To ensure that Western Shield’s management is effective, we monitor how native animal populations are responding to the reduction in predator pressure. The Parks and Wildlife Service monitors animal populations at selected sites within baited areas in various ways, usually by trapping (and releasing) the animals that need to be monitored.

Western Shield's monitoring shows that the baiting of foxes and feral cats is having a positive effect on the State's native animals. The success of Western Shield and previous programs has resulted in the removal of the pdfwoylie, pdftammar wallaby and pdfquenda from Western Australia's threatened species list

Unfortunately, monitoring since 2001 showed an unexpected and rapid decline in the population of woylies across the south-west of Western Australia.

The woylie is now re-listed as threatened, and the department is pdfconducting research to see why numbers are falling and to aid in the recovery of the species. to try to understand why the woylie populations declined so rapidly and to aid in the recovery of the species. Fortunately, woylie numbers have now started to increase but we will continue to monitor their populations closely.

Monitoring and evaluation also means that Western Shield can be regularly reviewed to make it even more effective by:

    • changing the program to test new potentially more effective management options
    • reallocating funds as new priorities emerge
    • improving baiting and monitoring.

     

      Wildlife stronghold

      Located in Western Australia's Wheatbelt, Dryandra is a stronghold for some of the State's most precious native animals - the woylie (Bettongia penicillata) and numbat (Myrmecobius fasciatus) - and the Parks and Wildlife Service is working with the community to secure their future.
