This project will improve our understanding of feral cat impacts and how to mitigate those impacts. At national scale, it will collate and analyse large and diverse sets of data to estimate cat distribution and abundance, and measure predation rates by cats on birds, reptiles and mammals, and to identify the ecological traits that make some species more susceptible to cat predation than others. The project will also collate research findings from other related TSR Hub research, for example to help identify cat density thresholds that would allow vulnerable native species to co-exist with cats.
