Btec Campaign Ends In 1992, Carole A. O'Dwyer

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

BTEC, the national brucellosis and tuberculosis eradication campaign, is funded jointly by cattle producers and the Commonwealth and State Governments. When the campaign was launched on July 1,1970, its aims were to remove a potential export trade barrier and to improve the level of herd health. The campaign should be substantially completed by the end of 1992.

The Kimberley region of Western Australia was declared free of brucellosis in April 1980, and the entire State was declared free in 1985, the first mainland State to achieve this status.

All parts of Western Australia south of the 20th parallel were declared …

Grazing The Rangeland : Towards An Understanding, Alec Mcr Holm, Donald Burnside

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

Western Australia's rangelands are those parts of the State, excluding deserts, where inadequate rainfall prohibits their development for a cultivated agriculture. About 980,000 sq. km of these rangelands are held as pastoral leasehold land, with a total of 450 individual station businesses. These native pasture lands support about 2.5 million sheep and 850,000 cattle. The rangelands can be divided into three main natural regions, each of which has a distinct climate and vegetation. These are the Kimberley region; the north-western spinifex region, which includes the Pilbara; and the Acacia shrubland region of the Gascoyne, Murchison, Goldfields and Nullarbor areas. This …

1080 Does Not Threaten The Northern Quoll, D R. King

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

The poison 1080 is used in baits to control animal pests such as dingoes, rabbits and, indirectly, foxes. There is always the risk that some "non target" animals, particularly our native animals, might eat the baits and die, although investigations indicate that many southern native mammals are tolerant of 1080. The compound 1080 is found in many native plants growing in southern Western Australia, in the genera Gastrolobium and Oxylobium, and over the centuries native animals have built up resistance to its effects. Until recently the tolerances to 1080 of only a few animals from the pastoral areas were known. …
