ROTAP

Rare or Threatened Australian Plants, usually abbreviated to ROTAP, is a list of rare or threatened Australian plant taxa. Developed and maintained by the CSIRO, the most recent edition lists 5031 taxa. The list uses a binary coding system based on the IUCN Red List categories for "Presumed Extinct", "Endangered", "Vulnerable", "Rare" or "Poorly Known". However, it also provides for additional information such as geographic range and occurrence in protected areas.
