Summary: This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their `toad-smart¿ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.
