasshopper Control, T J. Tozer
Spraying For Grasshopper Control, T J. Tozer
Journal of the Department of Agriculture, Western Australia, Series 4
A BIG increase in cereal growing in the "hopper" belt has brought a general improvement in the grasshopper situation over the past few years.
This highlights the emphasis entomologists have placed on cultivation as the best known way of controlling grasshoppers.
