Since 2015, members of ICON Science have been working with the Office of the Threatened Species Commissioner to assess the national management of feral cats across Australia. This work is part of the wider Threatened Species Strategy, and recognises the significant threat to Australia’s native species that is posed by feral cats.
Taking place across 5 years, this work aimed to document who is engaging in feral cat control, how many cats have been removed and how close Australia is to meeting the ambitious targets set out in the Threatened Species Strategy.
We are pleased to share the final report from this 5-year project, which has involved a cross section of the interdisciplinary team here at ICON Science.
In addition to collated data from government reports and repositories, we undertook strategic online surveys of individuals and organisations who are most likely to be undertaking feral cat control. The 2020 online survey collected raw numbers of feral cats controlled, control area estimates, control methods and information on the type of environment where work has taken place. We also asked participants to indicate the location of their feral cat control activities (see featured map at top of post).
We used the variation in feral cat control numbers collected from the sample of local councils, farmers and shooters/hunters who took part in the survey to project the number of cats controlled on a national scale. This allowed us to provide a bounded estimate for the total number of feral cats removed between 2015 & 2020.
Our final 5-year cumulative estimate for the number of feral cats controlled ranges between 1,493,520 and 1,669,568 cats, with a most likely estimate of 1,581,544 cats having been removed from the environment since 2015.
– 2917 individuals completed the online survey, 61% of whom said they were engaged in feral cat management (the survey was targeted at groups likely to be undertaking cat control).
– In our survey sample, feral cat control activities were concentrated in the more populous areas of eastern Australia.
– Non-government organisations engaged in feral cat control activities report most activity taking place in urban areas.
– Individuals are more likely to be operating in farmland or scrubland.
