Noise generated by bird scaring devices used by growers attempting to protect their crops often creates conflict with residents at urban/rural interfaces. The Environment Protection Authority of South Australia has developed guidelines for the use of these devices with input from a working party of community, primary producer and local and state government representatives. The guidelines incorporate the concept of a performance-based objective (PBO) to delineate “unreasonable interference” and use the Accumulated Peak Level (APL) as the appropriate measure of impulsive noise generated by devices like gas guns. Separate APLs have been set for primary production zones and interface areas between primary production and residential, rural living or buffer zones. A different PBO is set for electronic bird scaring devices that generate high tone noise modulating in frequency and amplitude.
A central concept in the guidelines is that noise-generating devices are likely to be most effective when used strategically and as part of a multi-faceted approach to bird management. To assist growers, the guidelines include an outline of a bird management plan and provide access to information on developing such a plan. This paper summarises the processes in the development of the guidelines and the basis of the principles therein.
