Abstract
Auditory deterrents such as the Roo-Guard® sound emitters (Shu-Roo Australia Pty Ltd) have been used to keep kangaroos off crops and airstrips. We tested the efficacy of the Roo-Guard® Mk II sound emitter in deterring tammar wallabies (Macropus eugenii) from a known source of food on Garden Island, Western Australia, where up to 400 tammars are killed yearly by vehicles. The device was not effective in deterring the tammars from the food even when an alternative source of food was available. It was concluded that the Roo-Guards in their present form are not suitable to keep tammars off the roads of Garden Island.
