A Threatened Plant Index for Victoria

This project has developed a Threatened Species Index (TSX) for Australia to assist policymakers, conservation managers and the public to better understand how population trends across Australia’s threatened species are changing over time. Here, for the first time, we present the Threatened Plant Index, which combines monitoring data on threatened species populations from across the country. The index includes data for taxa (meaning species and subspecies) that are Near Threatened, Vulnerable, Endangered or Critically Endangered under Australian legislation (EPBC Act) and/or internationally (on the IUCN Red List as of March 2020). These data come from monitoring programs where plant populations have been surveyed at the same place in multiple years with a standardised method; this makes it possible to detect changes over time.
