Abstract
An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.
The conditions for waterfowl which prevailed during 1980 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.
1980 was the fifth consecutive year of below-average rainfall in all five Meteorological Districts of the south-west. 1976 to 1980 was thus' the south-west's driest five-year period since 1913 at least.
Low rainfall during 1980 resulted in a further decline in the condition of wetlands throughout most of the inland south-west, Few gauged wetlands increased in depth by more than 50 cm over winter, and most were dry by November. Few of those which did contain water in November were more than 30 cm deep. Many important waterfowl sites were dry or virtually dry throughout the year.
As a result of the very poor conditions for
waterfowl during 1980, no duck-shooting season was declared for the summer of 1980-81.
