The trajectory and timetable of species to extinction is at least partly predictable. To provide forewarnings, a TSR Hub project, is identifying the Australian animal species at greatest risk and estimating the likelihood that they will become extinct over the next 20-year period, if there is no change in current management. Our rationale is that if governments, managers and the community are aware of which species are most imperilled, they can take emergency care to seek to prevent such extinctions – to act before it is too late.
